5 RECOMMENDED SYSTEM REQUIREMENTS 5/140 1 RECOMMENDED SYSTEM REQUIREMENTS Supported Operating Systems Windows Vista, Windows 7 and 8 (32 and 64-bit) are supported. Comment for MAC OS systems: ReluxPro cannot be run natively on MAC OS or other Linux derivatives. On these platforms it runs only inside an emulation layer called Virtual Machine. To be more precise, a MS Windows Virtual Machine must be created using visualization software such as Virtualbox. Further links: en.wikipedia.org/wiki/virtualbox en.wikipedia.org/wiki/virtual_machine Supported Graphics Cards Graphics cards should fulfil the requirements in chapters 2.1 and 2.2. video memory (VRAM): minimum 256 MB. optimal: 512 MB or more. at least OpenGL version 3.0 is needed. Note: ReluxPro tries to detect potential graphics card incompatibilities by switching to Mesa mode. Mesa mode processes 2D and 3D visualisation as a software emulation, which means the hardware acceleration of the graphics card cannot be used. The advantage of this mode is its reliability. The downside is slower execution of ReluxPro. This mode can be activated manually in ReluxPro via Extras->Options->General settings Main memory (RAM) Minimum required: 2 GB RAM Optimum: 4 GB RAM or more Relux Informatik AG, Fit for ReluxSuite 2015,

6 RECOMMENDED SYSTEM REQUIREMENTS 6/140 ReluxPro is a 32-bit program. This means the program can use 2GByte RAM at most. One exception is the standard calculation engine for artificial and daylight calculations. This can use the entire main memory of 64-bit operating systems, and thus makes it possible to calculate very large projects. The Raytracer module is still a 32-bit program and therefore has to observe the 2GB RAM threshold Processor (CPU) Minimum required: Dual core Intel or AMD processor with at least 2GHz clock frequency. Optimum: Intel or AMD processors with 4 or more cores. For example, the AMD Phenom series or Intel Core i7 series. Currently only standard Radiosity lighting calculations are multi-core and Hyperthreading capable. 1.2 Installation of the program and the luminaire catalogue off a DVD Please close all other programs before installing the program. Place the DVD in your DVD drive. The setup for ReluxSuite ought to start automatically. If the setup routine does not start, this probably means that the "Autostart" function has been deactivated. You should open Windows Explorer, select the drive in which the Relux DVD is located and start the setup manually by double-clicking on the start.exe file. The installation program starts with the opening screen for selecting the language. The language selected here applies for the installation only. Different languages can be selected later on when using the program and also for the program outputs. You start the installation of the main program by pressing on ReluxSuite (Fig. 1). Fig. 1 Relux Informatik AG, Fit for ReluxSuite 2015,

7 RECOMMENDED SYSTEM REQUIREMENTS 7/140 Note: If an older Version (up to Relux Professional 2007) is still installed on your system, enter a new path for the ReluxSuite Version. If you need your projects from Relux Professional 2007 and the imported LDCs at a later date, you can copy these into the ReluxSuite directory. You should now select Install ReluxSuite. You should read the licence agreement and accept it so that you can continue with the installation (Fig. 1). Select the country in which you are located. In the next window, you can specify a path for the installation of ReluxPro. The default proposed for Relux is C:\Program Files. Fig. 2 Once the setup routine has copied the program data, you can specify the language for the user interface, the outputs and the database. You can change these settings in the program at any time (Extras Language). You can choose whether you install the manufacturer data locally (this is recommended if you have sufficient memory space, duration approx. 20 minutes) or whether you wish to use this data off the DVD. In the case of a network, we recommend copying the data to a network drive, so that all users can access it. You can select the manufacturers by double-clicking the tick or by using +++ or ---. If necessary please refer to the Relux Professional 2007 manual for a more detailed description of the installation process. Relux Informatik AG, Fit for ReluxSuite 2015,

8 RECOMMENDED SYSTEM REQUIREMENTS 8/ Installation of the program as a download Fig. 3 If you do not have a ReluxPro DVD, you can download the program free-of-charge from the Relux Informatik AG homepage at (Fehler! Verweisquelle konnte nicht gefunden werden.). 1.4 Relux Online Update Once the installation has been successfully completed, you can start ReluxPro for the first time. We recommend that you now update ReluxPro and the manufacturer databases that have been installed via the menu option Help - Online Update. Your PC needs to be connected to the Internet to do this. The update manager will start, and you can specify whether ReluxPro should look for updates on a regular basis. We recommend you to leave this option switched on, with a time interval of two weeks. You will then always be able to work with the latest program and database versions (Fig. 4). Relux Informatik AG, Fit for ReluxSuite 2015,

13 PART 1: GETTING STARTED IN 5 MINUTES 13/140 3 PART 1: GETTING STARTED IN 5 MINUTES The following features will help all advanced Relux users to switch to the new ReluxSuite. Beside this quick familiarisation with ReluxSuite , interested Relux users will find all the information on Relux Suite in the second part of this manual. Please refer to Part 2 for a more detailed description of these features. 3.1 ReluxNet Search-Find-Utilize Now you can select lights, lamps and sensors and gather details of their characteristics. You can share this knowledge with your colleagues and continue to use it for planning lighting systems in various programs. For this, you can use any type of media such as your PC, tablet or smartphone with internet access. 100 international manufacturers provide you with approximately 1 million lights, 2,000 lamps and 1,000 sensors in uniformly illustrated form. This is made possible by selecting the criteria appropriate for you. For example, you select the interior, an assembling arrangement, ceiling, etc. and you will notice how the range of offers gets reduced in steps until you have found your optimal project lamp. We are convinced that in future you can save a lot of time by using ReluxNet. Fig. 8 On the right at the top edge of the page you can register for free (Fig. 8), for example, to create your own lists of favourites. Also you can import any lighting files (Eulumdat, IES) and create your own data sheets for these products. Step 1: Enter address Step 2: Set a password Relux Informatik AG, Fit for ReluxSuite 2015,

14 PART 1: GETTING STARTED IN 5 MINUTES 14/140 Step 3: Receive your confirmation mail and confirm registration with ReluxNet. Done. Note: Optionally, you can also invite your colleagues to share the products you have created and manage. This saves time and creates synergies. 3.2 gbxml-import with ReluxPro The Green Building XML format (gbxml) has been designed as an open data format. GbXML allows you to easily transfer building data (building hierarchy, geometry, daylight openings, doors, etc.) from Building Information Models (BIM) to engineering or analysis software. Currently, GbXML is being integrated into a variety of CAD programs and Engineering Tools and supported by leading 3D BIM vendors. The new ReluxPro provides, like the CAD Import - two different possibilities of importing gbxml files. The first option involves selecting the option Project Import (Fig. 9) in the Start menu of ReluxPro and creating several new scenes using an imported gbxml file. In this, any existing doors or windows are placed at the same time. The second option is to import more gbxml data into an existing project. Follow the Menu File Import Scene. Fig. 9 Supplemented Start dialog window Clicking on the option Import Project opens up as usual the input window for the project data. (Fig. 10) Relux Informatik AG, Fit for ReluxSuite 2015,

15 PART 1: GETTING STARTED IN 5 MINUTES 15/140 Fig. 10 Dialog window Enter Project data As early as the next step, a gbxml file can be imported in the menu Import Room. (Fig. 11) Fig. 11 Dialog window Import Room Other preparations or creating the building hierarchy (Building Floor Scene) is not necessary because all scenes are already assigned logically to their floors when importing. (Fig. 12) Relux Informatik AG, Fit for ReluxSuite 2015,

16 PART 1: GETTING STARTED IN 5 MINUTES 16/140 Fig. 12 Dialog window Import gbxml Furthermore, in the plan view all the scenes are placed in their correct positions, allowing the user a rapid overview of all floors along with the scenes. In this regard, the current version of ReluxPro differs considerably from previous versions. (Fig. 13) Fig. 13 Floor overview of the new ReluxPro Version 2015 So as to start planning lights and lighting systems for individual scenes, it is necessary to move from the floor overview into a single scene. By double-clicking a room enclosing wall switch into the desired scene and enable the editing mode. As usual, working with ReluxPro is convenient despite a possibly large number of scenes. The Relux Informatik AG, Fit for ReluxSuite 2015,

17 PART 1: GETTING STARTED IN 5 MINUTES 17/140 newly-named menu group Project (see Fig. 14) allows you to switch back into the floor overview if necessary (the leftmost icon in the menu group Project ). Fig. 14 Menu group Project In the menu group Project, as usual, a so-called combo is located in the middle (Fig. 15). On clicking, the list of all available levels is displayed and, slightly indented, also the list of all available scenes. Here, you can select individual rooms, or switch between the floors of a building. Fig. 15 Combo box in the menu group Project The following two figures show the view of a ground plan in the floor overview, and then in the editing mode of a scene. 3.3 CAD-Import with ReluxPro (planning of entire floors) The new ReluxPro now also includes the possibility of viewing several scenes of a floor simultaneously.

27 PART 2: ENHANCED FEATURES 27/140 Selecting a desired lamp is very simple with ReluxNet. Simply by making a rough selection of the product criteria (lighting system, lamp, sensor manufacturers, interior lights, etc.) you will receive initial suggestions through ReluxNet (Fig. 35). You can fine tune this choice by other criteria (type of mounting, shape, type of lamp, ballast devices, sockets, etc.) until you narrow down to a small selection of lamps which match your requirements. Fig. 35 Fig. 36 Relux Informatik AG, Fit for ReluxSuite 2015,

28 PART 2: ENHANCED FEATURES 28/140 You can check the photometric properties of these lamps directly in ReluxNet and create a first calculation of light.

Just click a view and learn more about the lamps used. Fig. 46 Lamps in application 4.2 Move or rotate objects in a new way General: moving and rotating objects works consistently in the same way in both the floor plan and the 3D view. These commands have been refined for the movement or rotation of objects in the 3D view as of ReluxPro Fig. 47: Shows a selected cube in a scene Relux Informatik AG, Fit for ReluxSuite 2015,

34 PART 2: ENHANCED FEATURES 34/140 Fig. 48 Selected cube with activated handle Fig. 49 Cube with the active handle moved 0.5 m in the z-direction. Basic operation move and rotate in the toolbar. Relux Informatik AG, Fit for ReluxSuite 2015,

35 PART 2: ENHANCED FEATURES 35/140 Just click on an object in your current scene to select it (Fig. 47). As soon as the mouse pointer approaches the coordinate system (the x, y and z-axis as well as the square areas between the axes), its initial colour changes to yellow. (Fig. 48). The colour of the handle will change from yellow to orange, and you can move the object around without keeping the left mouse button pressed (Fig. 49). Press "Esc" to leave this command. The advantages are as follows: The movements of objects are more convenient without keeping the left mouse button pressed. During this movement operation for the objects it is possible to change settings such as the placing grid, etc. An operation can be started in one window (e.g. floor plan) and finished in another window (e.g. 3D view). The viewpoint can be changed during this operation (you can rotate, pan and zoom the view). Move, rotate and scale are the most important operations for constructing a scene. You will find them in the menu bar under Tools and in the toolbar. They all have special handles and a specific mouse pointer which you can see in Fig. 50. From left to right: move object, rotate object, scale object. Fig. 50 Handles and cursors for certain operations (photomontage). From left to right: move object, rotate object, scale object. Relux Informatik AG, Fit for ReluxSuite 2015,

36 PART 2: ENHANCED FEATURES 36/ Move and rotate working plane The working plane can be moved and rotated like any other object in the scene. You can start these operations with the menu Tools - working plane. From here, choose either move or rotate. The handles, which you see afterwards, belong to the working plane (Fig. 51 Fig. 53). Fig. 51 Original position Fig. 52 New position Fig. 53After rotation Relux Informatik AG, Fit for ReluxSuite 2015,

37 PART 2: ENHANCED FEATURES 37/ Edit and draw objects in the 3D view The rotated working plane can now be used for drawing an object, such as a staircase, for instance. After setting an appropriate placing grid - use the raster properties icon - start with the design of a staircase using the command draw a cube with the mouse. Fig. 54 Draw object in the 3D view Each mouse click on your working plane creates a new point. After you have defined the last point, terminate with return or double click the last point. To exit the edit mode, press ESC. Note: during the draw cube with the mouse command, you can undo wrong entries with backspace. Enter your input with return or double-click the last point. Relux Informatik AG, Fit for ReluxSuite 2015,

38 PART 2: ENHANCED FEATURES 38/ Centre luminaire groups To be able to centre luminaire groups within Relux scenes you just need to rightclick the desired luminaire group in the Scene menu. The context menu appears (cf. Fig. 55), and you can select the Centre command to apply the function. Note: You can easily apply the Centre command to other object groups (e.g. groups of furniture, groups of basic objects, etc.) as well as individual objects. Fig. 55: Command: centre luminaire groups Fig. 56: Luminaire group in centre after use Relux Informatik AG, Fit for ReluxSuite 2015,

39 PART 2: ENHANCED FEATURES 39/ Align objects to external walls Move an object onto a rectangular wall and see how the object rotates around its lengthwise axis so that it is always parallel to the wall (Fig. 57). Fig. 57 Align objects to external walls If you want to repeat this command, please select the object and, after you have moved the mouse pointer to the small black cube of the coordinate system, its initial colour changes to yellow. Keep the left mouse button pressed and align the object to an external wall of your choice (Fig Fig. 59). Fig. 58 Selected object Fig. 59 Click the black cube: its initial colour changes to yellow. Relux Informatik AG, Fit for ReluxSuite 2015,

40 PART 2: ENHANCED FEATURES 40/140 Fig. 60 Keep the left mouse button pressed and align the object Whether the object turns the right way or not will depend on where the origin point and the object axis of the object are defined. Click on the object, press the right mouse button and select Use object axis. If the zero point is on the rear side and the Y-axis is parallel to that part of the object, as it should be, then there will be no problem. Fig. 61 Object axis related to the scene Fig. 62 Press the right mouse button Fig. 63 and select Use object axis Relux Informatik AG, Fit for ReluxSuite 2015,

41 PART 2: ENHANCED FEATURES 41/140 Note: The automatic object rotation works for all objects in 2D and 3D. You can move objects along rectangular external walls using the object axis. 4.7 Modification of insertion points From now on it is very easy to change the insert point of 3D objects. This can be done by select an object (except manufacturer s 3D luminaires, or 3D furniture), open the context menu via right mouse click and select the option edit insertion point. Another option is to select the same command from the fly-out Tools menu. Fig. 64 Select the object of your choice and click the right mouse button 4.8 Multiple insert function If you want to insert an object into your scene from the objects and control panel you have two options: Use the drag and drop function to insert an object from the objects and control panel into your scene as usual (as of Version ). Click once on the object of your choice in the objects and control panel. Now you ve entered the multiple insert function mode. You can click onto the 3D view as well as the floor plan as often as you wish to insert the object. Exit this command with ESC. Relux Informatik AG, Fit for ReluxSuite 2015,

43 PART 2: ENHANCED FEATURES 43/ Placing grid/ raster snap There are two different snap functionalities. The first is for a typical Relux scene, and the second for imported CAD drawings. Here we will consider the typical Relux scene (for CAD snap mode please see capture "CAD Import ). The icons in the toolbar are: switch the view of the snap grid on and off. snap onto the crossing points (standard). raster properties: change the grid size, snap into the center, etc. snap into the center (you ll find it in the menu raster properties). The center snap option in the raster properties menu is very helpful for recessed mounted luminaires in certain ceiling systems. You can use the above-mentioned icon for this. To change the grid size, for instance, open the Raster properties menu. Fig. 66 Centered grid on the floor plan Relux Informatik AG, Fit for ReluxSuite 2015,

44 PART 2: ENHANCED FEATURES 44/ Move and scale room elements From now on, room elements, such as windows, doors and pictures, can be selected directly on the wall and moved afterwards (Fig. 67). Fig. 67 Their size can be changed as well (Fig. 68). Fig. 68 To change a dimension, click on the red point and move the mouse. To move the wall element, use an axis (X, or Y) or the square area between the X- and Y-axes, like all Relux Objects. If you would like to move the wall element from one wall to another wall, click on the black cube and press the left mouse button while moving it. Relux Informatik AG, Fit for ReluxSuite 2015,

45 PART 2: ENHANCED FEATURES 45/ Boolean operations on design elements Relux is offering new options for modelling 3D objects. Closed solid bodies (Relux cuboids and 3D objects) can now be subtracted from each other, united or intersected. This then opens up a large number of new options for designing the scene Boolean objects The following operations have been implemented in Relux Difference: one or more objects are subtracted from an initial object. This can be used to punch a hole in an object, for example. Union: a number of objects are combined to form a new object. This can be used to avoid penetrations, for example. Intersection: a number of objects are intersected so that the only volume that remains is that which is enclosed by all the objects in question. This can be used, for instance, to create a new shape from different existing shapes Generating Boolean objects To generate a Boolean object, it is necessary to select the objects involved and then select the desired operation via the context menu (right click in the 3D/2D view, right click in the scene tree) or the main menu (Edit Create Boolean group). Fig. 69 Fig. 70 If the objects are closed and thus suitable for a Boolean operation, they will be included in the operation. Objects with openings will be ignored during Boolean operations. The Relux scene tree then shows the generated Boolean object as a group. The operand geometries are sub-objects of the Boolean object (Fig.70). In the example of a difference (Fig. 69) the sequence inside the Boolean group is decisive. The first object is the original object and all further objects are subtracted from Relux Informatik AG, Fit for ReluxSuite 2015,

46 PART 2: ENHANCED FEATURES 46/140 this. Boolean groups or parameterised groups (field, strip, circle) can also be fitted into each other Editing Boolean objects The Boolean object can still be edited after it has been created. To do this, you should click on one of the operand objects in the scene tree and edit it via the property window or in the 2D/3D view Parameterising and positioning of operand objects In the current example in Fig. 71, a cuboid defined as round was subtracted from a rectangular cuboid. If you want to change the cylinder afterwards, then you should select this in the scene tree. If a sub-object of a Boolean group is selected, then the operand objects are shown in addition to the generated object (in this case the cuboid with the hole). The selected object is coloured orange and the non-selected ones cyan. Fig. 71 Editing objects inside a Boolean group Relux Informatik AG, Fit for ReluxSuite 2015,

47 PART 2: ENHANCED FEATURES 47/140 The Boolean object generated from a rectangular and a round cuboid. Select the round cuboid. The cuboid selected is orange and ready for editing. Change the radius of the round cuboid. Move the round cuboid. Deselect the object. The function of interactive duplication keeping the CRTL key pressed can also be applied inside Boolean groups. In the example in Fig. 71, additional holes could be punched out of the rectangular cuboid by moving them while keeping the CTRL key pressed Sequence of operand objects As already mentioned in Chapter , the sequence of the operand objects within the Boolean group may be decisive. This is the case, for instance, if objects are to be subtracted from each other (creation of a difference). Which object is to be subtracted from which other one is important here (A-B B-A). The sequence can be subsequently altered via the scene tree. To do this, click on the object whose position is to be changed and, keeping the left mouse button pressed, move it to the desired position. If it is moved to the group node of the Boolean object, it will fall out of the group, or alternatively fall into it, depending on whether it was already in the group or not i. The example in Fig. 40 shows how the corner of a cube is to be cut off by a second cube. The initial intention was to cut off the top corner of the lower cube with the bottom corner of the upper cube. The group was generated in the wrong sequence, however. In order to change this sequence, you should proceed as follows: Relux Informatik AG, Fit for ReluxSuite 2015,

48 PART 2: ENHANCED FEATURES 48/140 Fig. 72 Changing the sequence in a Boolean group The object generated the wrong way: the lower cube is subtracted from the upper cube. Select the upper cuboid in the scene tree (first sub-object in the Boolean group). Keeping the left mouse key pressed, move the upper cube (sub-object 1 in the scene tree) on to the lower cube (sub-object 2 in the scene tree) or the other way round. Let go of the mouse key (drag and drop). Deselect the object Defining the materials of the Boolean object When a Boolean object is generated, new surfaces are created. These surfaces are always in the same material as the surface from which they have been created. If red cuboids are punched out of a grey cuboid, for example, the outside surface of the generated object will be grey and its holes red. If the partial surfaces of the Boolean objects are to subsequently be given a different colour, this can be done by editing the operand objects in the property window or by pulling a material onto the operand object by drag and drop. To do this, the operand object must, however, have been selected beforehand (Fig. 73). Relux Informatik AG, Fit for ReluxSuite 2015,

49 PART 2: ENHANCED FEATURES 49/140 Fig. 73 Subtraction of objects with different materials Original objects. Red cubes are subtracted from the grey cuboid Incorporating a Boolean object in the 3D library Once a Boolean body is finished, it can be incorporated in the library of 3D objects. This will enable it to be positioned in additional scenes in the same way as all other library objects. It must, however, be borne in mind that the Boolean group can then no longer be edited. Holes that have been generated cannot be moved any more or have their dimensions changed. The command to perform this is "Convert to 3D object" and it can be called up with a right click via the context menu. Once the command has been executed, the object will be found in the library (left side of Relux Objects 3D Objects / Furniture).

50 PART 2: ENHANCED FEATURES 50/ Examples The following chapter shows a few sample applications for a number of simple Boolean operations Difference: holes in a partition wall An indoor room is to be modelled, which is divided up into two offices and a corridor by means of partition walls. The offices are to be accessible from the corridor through an opening. One of the offices is additionally to have a hatch between the office and the corridor for serving customers. Fig. 75 Example of cut-outs in a partition wall Model the partition wall and the cut-outs in the wall in the form of Relux partitions and Relux cuboids. Create the Boolean difference between the partition wall and the cut-outs in the wall. Relux Informatik AG, Fit for ReluxSuite 2015,

51 PART 2: ENHANCED FEATURES 51/ Union/difference: facade A facade with windows is to be modelled for an outdoor view. The windows are halfrounded. The frames on the outside and the window sill are to be taken into account too. Fig. 76 shows one possible way of doing this. Use is made of nested Boolean groups in order to implement the final result. On the inside, this is a union (wall with frames and their window sills). Holes for the window openings are subtracted from these. Fig. 76 Example of modelling a facade Modelling the wall and an individual window frame. Rectangular cuboid for the wall. Rectangular cuboid for the window sill (blue). Rectangular cuboid for the window frame at the side (green). Round cuboid for the window frame at the top (blue). Convert into a polygonal cuboid and scale in the y direction. Delete the superfluous points at the bottom. Group together the cuboids for the window frame and the window sill in a free group and duplicate as a field (5x5). Relux Informatik AG, Fit for ReluxSuite 2015,

52 PART 2: ENHANCED FEATURES 52/140 Form the Boolean union between the wall and the group (window frame and window sills). Generate the same cuboids again as those that were modelled for the window frames under Point "1" above, but without the window sill. This time, however, reduced by twice the thickness of the window frame (for the window cut-out). Group together the cuboids generated under Point "4" above in a free group and duplicate as a field (5x5) window cut-outs. Generate the Boolean difference between the union generated under Point "3" above and the window cut-outs (Point "5") Intersection: lentil A lentil or a discus as it is known in athletics is to be modelled. The lateral surfaces of the discus are to be flattened so that they end in a blunt edge. To do this, we use a Boolean intersection of three objects. The objects required are two compressed spheres and a cylinder. Fig. 77 Example of modelling a discus Position a compressed sphere. Duplicate the sphere positioned under "1" and shift it sideways. Position a round cylinder (rotated 90 around the x-axis). Generate a Boolean intersection between all three objects. Relux Informatik AG, Fit for ReluxSuite 2015,

53 PART 2: ENHANCED FEATURES 53/ New Basic Objects Additional basic objects have been added to Relux to enable more elaborate objects to be modelled. All the new objects are rotational solids. The angle through which they are rotated (0 < angle 360 ) and the number of segments generated can be specified for all the rotational solids. The object height is a further parameter that can be set. The object can be made of one or more materials depending on the object type. Sphere: the sphere is made up of a single material. In addition to the number of segments, it is also possible to specify the number of layers here. A texture is adapted by means of sphere mapping. Hemisphere: the hemisphere can be made up of two different materials one for the upper hemisphere and one for the base surface. In addition to the number of segments, it is also possible to specify the number of layers here too. A texture on the hemisphere can be adapted by means of sphere mapping, and a texture on the base surface by means of cuboid mapping. Cone/truncated cone/pyramid/truncated pyramid: in the case of a cone, a radius can be specified for the base and a radius for the top. If the radius for the top is greater than 0, this is a truncated cone. If a value of 4 is selected for the number of segments, a pyramid or a truncated pyramid will be generated. The cone is made up of a maximum of three different materials: the outside surface and the base and top surface. A texture on the outside can be adapted by means of cylinder mapping and a texture on the base and top surface by means of cuboid mapping. Ring: the ring is parameterised by means of four radii: the inside radius at the top and the bottom and the outside radius at the top and the bottom. In this way, it is possible to model conical pipes too. Polygonal rotational objects: in addition to the fixed parameterised rotational objects mentioned above, the rotational solid can also be polygonal. To generate solids of this type, you use the "Construct rotational solid" tool under "Tools" "Construct" "Rotational solid". The polygonal rotational body is made of just one material. When it is generated, there are fundamentally two different ways in which a rotational solid can be created: Rotation around an axis: first of all, you draw the axis around which the closed polygon is to be rotated. Following this, the rotating polygon is drawn in (this is not permitted to intersect the axis of rotation). The action is completed with a double click or by pressing the enter key. Rotation around the end points: after selecting the "Construct rotational solid" tool, press the enter key to skip the step for drawing the axis of rotation. The polygon that has been generated can be rotated around its end points by a double click or by pressing the enter key on the keyboard again. What is important here is that the polygon should not intersect its axis of rotation that is defined by its end points. Relux Informatik AG, Fit for ReluxSuite 2015,

54 PART 2: ENHANCED FEATURES 54/ Polygonal Window and Window Frames The existing room elements for indoor rooms (windows, skylights, doors and pictures) have been extended and enhanced. This section describes the points that have been implemented here New shapes Windows and doors, etc. have traditionally been defined by their length and width in Relux, i.e. they have been rectangular. These shapes have been extended by circular, semi-circular and polygonal shapes. Figure 78 shows the new shapes that are now possible. Fig. 78: From left to right: rectangular-, circular-, semi-circular-, polygonal windows Additional geometry Well-versed Relux users will be familiar with the option of adding window frames and window sills, etc. from our raytracing engine. The raytracer has been capable of calculating an additional geometry for a long time. This additional geometry can fundamentally now be used in Relux as well. It can be accessed and adjusted via the property window for the room element in question. Relux Informatik AG, Fit for ReluxSuite 2015,

55 PART 2: ENHANCED FEATURES 55/140 Fig. 79 and Fig. 80: Settings for the additional geometry of a window The geometry of the frame can be edited via the properties window for the windows, doors, or pictures and relates to all the geometries which point to the same reference. This additional geometry is comparable with a library object. It is naturally still possible to administer a number of different additional geometries. If a window has an additional geometry, then the window-bar factor is superfluous, since the bars are already taken into account in the calculation through the additional geometry. For this reason, this factor is set on 1.0 if an additional geometry is allocated to the window and is blocked in the dialogue (Fig. 79) Rotation of the wall objects With skylights, in particular, planners would frequently like to be able to rotate these around their z-axis. This can now be done via the dialogue or interactively in the 2D/3D view Depiction of a realistic wall jamb The window is now placed in the middle of the wall. The thickness of the walls and ceilings and hence the position of the window can be set via "Extras > Options > Outdoor room This gives rise to a wall jamb on both the inside and the outside wall. The material for the jamb is identical to the material for the inside or outside wall. Relux Informatik AG, Fit for ReluxSuite 2015,

56 PART 2: ENHANCED FEATURES 56/ Design of wall elements / drawing windows Polygonal windows and doors can also be constructed or drawn interactively on the screen using the mouse. To do this, you should select the tool for constructing windows via "Tools" "Construct" "Window" or the "Tools" toolbar ( then proceed as follows: Activate the "Construct window" tool. ). You should Select a wall on which the window is to be constructed. Via 3D or in the scene tree. Draw the describing polygon on this wall New editing functions In order to make working with Relux even more efficient, 2012 has had different editing options added to it New tool: rotate object uniaxially If an object is to be rotated, this will generally be around a single axis. In many cases, the desired rotation is a rotation around the z-axis. This rotation is generally performed in the floor plan. This is still, of course, possible with the familiar threedimensional rotation. For planners wishing to have precise results, however, it was often faster and more accurate to enter the value in the dialogue via the keyboard. Not least if the rotation was to be based on a line in a CAD plan. The new tool "Rotate object uniaxially" ( ) now also offers the option of interactive use of CAD snap. Using this tool, you take the intermediate angle of the x-axis of the object and a vector by which the object is to be rotated. Fig. 81 shows how a table is lined up with a line in the CAD plan using the "Rotate object uniaxially" tool. If an object is not to be rotated around its origin, a different point of rotation can be set prior to the rotation proper by keeping the Ctrl key pressed. Fig. 82 shows how a luminaire that is placed in the middle of a corridor is lined up to the wall alongside it. Fig. 81 Aligning a table to a CAD line with the aid of the CAD snap Fig. 82 Aligning the luminaire to any desired line on the floor plan Relux Informatik AG, Fit for ReluxSuite 2015,

57 The "Rotate object uniaxially" tool can also be used as a combined tool in conjunction with the "Place object" or "Move object" tool. This can be specified via the tool settings (Tool Settings be set. ). Fig. 83 shows the dialogue in which these options can Fig. 83 Setting the "Rotate object uniaxially" tool as a combined tool Setting this option means that each positioning or moving step is followed by "Rotate object uniaxially". If you wish to skip "Rotate object uniaxially", you can do so by pressing the Esc or Enter key.

58 PART 2: ENHANCED FEATURES 58/ Draw polygonal scenes (interior, exterior) Define a new interior project, or add a new room to your project. Choose a polygonal room shape (Fig. 84). After that dialog, you will be in 2D edit mode, where you can define the room shape and the length of each wall (Fig. 85). You can end this 2D edit mode with a double click or the "ENTER" key. A new menu opens and you can extrude your scene either to the Z-, or X-axis (Fig. 86). This procedure also works for exterior projects (without extrusion of the walls) This option makes it possible to construct rooms both off of a floor plan and from a cross-section. This procedure works both for interior rooms and for outdoor projects (there it is not necessary to extrude the walls). Example 1: extrude scene to Z-axis Fig. 84 Selection of room type Fig. 85 2D edit mode

62 PART 2: ENHANCED FEATURES 62/ CAD import with ReluxPro There are two ways to import CAD files. Option one is to construct a CAD scene from a CAD plan. The second option is to import CAD drawings into existing scenes, see File-Import-CAD Plan Example 1: CAD-Import with ReluxPro (single rooms) The new ReluxPro offers two different possibilities of importing CAD files (of *.dwg/*.dxf formats). The first option involves selecting the CAD Import option in the Start menu of ReluxPro and to design a new scene using an imported CAD Plan. The second option is to import a CAD file into an existing scene. Follow the Menu File Import CAD-Plan. Example 1: Create a new scene using a CAD-Plan Fig. 93 Start menu CAD-Import In general the following applies: The new powerful CAD interface allows you to import any *.dwg or *.dxf file format data in a few steps. Click the option CAD-Import and follow these seven steps: Step 1: Enter project data Step 2: Set the type of project (interior/exterior installation) (Fig. 95) Step 3 (for interior projects only): Specify the type of interior project (single room/floor) (Fig. 96) Step 4: Select a file (*.dwg or *.dxf) Step 4: Set the scale (often 1000/m for interior and 1/m for exterior installations) Step 5: Rotate the drawing (requires knowledge of drawing, otherwise continue) Step 6: Set the origin (requires knowledge of drawing, otherwise continue) Step 7: Capture the actual Relux scene

82 PART 2: ENHANCED FEATURES 82/140 Fig gbxml-import with ReluxPro The Green Building XML format (gbxml) has been designed as an open data format. GbXML allows you to easily transfer building data (building hierarchy, geometry, daylight openings, doors, etc.) from Building Information Models (BIM) to engineering or analysis software. Currently, GbXML is being integrated into a variety of CAD programs and Engineering Tools and supported by leading 3D BIM vendors. The new ReluxPro provides, like the CAD Import - two different possibilities of importing gbxml files. The first option involves selecting the option Project Import in the Start menu of ReluxPro and creating several new scenes using an imported gbxml file. In this, any existing doors or windows are placed at the same time. The second option is to import more gbxml data into an existing project. Follow the Menu File Import Scene.

90 PART 2: ENHANCED FEATURES 90/ ReluxMovie Module Fig Introduction Films can be generated in a particularly easy manner with the animation module in ReluxPro (Fig. 150). For this, you simply require the Animation toolbar and the animation bar. You can have these displayed or hidden via the Window-Animation Bar and Window-Symbol Bar-Animation menus. The procedure for compiling an animation has already been described in the New ReluxMovie Module section, which is why we are now setting out the details of these new options Animation bar Fig. 144: Animation toolbar

91 PART 2: ENHANCED FEATURES 91/140 When a new camera position is set, the position of the camera on the time axis is established automatically on the basis of the specified speed. The positions are shown on the time axis with the symbol. The positions on the time axis can be changed manually. To do this, you should move the controller (black bar), either with the mouse or with the command, until it is close to a camera position and this changes its colour to red. Keeping the Ctrl key and the left mouse button pressed in the black area, you can now move the camera position on the time axis. If you additionally press Shift, all the subsequent camera positions will similarly be moved. A new camera position on the time axis will overwrite an existing camera position. The duration of an animation is automatically set at 30 seconds. This can be changed in the properties of the animation in question. There are two ways of showing the time: the number of pictures (1 B., 2 B., ) or in hours, minutes and seconds (hh:mm:ss:ff, SMPTE timecode). The setting for this can be made under the Extras Options General Settings menu, under the Animation units in SMPTE Timecode option Maintaining the observer height In order to maintain the observer height when the different camera positions are set, a useful key shortcut has been introduced for operation via the mouse and the keyboard. As long as you keep the Alt key pressed, the current observer height will be maintained. Maintaining the observer height when moving Alt and rotating in the 3D View Animation path In the 2D and 3D View, the trajectory of the camera between the individual camera positions is shown as a dotted blue/orange path. Each section of line represents a picture. In the Floor Plan View and all other 3D Views, the camera travels along this path when the animation is played. By clicking on the path, the individual camera positions are shown as blue squares. These squares can be selected and the camera position changed or deleted. An animation path of this type can be copied, moved and rotated in the same way as an object.

92 PART 2: ENHANCED FEATURES 92/140 Fig. 145 Animation path Multiple animation paths The program allows more than one animation to be conducted within a scene. When you click on one of the camera positions (blue squares) in the 3D View, Relux shows one or other of the animation paths in the Animation toolbar. The 3D camera symbol is shown in red if the associated animation is active. For nonactive animations, the 3D camera symbols are shown with blue lines. These are red if the animation is active Interpolation Between the camera positions, the path that the camera follows is set automatically. By way of a default, the Akima interpolation is used for the path. This interpolation can also be switched. To do this, select one of the three interpolation functions in the context menu for the animation node in the scene tree: Linear: Fig. 146 Linear interpolation

93 PART 2: ENHANCED FEATURES 93/140 The simplest type of interpolation. This connects points by means of a line. The values between the points are established on a linear basis. This generally causes a jolt at the point where the photo is taken. Cubic: Fig. 147 Cubic interpolation This interpolation leads to a soft curve between the points. It guarantees a smooth and jolt-free profile. There can, however, be considerable deviations from the direct link between the photo points. Akima: Fig. 148 Akima interpolation This interpolation type similarly creates a soft curve between the points. The Akima curve remains closer to the direct link, however, than the cubic interpolation Stretch-compress animation If you have compiled an animation and wish to compress or lengthen the playing speed of a film, you can select the Stretch-compress function in the context menu for the animation. In the subsequent dialog, you can specify the length in seconds to which the animation is to be stretched or compressed. The animation cannot be compressed so far that the individual photo points overlap. Fig. 149 Stretch animation

94 PART 2: ENHANCED FEATURES 94/ Animation properties By double-clicking on the animation node in the project tree or clicking on the Animation toolbar, you can call up the property window for this animation. The following settings can be made via the dialog (5): Fig. 150 Animation settings Frame rate: defines the number of frames per second of film. Time axis: defines the range that is shown in the animation axis; this can be specified by setting the time to be shown in seconds or the number of pictures Rendering the animation An animation path must be rendered beforehand for the film to be obtained. To do this, select the icon with the film slate-board in the toolbar or select the Extras render animation option. The following dialog can be used to make settings for the format and resolution (Fig. 151, Render settings). Fig. 151 Render settings Output type: here the user determines the output type with which the film is to be generated. It is possible to choose between Uncalculated, i.e. the normal 3D View, or Luminance distribution i.e. the calculated 3D View. At the moment, calculated radiosity scenes can be rendered by this method but not raytracing scenes.

95 PART 2: ENHANCED FEATURES 95/140 Format: Defines the output format for the film. With the AVI option, the film is calculated in the standard format used for Windows. By clicking on Options, it is possible to select a codec that is available on the computer and also the desired compression stage. As a further option, the film can also be saved as a series of individual pictures, and it is also possible to choose between JPEG and BMP. Resolution: The most common film formats are listed in the selection box. You can also specify the film resolution that you would like via the input fields (width and height). Duration: Here you decide which part of the animation is to be saved in the film. You can choose either All pictures or just Current picture. With the input fields of from / to, you can limit the animation to a duration that you select yourself. By clicking on Start you call up a dialog which asks you where the target file is to be written to. The user s video folder is set as the default (My files/my videos). After confirming with OK, the rendering process will be started automatically (Fig. 159). Fig. 152 Render manager The Render manager shows the following information: Number of pictures calculated / Total number of pictures Time elapsed since the start of the rendering process Time remaining until the process is completed Estimated overall time for the compilation process

96 PART 2: ENHANCED FEATURES 96/140 Path for the film being calculated The checkbox can be used to show or switch off a preview. The preview shows which individual pictures are being written to the film. The process can be stopped at any time in order to eliminate any setting errors. If the film is to be shown in the Standard Player once the rendering is complete, the Open after calculation box must be checked. Note: It is not possible to continue a rendering process that has been interrupted. The film is not saved in the Relux project file but in a separate file.

97 PART 2: ENHANCED FEATURES 97/ New GR and TI glare rating for outdoors The glare rating in outdoor projects has been extended in the Calculation manager. Under Artificial light and the Glare rating tab, new GR and TI glare ratings can be calculated for observers. The following description explicitly covers the verification required by the German Railway (DB) for overground platforms. Fig. 153 Calculation manager dialog What is calculated? The direct light from each individual luminaire is calculated at each observer point. This value, set out as a ratio to the surrounding luminance, gives the GR or TI value. The surrounding luminance value is obtained as a function of the defined measurement area, referred to as the reference value. Although this is an approximation, CIE 112 stipulates that it is a permitted approximation. GR values stand for stationary observer points and TI values for travelling or moving observer points.

98 PART 2: ENHANCED FEATURES 98/ Measuring area and observers See Point 1, Fig To calculate the GR value and the TI values, the program requires a Reference area for establishing the surrounding luminances. The Reference area must be allocated a mean Reflectance of the real area that is positioned underneath it. The program looks for this reflectance automatically. This procedure, as described, makes it possible to establish the GR / TI for any desired scenes and at different levels. Note: Try to avoid dissimilar reflections beneath reference surfaces if possible. If the reflectance of these real surfaces (e.g. the floor) changes, it may be necessary to adjust the reflectance of the reference surface. 2 1 Fig. 154 Measurement or reference area See the above Figure. The observer points arranged like a table represent the waiting passengers next to the railway lines; the observer points arranged in a row represent the driver of the train that is arriving. The position and size of the reference area ought always to be selected to suit the requirements (sports ground, station platform...). In the picture above you can see the reference area shown in red. Care was taken to ensure that this is lined up in parallel beneath a repeated pattern of positioned luminaires. The program positions a group of 5x5 observers uniformly in front of the reference area for calculating the GR values. The observer points for the vehicle driver are positioned in parallel to the reference surface. The first observer point is at an angle of 20 prior to the first luminaire above

99 PART 2: ENHANCED FEATURES 99/140 the reference surface. In the transverse direction, it is placed 1.66m alongside the left edge of the measurement field (platform edge). The number of steps and the distance between them is governed by the length of the measuring surface and the number of measuring points set. The basic parameters are set in accordance with the German Railway (DB) Guidelines. All the parameters can be adjusted as required. Note: The observer points are not updated automatically. If the observers have to be realigned due to changes in the luminaire positions or the alignment of the measurement surface, you must trigger the automatic positioning of the observer points manually. To do this, go to the Calculation Manager and start DB Guidelines again. Please note that when GR and TI values are determined for outdoors, all the light reflections are calculated as in the past, but, according to the method proposed in CIE 112 for determining the mean background luminance, only the reference surface is taken into account. A bright white wall directly in the observer s field of vision thus only has an indirect influence on the mean background luminance. As a result, the calculated GR and TI values tend to be too high (see CIE112). On the other hand, it is not necessary to recreate every 3D detail in outdoor projects.

100 PART 2: ENHANCED FEATURES 100/ Raytracing calculation in Relux Pro How to use the Relux raytracing calculation Fig. 155 Fig. 156 The raytracing calculation is based on a version of Radiance that has been revised by Relux. This verified method, which has been validated worldwide, is noted for its accurate calculation results. A ray tracer is a complex tool with many adjustable parameters which need to be set by the user. To use the raytracing calculation, just open the calculation manager of ReluxPro. (Fig ) Note: The following chapter provides a short introduction to the use of this calculation method. For more detailed information please refer to our newly completed guide "Radiance calculation with ReluxPro". You will find this additional guide either on our ReluxSuite DVD, or on our website at Relux Raytracer offers two modes for doing calculations: in the standard mode the most important parameters are set automatically depending on the chosen quality setting, only the number of diffuse interreflexions can be specified separately. For normal scenes, these automatic settings deliver very good results already, with acceptable calculation times. For specific demands, Relux Raytracer additionally offers an expert mode, which makes it possible to control the execution of the program separately for the different individual tasks of a lighting simulation, like the direct or indirect part of the illumination calculation, or special adjustments for daylight scenes, etc. Note: Both modes are independent. This then offers the option of setting low quality values in the standard mode for quick preview renderings in the chosen image

101 PART 2: ENHANCED FEATURES 101/140 format and, at the same time, setting high quality values in the expert mode dialog. Afterwards, one can easily switch between the two approaches by simply activating / deactivating the expert mode. Fig. 157 ReluxPro raytracing calculation

102 PART 2: ENHANCED FEATURES 102/ The Standard mode parameters The preparations for a visualization with the "Raytracing calculation" take in the same steps as those for a standard light calculation in "ReluxPro" (Fehler! Verweisquelle konnte nicht gefunden werden.). 1. Create a new project or add a new scene to your current project 2. Develop the layout of the room with furniture and wall materials, for example 3. For artificial light calculations: select and position the luminaires of your choice and for daylight calculations: select and position at least one window or a skylight Fig. 158 Calculation manager (Standard mode)

103 PART 2: ENHANCED FEATURES 103/140 Once the layout of the scene has been completed, you can go further and open the calculation manager. Further inputs are required here, in the same way as for the standard light calculations. The calculation manager incorporates a switch box to activate the Radiance parameters. Let us first cover the standard settings, starting with the type of calculation: Type of lighting Artificial light Daylight Only Artificial light and daylight Only luminaires are calculated as light sources Windows are depicted as black surfaces (night). The light coming through windows and skylights is calculated. All artificial light sources and daylight are taken into account. Next, you ll find the settings for the daylight calculations with the different sky conditions, together with the date and true local time. The time is converted and also shown as so-called "true solar time (TST)" using the date and the longitude entered in "Project - Location". This essentially determines the position of the sun and therefore the luminance distribution of the sky. If required, you can set the switch button "with sun" to calculate the effect of direct sunlight as well. Sky type Clear sky according to CIE Intermediate sky according to CIE Overcast sky to CIE Only the radiation of the sky is taken into account, without the radiation due to the sun. CIE Publication No. 22 of 1973 A partially overcast sky with the components of overcast and clear sky being determined on the basis of the sun probability and additional weighting factors. CIE Publication No. 22 of 1973 The CIE defines an overcast sky with an uneven light distribution here, deviating slightly from DIN 5034 Part 2. CIE Publication No. 22 of 1973 Uniformly overcast sky This sky type has been described in DIN 5034 Part 2 with a specific luminance for all directions, i.e. determined solely by the angle of the point in the sky to the zenith. In the standard mode you can also set the image quality as well the number of "Interreflections". The best possible quality of renderings is achieved with "high". In the Expert mode, a lot more settings are additionally available. This document contains only a summary. Note: For more detailed information please refer to our newly completed guide "Radiance calculation with ReluxPro". You will find this additional guide either on our ReluxSuite DVD, or on our website at

104 PART 2: ENHANCED FEATURES 104/ The Expert mode parameters Fig. 159 Fig. 160 Expert mode The justification for having several parameters is that the program aims to offer the possibility of adjustment for all kinds of specific scenarios. In general, only a few of the values will need to be changed by the user, as a function of the project. In what follows, a number of guidelines are set out to provide you with the necessary background for performing the appropriate parameter adjustment. (Fig ) Note: the option of changing individual parameter settings is provided as a convience but also constitutes a challenge. It is, of course, vital to have consistent value settings. If a high image quality is chosen and at the same time an insufficient spatial resolution is set for the indirect light calculation, the results will most probably not be satisfactory.

105 PART 2: ENHANCED FEATURES 105/140 Scene geometry: Parameters in this category do not generally require user intervention, since they are only provided for very exceptional cases in which problems occur with exporting the geometry. For the raytracing process, the scene data are converted into a special structure (octree). The scene is subsequently divided into cubes and sub-cubes to provide information on which parts of the overall volume are occupied by objects and which not. An important criterion for this conversion process is, of course, the ratio of the smallest featured geometry size to the overall scene size. The underlying algorithm is already capable of handling a wide range of geometry ratios, however, so the octree resolution does not normally need to be changed. Only in cases in which huge scenes also contain a lot of small geometric detail, especially if this detail appears in a locally concentrated manner, might it be necessary to augment this value (e.g. from to 32000). A further geometry-specific adjustment option affects the way in which the objects are stored internally. Given the fact that scenes are generally growing more complex from year to year, Relux Raytracer allocates all the objects a highly compressed data structure by default. Thus, scenes can be rendered now with the new version which were an impossible task for previous Relux Raytracer versions. This memory optimization does not normally need to be changed by the user. (For simple scenes, deactivating it can save around 10% of the calculation time) Image Quality: For convenience, some parameters are still subsumed under the category of image quality even in expert mode. Apart from a number of internal calculation parameters, this value also controls the over-sampling rate and the image filtering, which is applied to smooth out rough borders and pixel effects in the final image. Direct Illumination: With regard to the direct part of the overall illumination calculation, the options soft shadows and the associated value of the source subdirelux Raytracer amount are currently adjustable by the user. For a realistic image appearance, the soft shadows option should remain activated. The subdirelux Raytracer parameter then determines how softly the shadows are to be rendered. A higher value for the subdirelux Raytracer unfortunately also results in an increase in the necessary calculation time. Indirect Illumination: Calculating the indirect part of the illumination is undoubtedly the most complex task of a visualization. Within Radiance, the indirect illumination is also simulated with a ray tracing process, but in contrast to the simple direct ray tracing method, rays are sent out not only from the observer's point of view in this case but also from various points within the overall scene. These indirect rays sample the (indirect) illumination that reaches the point under consideration from the whole hemisphere above it. Benefit is also derived from the fact that the indirect illumination varies much less strongly than the direct illumination. It is thus possible, to a certain extent, to cache values from the calculation and to re-use them for points in the vicinity (interpolation method). This general approach demands a set of specific parameters, of which the four most important ones can be set in Relux Raytracer: The number of interreflexions, i.e. up to which depth indirect interreflexions are followed, the spatial resolution used for the calculation and interpolation process, the number of indirect rays which are sent out to sample the surrounding hemisphere, and, finally, a value for the background ambient illumination, which serves to simu-

106 PART 2: ENHANCED FEATURES 106/140 late the part of the illumination which is not considered due to the fact that only a finite number of indirect interreflexions are traced. Theoretically, an infinite number of interreflexions need to be considered in order to simulate the light flux exchange between the scene surfaces in a physically exact manner. To limit calculation times, especially for visualizations, one can work with just a few interreflexions and simulate the rest with an ambient background light. In this case, 2-3 interreflexions are recommended for practical application in normal scenes. Let us take a simple indirect illumination scenario as an example. With 1 interreflexion, the path luminaire -> ceiling -> workplane is sampled, and with 2 interreflexions additional paths like luminaire -> ceiling -> walls -> workplane can be considered. The ambient illumination is generally scene-dependent; it is advisable to run a number of previews to establish suitable values for typical scenarios. Higher values for the number of interreflexions (3-5) are recommended for scenes with mainly indirect illumination, or if a high calculation accuracy is needed. More than 7-9 interreflexions are generally not advisable, since the sampled contributions decrease quickly with higher iteration levels and, in the end, fall below the general error of the applied stochastic ray tracing method. (It is clear that the ambient light should be reduced accordingly when using such a high number of interreflexions, or set completely at zero, in order to avoid erroneously adding light to the scene.) Of course, the number of indirect interreflexions has a pronounced influence on the calculation time. For quick preview runs, the indirect calculation can be switched off completely (0 interreflexions). Keep in mind that all surfaces which are not illuminated directly by a light source are then rendered unnaturally dark. The necessary spatial resolution is a critical parameter which is very much a function of the scene geometry and leads to artefacts in the image if set to inadequate values. The default value of 0.4 m is already a relatively coarse setting to keep calculation times to within reasonable limits. Scenes with a high illumination variance and/or fine detail might need a finer setting (such as 0.2 or, in extreme cases, as low as 0.1 or 0.05). It should be noted that this, unfortunately, rapidly leads to a considerably higher calculation time. On the other hand, with artificially illuminated exterior areas, for instance, where the indirect component part plays a more minor role, the value can often be increased (to between 0.6 and 1.0 m, for example) without immediately causing image artefacts. The pronounced dependence on the scene geometry and the illumination configuration make it difficult to provide any further general advice. Given the major influence on calculation time, however, it is generally advisable to experiment with different settings. The number of indirect rays is set to a default value which is adequate for standard scene types (please consult the following chart). What has been said above, however, similarly applies here a large amount of scene detail and a high illumination variance could necessitate an adjustment (to between 800 and 1000, or more) in order to make sure that all the surrounding details are correctly sampled. With more or less empty scenes and fairly uniform illumination, the value can safely be reduced (to between 300 and 500, or less). The influence on the calculation time is less pronounced than for the spatial resolution parameter (although 1000 rays might sound a great deal, they still only permit a rather coarse sampling of the surrounding objects). Experimenting with different settings is recommended, too. Hence, in the case of scenes that require a fine spatial resolution on account of extensive geometry detail, but which also have only a low illumination variance, it may make sense to reduce the number of indirect rays so as to keep the calculation times within reasonable limits.

107 PART 2: ENHANCED FEATURES 107/140 Simple scene (artificial and/or daylight with precalculation of daylight openings, such as windows; good, uniform light) More complex scenes (more details; highly varied illumination through the use of narrow beam spots und/or direct sunlight) Calculation of daylight without the precalculation of daylight openings such as windows Daylight calculations Daylight calculations are generally more challenging because of the greater variance of the illumination (by comparison to artificially lit scenes). Another difficulty is that the sky hemisphere cannot be treated as a localized light emitter in the same way as a normal luminaire. For this reason, the sky portion of the illumination is evaluated using the indirect light process in Radiance. (By contrast to the sun itself, which similarly cannot be localized because of its great distance, but which can easily be simulated as an angular light source with a source angle of approximately 0.5 ). To accurately simulate the illumination through daylight openings, it is recommended that a precalculation be run for all the openings (windows and skylights). Each daylight opening is treated separately, and a luminous intensity distribution is generated which describes the angular dependence of the incoming daylight, making allowance for the chosen sky model and all the external obstructions (if modelled). It is, of course, necessary for the level of the external interreflections to be correctly specified. The default (and minimum) value of 1 for the interreflection only takes the sky itself into consideration. All the geometry objects outside the room act as pure obstructions. With 2 or more interreflections, it is possible to additionally consider the amount of light (from the sun and the sky) which is reflected by external objects. The precalculation routine thus converts daylight openings into localized light sources, making for a more accurate calculation by comparison to a simulation that uses the indirect algorithm for simulating the room as a whole. These localized sources can, however, produce disturbing highlights in conjunction with reflecting surfaces when images are generated. It is thus possible for this precalculation to be switched off. In this case, it is recommended that the number of interreflections be increased to 3-5 or more (both the interreflections within the room and those outside it must now be considered together). The number of indirect rays can perhaps also be increased (e.g. to or more). Switching off the window precalculation can also make sense for scenes with very large daylight openings, e.g. rooms with large window sections that cover entire walls from floor to ceiling.

It also offers facilities for defining additional views and entering the settings for the size of the visualizations. A preview button is provided for the creation of previews Raster measuring areas and start of calculation The Relux raytracing module has a "Raster measuring areas" dialog (Fig. 169) for calculating luminances or illuminances. This dialog is used in the same way as in Relux- Pro calculations.

110 PART 2: ENHANCED FEATURES 110/ ReluxVivaldi Calculation Fig. 163 ReluxVivaldi is a module for dynamic light simulations based on precalculated HDR images (Fig. 163). When a scene with several luminaires is calculated separately on the basis of control groups, in which there is only one group of luminaires switched on for each individual calculation, HDR images can be added afterwards with different scale factors. This can almost be done in real-time since the time-consuming Raytracing calculation has been performed beforehand. Thus, dynamic light control can easily be simulated in the same way as if the luminaire groups were actually to be dimmed. Of course, daylight can be incorporated into the process, such as by a sequence of calculations for certain time and state of the sky. An important additional aspect is that the ReluxVivaldi simulation includes energy information in the calculation. That way, the energy consumption of a lighting set can be readily simulated in dynamic operations. It is, for example, possible to determine the energy savings that can be achieved by reducing the use of artificial light on account of there being sufficient daylight.

111 PART 2: ENHANCED FEATURES 111/ Why Relux Vivaldi ReluxVivaldi allows you to visualise dynamic lighting solutions ReluxVivaldi is easy to handle and convincing. ReluxVivaldi presentations include: lighting scenes dynamic changes in lighting (timelines) and energy calculations incl.

The results are saved in compact format in the Relux project file. With this precalculated sequence of images, the actual ReluxVivaldi Module can then be activated for the simulation of different dynamic scenes.

113 PART 2: ENHANCED FEATURES 113/ ReluxVivaldi Calculation In this chapter, the first of two simulation steps, the so-called ReluxVivaldi Calculation will be further explained. The software organizes the necessary multiplecalculations of the scene mostly automatically so that, without much effort, a complete set of HDR images can be created for the following dynamic simulation. The second step the use of the ReluxVivaldi Module is described in a separate document. The adjustments for the ReluxVivaldi calculations can be carried out in the same-titled dialog of the Relux calculation manager. This is structured in the same way as the calculation dialog of the standard Raytracing calculation (cf. Chapter 4.19). The views can also be adjusted in the second View tab, as for an ordinary Raytracing calculation ReluxVivaldi calculation settings The adjustment of the daylight times in ReluxVivaldi is different, though, since several points of time and/or types of sky can be specified (cf ). Furthermore, the ReluxVivaldi main dialog contains a display with information on the number of existing artificial light control groups as well as the configured daylight times. Note: The adjustments (type of lighting, calculation parameters, views) are completely independent for the standard Raytracing calculation and the ReluxVivaldi calculation. Fig. 165 Calculation manager Since, in multiple separate calculations, there is always only one lighting group active, the demands on indirect calculations are higher than for an ordinary Raytracing calcu-

114 PART 2: ENHANCED FEATURES 114/140 lation, in which all the luminaires of a scene are switched on. Therefore, it might be necessary to set the parameters on higher values, especially for indirect calculations Artificial Light Control Group The control groups are automatically determined by Relux depending on how the luminaires are merged in the scene. Specifically, the following units are valid as control groups Each single or combination luminaire on the first level of the scene tree Each 'fixed' luminaire arrangement (line, field, circle) on the first level of the scene tree Each 'free' group on the first level of the scene tree (all containing luminaires, respectively) 1.) The luminaire heads of combination luminaires are treated equally. It is not possible to distribute individual luminaire heads separately over different control groups. 2.) If there are subgroups (e.g. fields or lines), then all the luminaires will be assembled in one control group. 3.) The free group can contain other objects apart from luminaires (cube, 3ds objects). Moreover, it can be divided into further subgroups. All luminaires are assembled in one control group. Yet, all luminaires in that group need to be of the same type. The switching status, which is adjusted in the properties dialog of the luminaire (control field 'luminaire On/Off') can be ignored in the ReluxVivaldi calculation as all the luminaires are switched on (as groups). The number of control groups that exists is displayed in the main dialog of the ReluxVivaldi calculation. Notes: In a separate control group calculation, there may be a large number of sudden calculations. It is therefore recommended that the luminaires be kept as separate as possible in the scene tree in order to keep track of them, rather than inserting more objects and luminaires (or arrangements) in subgroups. Prior to the calculation the luminaire arrangements will be checked. If errors are detected, an appropriate warning will be displayed.

115 PART 2: ENHANCED FEATURES 115/ Multiple Daylight Calculations If Daylight or Artificial and Daylight is selected as the type of lighting, the window daylight data will be active. One click on this will open a separate dialog (see Fig ), where the times for the multiple daylight calculations can be set. Fig. 166 and Fig. 167 Dialog for setting up multiple daylight times, on the left in automatic mode, on the right in manual mode with selected and modified entries. The daylight data dialog offers 2 modes to set up multiple daylight times as well as the types of sky. The initial selection of the date, time and sky model is performed in the same way as in the standard Relux Raytracing calculation. In automatic mode, the time set-up is interpreted as the initial value. In addition, time intervals and a number of repetitions can be selected. Clicking on Create list develops a respective set of time points with the desired intervals. Each newly created list removes old data (where this exists). In manual mode, each point in time and each sky type can be set individually and, by clicking on Add, can be attached to the already existing ones. A list can also comprise just a single time. The available points of time in the list can be selected and edited by double-clicking on them. Selected entries are denoted with * and current data appear in the date and sky-type button in the top section. Adjustments can be made there and, by clicking Overwrite, the selected entry can be modified and updated. The marker * will disappear after the modified entries have been closed.

116 PART 2: ENHANCED FEATURES 116/140 It can be interesting to combine the two modes. In the first step, a list of time points is created in automatic mode and then single data items can be modified in manual mode (e.g. change sky type). Note: At the moment it is only possible to choose hours and minutes as intervals, and the whole period must not exceed one day Calculation Results and Start of the ReluxVivaldi Module The result of a ReluxVivaldi calculation is a complete data record consisting of HDR images and additional information. It is bundled up and saved within the Relux project. It is tied to the relevant view that it was calculated for (similar to the images of the usual Raytracing calculation). If the ReluxVivaldi result needs to be defined for one view, it is possible to 'block' the view in the same way as for the normal Raytracing images. (cf. Chapter Fehler! Verweisquelle konnte nicht gefunden werden.) The information on existing ReluxVivaldi results appears in the blocked views where a small Raytracing image is displayed in the ReluxVivaldi preview dialog (this image is merely meant to provide information, it shows the number of individual control-group HDR images) Note: The ReluxVivaldi results are not listed in the output tree as yet. If at least one ReluxVivaldi calculation of a view of a scene is performed, the ReluxVivaldi module can be started by clicking on the ReluxVivaldi icon. The data of the calculated view is loaded automatically. (If there are several calculated views, the loading view needs to be chosen first). As the next step, dynamic simulations of the scene can be performed, control groups can be dimmed, and timelines set, etc. (cf. separate documentation for the use of ReluxVivaldi). Before closing the module, the adjustments done during the work with ReluxVivaldi can be saved in the ReluxVivaldi result associated with the view. Thus, in a later session, these will be available and can be worked on.

117 PART 2: ENHANCED FEATURES 117/ Planning according to EN :2011, :2007, or ASR 3/4:2011 Starting from ReluxSuite, version , the specifications as well as nominal values of the following directives were implemented in the work sequence: EN :2011, :2007, or ASR 3/4:2011 (Germany only). Similar to the road projects with their "evaluation classes", the user has now the simple option to assign a usage profile with defined nominal values to a scene. This option is available for indoor as well as outdoor systems Example project: Planning according to DIN EN :2011 Already after project creation via the "Interior" menu item (compare to fig. 175) the usage profile can be selected via the "Edit nominal values" icon in the slightly modified "Interior" menu window (next after the next menu window)(fig. 176). However, prior to that you can define the areas enclosing the space as follows: Room dimensions: L=6.0m x W=8.0m x H=2.80m. Rho: Floor=20%, Walls=50%, Ceiling=70% (default values). Fig. 168 Fig. 169

118 PART 2: ENHANCED FEATURES 118/140 In the "Edit nominal values" menu window (compare to fig. 177), you can now find the list of interior areas, areas of visual tasks or areas of activities according to chapter 5.2 of EN :2011. At the top of this menu window, the specifications of :2007 (chapter 5: Listing of lighting requirements) or of ASR 3/4:2011 (Lighting requirements for work spaces, work stations and activities) can be optionally selected in the "Manage profiles" menu item. For this example profile 5.26 "Offices: Writing, typing, reading, data processing" should be selected. Close the "Edit nominal values" window by clicking on "OK". When returning to the "Interior" menu window it can be seen that an evaluation pane was created in addition to the usage level. In addition to the usage level, this evaluation pane contains additional measurement areas for walls and the ceiling of a scene as required in EN :2011. If needed, these measurement areas can be deactivated in this menu window as well. Fig. 170 Usage profile according to EN :2011

119 PART 2: ENHANCED FEATURES 119/140 Fig. 171 Clicking on "OK" closes the "Interior" window and you can observe the scene in the 3D view of ReluxPro. As it can be clearly seen, the illustrated example contains already six suspended lights in the scene. These lights were places after product selection using the "Easy Lux" command. In the next step (compare to fig. 177, 178) you can place four desks as a group in such a way that they meet at one location. Notes: After right-clicking on the group, the "Centring" option can be selected from the context menu (compare to chapter 4). In the vertical "Objects" menu you can find an option called (visual) "Task area" under "Measurement elements". Using drag and drop, you can place this visual task in the proximity of the desks. After you set the snap grid: dx, dy and dz distance to 0.1 cm each, you can comfortably place the visual task such that it overlaps with the group of desks. Length and width are adjusted by sliding the "handles" or red dots, which become visible, if you mark the visual task. The area of the visual task in the central area of the measurement object is supplemented by the immediate surrounding area with a width of 0.5m. The usage level, which spans the entire room with a distance to the walls of 0.5 m, is now automatically the background area. By the way, this terminology is adapted from EN :2011 (compare to fig. 179, 180).

121 PART 2: ENHANCED FEATURES 121/140 Note: You can mark individual tables or objects simply by clicking on it with the mouse in order to select the "Define task area" option in the "Extras" menu. Now, a visual task with the immediate surroundings is created overlapping the table (compare to 181). Fig. 174 Fig. 175 Now, open the calculation manager, determine the maintenance factor (compare to fig. 182) and start the calculation. As soon as the calculation is finished, click on the Event overview icon (compare to 183, top right). Fig. 176 Result overview in ReluxPro

122 PART 2: ENHANCED FEATURES 122/ Calculation results As can be seen in fig. 184, the result overview has been significantly extended with ReluxPro. As already mentioned at the beginning of this chapter, the calculation results are shown, as well as the values requested and/or recommended by the standard to the right of the results in brackets. These values correspond to the profile from table 5.26 "Office: Writing, typing, reading, data processing, which you defined when creating the scene. The nominal values for this case are shown in the table in fig Usage Area Eav (horizontal) Eh,av [lx] Uo Ec (cylindrical) Ez,av [lx] Uo UGR Office Task area Surrounding Background Walls Ceiling Fig. 177 Note: The UGR classification of the lighting system is realized in the result overview according to the Table Method of the CIE Unified Glare Rating process, as the calculation according to the UGR formula, which is supported in ReluxPro, may not generate any loadable results (compare to DIN EN :2011). However, the Table Method has its limitations. The UGR value cannot be printed in all cases. If one of the following boundary conditions is not met, the UGR value is not shown on the result overview. 1. The scene must be rectangular or at least "almost rectangular". 2. One light type only may be used in the scene. 3. The scene must have a usage level (for the calculation of the scene dimensions, e.g. "4H 8H"). This can for example be the respective usage level within the evaluation area. 4. The lights must be at the same height above the usage level and must show maximum scattering of +/- 5cm (height difference). 5. Lights must be placed in the scene. Otherwise, no artificial light calculation is possible. 6. The lights must be suitable for an UGR evaluation. For example, combination lights with several light outlets do not meet this criterion.

123 PART 2: ENHANCED FEATURES 123/ ReluxEnergy ReluxEnergy is a powerful free-of-charge module for calculating the energy consumption of interior lighting in non-residential buildings. It is based on energy standards, such as EN and DIN , SIA380/4 & CTE HE-3. General information: ReluxPro data files can be imported into the ReluxEnergy program. Once the files have been imported, you then add the extra details regarding consumption and the information that is required by the standards. Changes which are made in ReluxPro data files will automatically be transferred to the ReluxEnergy project as long as you do not move or delete these reference data files. Note: An overview of the total energy consumption will be provided on the basis of the EN energy standard. No recommendations are given regarding the maximum overall energy consumption per year at the moment, since there are no recommendations contained in the standard. An overview is also available for the DIN energy standard, together with a "stop" light which provides direct feedback on whether the DIN standards have been attained or not. In addition to this, ReluxEnergy provides you with the total maximum permitted energy consumption per year, as well as the current energy consumption. The graphic user interface for ReluxEnergy Fig. 178: GUI of Relux Energy

124 PART 2: ENHANCED FEATURES 124/140 Note: To achieve meaningful results, it is necessary to have a basic knowledge of the energy standards, including EN and DIN , when using ReluxEnergy. Relux Informatik AG and their partners in Europe offer frequent training courses on this special field of light engineering. For further information please visit Use of the graphic user interface is highly intuitive. It contains two different tabs. 1. Energy evaluation (see above) is divided into three sections: Scene explorer, where all the rooms and sections are listed (green outline) Settings, where the data can be entered for the building and its zones (yellow outline) Results overview, for the building, individual rooms and sections (red outline) 2. Results: This tab works in the same way as the Print manager in ReluxPro and makes it possible to organize all the project results. The following two project examples illustrate the capability of ReluxEnergy.

125 PART 2: ENHANCED FEATURES 125/ Example 1: Project as per EN15193 Open a new ReluxEnergy project with a click on the icon, or press <Ctrl-N>. Insert one zone with a click on the icon, or press <Ctrl-L>. Import ReluxPro project files with a click on the icon, or press <Ctrl-I>. You can also import more than one project file and scene. An example is provided in your program installation folder at..\program\reluxsuite\examples\reluxenergy.rdf Select the rooms in the following menu, or just use the drag & drop function to import a room into your ReluxEnergy zone (this does not work with scenes that are extruded to the X-axis). Fig. 179 EN Select the EN standard; for every zone, you need to select a pre-defined profile from the combo box in the Additional settings tab for purposes of defining the annual hours of use (Fig. 186). The energy consumption will now be calculated automatically for each room and for the project overview. Rooms that include daylight openings will influence the calculation in a different way from rooms without daylight. Note: If you have to change the lighting design for any reason, select the room in the scene explorer and press F6. The room will now appear in ReluxPro and, after all the changes have been made, the results will automatically be transferred back into ReluxEnergy. General settings for room: (Fig. 187) You can fill in how many times you wish to evaluate this room, should one and the same room occur more than once in your building (this is typically the case in office buildings). Fig. 180 General settings

126 PART 2: ENHANCED FEATURES 126/140 Additional settings for room: (Fig 188): an average Absence factor of 0.2 is set as the default (This means 20%/day when the room is not in use). A light control system could significantly reduce the energy consumption. Click the Controlled constant illuminance switch box to enable or disable this option (it should only be enabled for use with daylight openings like windows). Fig. 181 General settings for section: select one of the presence control options to enable and define this option (Fig. 189). Fig. 182 General settings Fig. 183 Additional settings You have now completed your entries and will find the energy consumption for an individual room in the Results tab. Repeat the procedure (6 to 9) for each of the other rooms which have no daylight openings such as windows. General settings for room with daylight: (Fig. 190) You can fill in how many times you wish to evaluate this room, should one and the same room occur more than once in your building (this is typically the case in office buildings).

Modifications should be kept within limits. You should simply select the type of rooflight (Fig. 194). Fig. 188 Rooflight properties

129 PART 2: ENHANCED FEATURES 129/140 The project-related parameters for vertical windows, such as Window properties and Obstruction, will be not be provided by either ReluxEnergy or ReluxPro. If there is an atrium or a double-glazed facade, more parameters will need to be filled in. Please refer to DIN , where all these parameters are explained in detail. Fig. 189 Window properties Fig. 190 Obstruction Now you have completed your entries, you will find the energy consumption for an individual room in the Results tab. Repeat the procedure (6 to 9) for all other rooms with daylight openings such as windows. Note: there are several options for optimizing the power consumption of your project. Presence control Daylight dependent control systems Glare shield Dimensions and consistency of daylight openings (ReluxPro).

130 PART 2: ENHANCED FEATURES 130/ Example 2: project based on german DIN General information: the use of ReluxEnergy on the basis of DIN is fairly similar to the procedure for EN There are, however, two key points that differ in the EN and DIN standards: Only the DIN norm contains several utilization profiles. These profiles include fixed parameters that cannot be changed by the user. They form part of the standard. Fig. 191 Paragraph from the German DIN standard The consultant can evaluate the power consumption from the utilization profiles and a recommended maximum power consumption for each profile. The consultant can thus compare their planned power consumption with a reference value (for each individual zone and section). Fig. 192 excerpt from a German energy pass Open a new ReluxEnergy project with a click on the icon, or press <Ctrl-N>. Insert one zone with a click on the icon, or press <Ctrl-L>. Import ReluxPro project files with a click on the icon, or press <Ctrl-I>. You can also import more than one project file and scene.
