3 HAP Building Wizard Startup Guide This Startup Guide explains what the Carrier HAP Building Wizard does and how to use the software. We encourage you to read this Guide before using the Building Wizard. Contents 1.1 Program Overview Program Tutorial Program Operation PROGRAM OVERVIEW Welcome to the Building Wizard Welcome to Carrier s HAP Building Wizard program. The Building Wizard is a computer tool that provides an alternate method of entering space, schedule and construction data into HAP v4.2. HAP normally requires a bottom up approach for creating building data. Schedules plus wall, roof, and window assemblies are defined first. Then spaces are entered one by one. By contrast, the Building Wizard uses a top-down approach. The user describes the overall size and shape of the building, defines the type of zoning used and selects constructions and schedules from default lists. The Wizard then automatically generates data for all spaces in the building. By answering questions on two simple input screens you can create a building containing 100 spaces, or 500, or This vastly reduces the time and effort required to create building data. Therefore, the Building Wizard can increase your productivity when using HAP. It is particularly useful when performing preliminary design work and screening studies. If you have questions about the program: In the United States or Canada, please call or software.systems@carrier.utc.com. In other countries, please contact your local Carrier sales office or local Carrier distributor. Note that Building Wizard 1.0 is compatible with HAP v4.2. Building Wizard can only be installed and run on a computer which already has HAP v4.2 installed Using the Wizard to Create Buildings The Building Wizard makes preliminary design studies and screening studies in HAP easier. These are studies where only general details of the building are known, or where it is only necessary to account for general details about the building. In this context, the Building Wizard can ask a relatively small set of questions about the building, and by applying the answers broadly can quickly generate space, wall, roof, window and schedule data for the entire building. In its current form the Building Wizard is a separate tool from HAP. Therefore, to use this tool you: a. Run the Building Wizard to create building data and then insert the results into a HAP v4.2 project. b. Then run HAP v4.2 to use the building data for system design calculations or energy simulations. After starting the Building Wizard, the process used to create a building involves six steps: 1. Select a HAP v4.2 project. This is the destination for the building data you create in the Wizard.

4 2. Define building footprint data including the footprint shape and dimensions, the number of floors, percentage of glass and building usage type. 3. Define the ventilation requirements, internal loads, envelope construction and infiltration rates for the building. 4. Review the building you ve created in steps 2 and 3, and make changes if necessary. 5. Save the resulting spaces, schedules and wall, roof and window assemblies into a HAP project. 6. Exit the wizard or restart the process to create another building. Section 1.2 provides a simple tutorial showing how this process is put to use to create a building quickly. Section 1.3 provides more extensive explanations of each step, including images of the input screens. 1.2 PROGRAM TUTORIAL This tutorial explains how to use the Building Wizard to quickly create space, schedule, wall, roof, and window data for a building. 1. Start the Building Wizard Launch the Building Wizard software from the Windows desktop by pressing Start, and then choosing Programs, Carrier E-CAT / E20-II Programs, and Building Wizard Choose a HAP Project (if applicable) Note: The Building Wizard will create space, schedule, wall, roof and window data for HAP v4.2. The destination for this data is either an existing HAP v4.2 project or a new HAP v4.2 project. Therefore, the purpose of this step is to identify the destination for the data the Wizard will create. If one or more HAP v4.2 projects already exist, the Open Project dialog will appear. Choose the desired project or press the New button to create a new project. See for further details. If no HAP v4.2 projects exist, the Wizard will automatically create a new project. In this case the Open Project dialog will not appear You ll be asked to name the new project later in step 6. See for further details. 3. Define the Building Footprint On Wizard screen 1, define the size and shape of the building footprint, its orientation, number of floors and the building usage type. See for further details. When finished, press the Next button to continue. 4. Define the Building Details On Wizard screen 2, define ventilation, envelope construction, infiltration and internal load characteristics. See for further details. When finished, press the Next button to continue. 5. Review the Building Summary On Wizard screen 3, review the building floor plan, building area summary and space area summary data to verify it is correct. See for further details. If necessary press the Edit button to change individual space data, or press the Previous button to return to the previous screens to make changes. When data is correct, press the Finish button to continue. 6. Save Wizard Results in the HAP Project To save the data generated for your building, answer Yes to the Save data? prompt. Data will be saved into the HAP v4.2 project you selected in step 2, or a new project if that option was chosen. See for further details.

5 If you choose to save data and the destination is a new, untitled project, you ll be asked to name the project at this point. 7. Create Another Building or Exit from the Wizard If you wish to enter data for another building, answer Yes to the Create another building? prompt. This will return you to step 1. See for further details. If you wish to exit from the Wizard, answer No to the Create another building? question. 8. Use the Building Data in HAP Start HAP Open the project that was the destination for Wizard data (chosen in step 2 or named in step 6). Use the space, schedule, wall, roof, and window data generated by the Wizard for system design or energy analysis calculations. See for further details. 1.3 PROGRAM OPERATION Selecting a HAP Project After you start the Building Wizard and click the OK button on the title screen, the first task is to choose a HAP project. This project will be the destination for data you create with the Building Wizard. After you finish using the Building Wizard, you can run HAP, open this project and work with the data the Wizard created. Selecting a project works in two different ways, depending on the presence or absence of HAP v4.2 data on your computer Scenario 1 HAP v4.2 Project(s) Already Exist. When one or more HAP v4.2 projects already exist, the Open Project window appears, as shown in Figure 1.1. To open an existing project, highlight the project name and press the Open button. If you wish to create a new project, press the New button instead. When you create a new project, you ll be asked to name it later when your data is saved (see 1.3.5). Figure 1.1 Open Project Window Scenario 2 No HAP v4.2 Projects Exist. When no HAP v4.2 projects exist, the Building Wizard automatically creates a new project. Therefore the Open Project window does not appear. Instead the Wizard

6 will take you directly to the Building Footprint wizard screen (see 1.3.2). You will be asked to name this new project later when you save the data (see 1.3.5) Defining the Building Footprint After selecting a project, a series of three wizard input screens will appear. The first two screens collect input data describing layout, construction and usage of the building. The first of these is the Building Footprint input screen shown in Figure 1.2. The six sections on this screen are summarized below. Figure 1.2 Building Footprint Wizard Screen 1. General Information. The Building Type and Building Sub-Category inputs in this section will determine the defaults for ventilation, internal loads, constructions and infiltration that appear on the second wizard screen. Note that when you change either input, all items on the second wizard screen are automatically reset to default values. 2. Building Information contains a diagram of the building layout showing both the shape of the building footprint and how the floors of the building are zoned. The Building Shape input along with inputs from the Building Dimensions section (item 3 below) determine the actual size and shape of the building footprint. The Zoning Method input determines how the floors are zoned. The orientation of the building can be controlled using the compass icon located in the upper left-hand corner of the building view pane. By default, the compass North points toward the top of the pane. This indicates up is north.. To change the orientation, use your mouse to drag the compass pointer clockwise or counterclockwise to the desired point of the compass rosette. For example, if you drag the compass North needle clockwise until the West pointer faces up, the face of the building pointing up in the diagram is facing West. For example, Figure 1.2 shows a situation where up is Northeast.

7 3. Building Dimensions. Items in this section describe the dimensions of the building footprint. The input labels (X1, Y1, X2, etc...) refer to dimensions shown in the building view pane in the lower left part of the wizard screen. 4. Vertical Dimensions. The Floor-to-Floor input specifies the height of each floor and is used to calculate gross wall area. Number of Floors specifies the total number of floors in the building. The Floor-to-Ceiling item is used to determine the volume of spaces, which is necessary to determine infiltration airflow from air change data. If the Floor-to-Ceiling height differs from the Floor-to-Floor height, it indicates a ceiling air space. The Wizard will create a space for each zone of each floor of the building. For a multi-story building, each space on any intermediate floor (a floor other than the ground and top floors) will be identical to the corresponding space on all other intermediate floors. If you wish to create a set of spaces for only a single intermediate floor, then check the Typical Intermediate Floor Only checkbox. This feature is useful when all intermediate floors have the same thermal behavior and you intend to use multipliers to account for the actual number of spaces present. The feature allows you to reduce the total number of spaces created and this may simplify your work later in HAP. 5. Window. The % of Gross Exterior Wall input is used to determine the window area for each face of the building. For example if % of Gross Exterior Wall is 15%, then the window area for each face will be calculated as 15% of the gross exterior wall area. Note that this percentage is only used as an approximation. The Wizard will calculate the number of windows for each face using the dimensions of the Window Construction Type selected later on the Building Details wizard screen (see 1.3.3) that most closely matches the % of Gross Exterior Wall specified. Specified window dimensions may make it impossible to exactly match the window percentage specified, so the actual window area as a percentage of gross wall area may be slightly higher or lower than the percentage you specify here. 6. Building Identifier in the lower left corner of the screen is used to identify all spaces created by the wizard for this building. The label you enter here will be used as a prefix for the names of all spaces that are created. If your HAP project contains multiple buildings or design alternatives, this prefix will help you identify spaces belonging to same building For example, if you enter the label Alt1, then all spaces for this particular building will have the prefix Alt1 and will appear consecutively in the list of spaces that appears in the HAP main window. Once all data has been entered on this screen, press the Next button in the lower right to continue to the second wizard screen Defining Building Details The second wizard screen (see Figure 1.3) allows building details regarding ventilation airflow, internal loads, envelope constructions and infiltration to be defined. These inputs will apply to all spaces in the building. The screen is divided into six sections, which are summarized below. 1. OA Ventilation defines the outdoor ventilation airflow requirements for spaces in the building. Two requirements can be entered. This helps with applications that have dual requirements, such as airflow per person (CFM/person) and airflow per unit floor area (CFM/sqft). If only one airflow requirement exists, define the second requirement as zero. 2. Occupancy defines the density, hourly schedule and activity level for occupants in the spaces. The drop down list for the schedule contains a series of typical schedules and any schedules contained in the HAP v4.2 project you selected earlier (see 1.3.1). If you select one of the typical schedules, the Wizard will add it to the project along with the spaces it creates. 3. Overhead Lighting defines the fixture type, density and hourly schedule for overhead lights. As with occupants, the drop-down list for schedule contains typical schedules and any schedules in your HAP v4.2 project. If necessary, the Wizard will add the schedule you choose to your project along with the spaces created.

8 4. Construction Types defines the construction assemblies used for exterior wall, roof and window elements of the building. Each drop-down list contains typical assemblies as well as any wall, roof or window assemblies defined in HAP v4.2 project you selected earlier (see 1.3.1). If you select a typical construction, the Wizard will add it to the project along with the spaces it creates. 5. Electrical Equipment defines the power density and hourly schedule for electric equipment in the spaces. This includes electric equipment such as computers, copiers, laboratory equipment or kitchen equipment. As with occupants and lighting, typical schedules and schedules from your project are contained in the drop-down list. When necessary, the schedule you choose will be added to the project along with the spaces created. 6. Infiltration defines the infiltration air changes per hour for spaces in the building. Infiltration will only apply to spaces having a perimeter exposure. The same infiltration value will be used for cooling design, heating design and energy simulation conditions. Once all data has been entered on this screen, press the Next button in the lower right to continue to the third wizard screen Reviewing the Building Summary Figure 1.3 Building Details Wizard Screen The third wizard screen (see Figure 1.4) summarizes the building you defined on the first two wizard screens. This provides a chance to review the data before saving the data in your HAP project. The Building Summary screen is divided into three sections which are summarized below. 1. Floor Plan provides the floor plan diagram from the Building Footprint screen. It shows the size, shape and zoning for the building, and indicates the orientation of the top face of the building.

9 2. Output Summary Data provides overall statistics for the building including number of spaces and totals for floor area, area by floor, gross wall area and window area. Sometimes inspection of these statistics will point out a problem with inputs. 3. Space Data provides a summary of data for each space in the building. For each space the floor area, gross wall area, window area and roof area are shown. The data in this table cannot be edited. However, if you press the Edit button to the right of the table, a window will appear containing a spreadsheet showing ventilation, internal load, construction and infiltration data for each space. Data in this spreadsheet can be modified. This feature is useful for those buildings with non-uniform usage or construction, as it allows internal loads, ventilation and construction assemblies to be changed on a space-by-space basis. The spreadsheet in the Edit window also allows the space name to be revised. The Wizard automatically names the spaces according to the building identifier, the floor number and the zone number. For example Alt1-F001-Z04 is the space for building Alt1, floor 1, zone 4. In some cases users wish to supply more meaningful names for the spaces. This can be done via the Edit spreadsheet. Finally, wall, roof and window areas cannot be modified via the Edit spreadsheet. Areas can only be changed by returning to the Building Footprint wizard screen (see 1.3.2) and modifying inputs on that screen. If you need to return to an earlier wizard screen to correct problems press the Previous button. If all data is OK, press the Finish button to proceed Saving Building Data to the Project Figure 1.4 Building Summary Wizard Screen After leaving the Building Summary screen you are asked whether to save the data for the building you just created (Figure 1.5). Saving the data places it in the HAP v4.2 project you selected at the start of this process (see 1.3.1). Once saved, you can run HAP and use the building data for system design and energy simulation calculations. Press Yes to save the data. Or, press No to discard building data.

10 Note: If the destination for wizard data is a new, untitled project, you will be asked to name the HAP project when data is saved. This happens when you asked to create a new project at the start of the process, or no HAP v4.2 projects existed initially and a new project was created automatically Creating Another Building Figure 1.5 Save Data? Window Finally, the Wizard asks if you would like to create another building (Figure 1.6). Pressing the Yes button will take you back to the start of the process (see 1.3.1) to select a HAP v4.2 project. Pressing No will cause you to exit from the Wizard. In some situations, you may want to create multiple buildings representing different design alternatives and therefore will need to make multiple passes through the wizard to create these alternatives. In this situation, select Yes to make another pass through the building creation process. In other situations you may only need to create one building design. In this case, press No to exit the Wizard. After exiting the Wizard, you can run HAP to use your data. Figure 1.6 Create Another Building? Window Using Wizard Results in HAP After you exit the Building Wizard, you can run HAP v4.2 to use the building data you created: 1. Start HAP v Open the project you specified when using the Building Wizard. This is either the project selected at the start of the wizard process (1.3.1), or the new project you named when you saved it (1.3.5). 3. On the HAP main window, the spaces you created with the Building Wizard will appear. Also, any schedules, or wall, roof or window assemblies used in the building will appear. 4. Building input data can be revised, if necessary. The data can also be used in system design calculations and energy simulation.
