Lighting Depth Part 2: Lobby/Reception Space

Transcription

1 Lighting Depth Part 2: Lobby/Reception Space Metaphor and Ideas: My next space of redesign is the lobby/reception area. Metaphorically, the lobby is like the table of contents of a book it gives you information on where you want to go and is the precursor to the rest of the Recreation Center. I wanted to draw attention to the reception desk, since it is the first area that one would go to upon entering the Rec Center (to sign in). Since the lobby has a very high ceiling and is very open, I next wanted to make the area more inviting. I also wanted to distinguish the snack area from the rest of the lobby. Floor Area of Lobby = ft 2 Floor Area of Reception = ft 2 Lobby Height: 27 Reception Height: 8-8 Design Criteria: Important: The appearance of the space is important because it is a high pedestrian traffic area and also the first area that one would see when walking into the building. Color appearance ties into the whole appearance issue and is important because there are so many differently colored surfaces in the room. Points of interest are also important since the reception desk is the most important area in the room and I would like for that to be the first thing that people notice when entering the building. Shadows are also an issue because the room is so large. Somewhat Important: Surface characteristics are of some concern because there is a tile floor, a wood ceiling, egg-shell colored flat walls and then a brick wall. Sparkle/desired highlights are another issue since I would like there to be an element of sparkle to the reception desk. Surface Characteristics: Reflective Wood Ceiling: ρ 35% Brick: ρ 30% Alkyd Eggshell Walls: ρ 50% Tile Floor: ρ 17% The walls and brick were straightforward, but I had to estimate the reflectances of the ceiling and floor because there was nothing in the drawing specs and I could not find them online

3 Design Ideas: For the lobby, I used metal halide pendants to bring down the ceiling and add something to the open space. I used arm-mounted wall sconces over the snack area to separate this area from the rest of the room a bit and make it seem cozier. To draw people into the reception area and add sparkle, I used small halogen pendants along the exterior and around the curve of the desk. Compact fluorescent downlights were used in front of the reception desk where the ceiling drops from 27 to 8-8 for general lighting and 2 x2 fluorescent troffers were used to light the two desks in the reception area.

4 Fixture Location: Location: The metal halide pendants are located 10 feet from each other horizontally and 8-8 from each other vertically. The wall-mounted Orbiter sconces are located 9-3 from each other on the South wall and 19-6 from each other on the North-most columns. The small pendants lining the reception desk are located 4-0 apart from one another and the CFL downlights are located 4-9 from each other horizontally and 6-0 from one another vertically. The troffers and CFL downlights lining the back wall are in a 2 x2 grid

6 Circuitry and Controls: Figure 1.5 Fixture Circuiting Diagram Circuiting: Five of the Nyhavl Pendants shall be operated from a timeclock based on the following hours: Monday Friday (Sept. May): 6:00 am 10:00 pm Monday Friday (June August): 6:00 am 9:00 pm Saturday: 11:00am 5:00 pm Sunday (Dec. April): 11:00 am 5:00 pm Sunday (May Nov.): 12:00 pm 5:00 pm The other five Nyhavl Pendants are operated from a photocell mounted on the ceiling. When incoming daylight falls below 30 footcandles at the designated point, the remaining five Nyhavl Pendants will switch on. The remaining fixtures in the room are controlled from occupancy sensors (denoted by the single gang switches on the diagram).
