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 = 1132.7 ft2
Floor Area of Reception = 573.9 ft2
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.

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.

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).

Lobby ASHRAE 90.1 Requirements:
Nyhavl Pendants: (118 W/fixture)*(10 fixtures) = 1180 Watts = 1.18 kW
Orbiter Wall Sconces: (54 W/2 fixtures)*(4 fixtures) = 108 Watts = 0.108 kW
CFL Downlights: (54 W/fixture)*(10 fixtures) = 540 Watts = 0.54 kW
2’x2’ Fluorescent Troffers: (64W/fixture)*(6 fixtures) = 384 Watts = 0.384 kW
Orbiter Micro Pendant: (50W/fixture)*(5 fixtures) = 250 Watts = 0.250 kW
Total Floor Area: 1706.7 ft2
Lobby Power Density: (1180W) + (108W) +(540W) + (384W) + (250W) = 2462 Watts/1420
ft2 = 1.7 W/ ft2
From ANSI/ASHRAE STANDARD 90.1-1999 - Table 9.3.1.2: The power density for a
lobby in an athletic facility is 1.8 W/ ft2, so 1.7 W/ ft2 is acceptable
