ASHRAE 90.1

Limits power density for a dining room from 1.0-2.2 W/ ft2, and for a conference, meeting, multipurpose room to 1.5 W/ ft2 so the power density greatly exceeds this because of the chandeliers

Exit signs meet criteria because they are LED and within the range of 2- 8 watts

Every separate system within these rooms is on a different dimmable control



Calculation Results:Community Rooms


The community rooms are used for anything from private parties to meetings. For a regular meeting, the theater-style setting can accommodate up to 200 people while it can hold 160 for a lunch or dinner meeting. I believe the following points are very important due the the nature of use of these rooms.

Very Important

- Reflected glare

- Uniformity of light distribution on the task plane

- Appearance of the space and the luminaires

- Color appearance

- System control and flexibility

- Facial Modeling

- Shadows

- Daylighting Integration and Control

- Flicker and strobe

- Recommended Horizontal Illuminance:100 fc

- Recommended Vertical Illuminance: 50 fc


Appearance is very important because this room is used for some very important occasions, but other issues such as reflected glare are important to notetakers when the room is used for meetings. The large community room can be divided into two smaller rooms by a moveable partition. The large-room ceiling is divided into four rectangular coves in which fixtures ‘G’ and ‘G2,’ staggered strips, are used. Two chandeliers (fixture ‘DD’) are placed within each rectangular section as well as three rows of two incandescent downlights each (fixture ‘R’). There are four wall sconces, fixture ‘FF,’ on the large west wall of the room, two on both the north and south walls of the room, and two on the east side of the room. All lighting systems in this room are on dimmable switches to accommodate for the room’s different uses. The chandeliers add elegance for formal occasions, while the incandescent downlights add warmth to the room. The wall sconces add a decorative touch between the tall windows, while the cove lighting reduces harsh facial shadowing.

Limits power density from 0.8-1.8 W/ ft2 which this lobby falls within

Lobby, library, lounge lighting controlled by timers

Lounge areas limit power density to 1.4 W/ ft2 which the lounge falls far below – this space is a bit dark though

I could not find guidelines for a billiards room, but the limit should naturally be a bit higher here – more research needs to be done in this area



The lobby area is the first thing that you see when you walk into the Westlake Recreation Center so appearance is very important. Theceiling is very high (about 35 feet) and there are many windows, so lighting in this area is more of a challenge. The lounge is a sitting area where people will wait or watch the large screen television that is present there. The library is also a sitting area, but a pool table sits in the center, so more light will be required here. I outlined the points below that I felt were very important for these spaces as required by IES criteria.

Very Important

- Reflected glare

- Uniformity of light distribution on the task plane (library)


- Color appearance


- Facial Modeling

- Daylighting Integration and Control (lobby)

- Flicker and strobe

- Source/task/eye geometry (library)

- Recommended Horizontal Illuminance: 30 fc


The lobby area consists of six evenly spaced fluorescent recessed downlights in front of the reception area where the ceiling is only 8’8” high. The ceiling height jumps to about 35 feet out in front of the reception desk. In the high ceiling are eight evenly spaced 10” metal halide downlights. This light source is used due to the high ceiling height – there are many windows, but these metal halide downlights are necessary in dark conditions. The lounge area is open to the lobby, but the ceiling is only 8’-8” high here and the light levels are drastically different. This area depends little on daylight and more on the wall sconces (fixture FF) on the north wall and ceiling sconces (fixture Q) spaced along the ceiling. There are tall windows surrounding the octogonal library so indirect lighting is used to create a soft atmosphere. A downlight (fixture Z) is placed directly above the pool table to provide enough task light for a game of pool.

Tandem wiring used for ballasts in all 2’x4’ troffersin the rooms surrounding and adjacent to the multipurpose room


Enough control devices are provided for the square footage

Although I could not find a specific category for this room, I guess it would fall into criteria for a normal multi-purpose room, which limits power density to 1.5 W/ft2 – the power density greatly exceeds this value


Calculations: Illuminance Values for Multi-purpose Room


The multipurpose room is designed as a place where dance classes can be held. There are ballet bars and full length mirrors on every other section of the octagonal walls and full length windows on the other sections. The points that I felt were important as outlined by the IES handbook are listed below.

Very Important

- Reflected glare


- Color appearance


- Daylighting Integration and Control

- Sparkle/desirable reflected highlights

- Points of interest

Somewhat Important

- Facial Modeling




For the multipurpose room, fixture ‘G,’ a staggered strip, was used within the cove to provide a softly lit indirect environment. The incandescent downlights (fixture ‘R’) add warmth to the room while providing more task light for when daylight conditions are low – they are controlled by a dimmable wall switch. The four metal halidedownlights (fixture ‘AA-1’) surrounding the translucent skylight are only used at night or when daylight conditions are low. They are necessary because of the 13 foot ceiling height. I think that incandescent downlights were overused in this space and I am not quite sure that this was the best route to take in terms of providing extra task lighting.

3450W/3710 ft2 = 0.93 W/ ft2

*This includes fixtures along the entire north exterior side of the building


ASHRAE 90.1

Limits a building entrance with a canopy or a freestanding canopy to 3 W/ft2 so 2.4 W/ft2 is well under the value

Limits building facades to .25 W/ft2 of illuminated façade area. The calculated value, 0.93 W/ft2 is above this value, but fixtures that are used to illuminate the walkway are also included in this number, so this is not very accurate


The exterior front facade consists of a drive around drop-off area that leads up to a covered porch area . The covered porch area then leads into the entrance of the building. The following was based on IES criteria for building exteriors with active pedestrian activity.

Very Important

- Color contrast/appearance


- Direct glare

- Light pollution/tresspass

- Peripheral detection

- Surface characteristics

- Source/task/eye geometry



Somewhat Important

- Light distribution on surfaces

- Sparkle/desirable reflected highlights


The lanterns on the two columns supporting the end of the front porch are very inviting give comforting glow to the exterior of the porch. The uplights on the inside of the porch make the skylight above appear to glow and it appears to almost be floating at night. Bollards light the walkway while floodlights accent the texture of the stone on the front of the building. Octagonal sconces add decoration to the exterior while adding a distinct pattern to the surface. I would have used more accent lighting along the front to graze and accent the texture of the rock sandstone.
