ROOM 1-Classroom:
 VDT Horizontal avg. @ work plane of 2.5’ = 260 lux  IES Recommendation = 150 lux
 E horizontal avg. @ podium with work plane of 4.5’ = 289 lux  IES Recommendation = 150 lux
X
E vertical avg. @ projection screen with all lights on = 142 lux  IES Recommendation ≤ 50 lux
(See calculation planes below)
Calculation plane @ Projector Screen (with all lights on):
The design criteria cannot be met (for the projection screen) by allowing all lights to be in one zone,
rather the front row of lights (closest to the projector) should be on a separate zone (zone 2) to allow for
the front row of lights to be turned off when the projector is in use. Zone 1 contains the other four rows
of linear luminaires.
After placing the first row of luminaires on their own zone (Zone 2) and shutting them off:
 E vertical avg. @ projection screen Zone 2 turned off = 41 lux  IES Recommendation ≤ 50 lux
ROOM 2-Student Lounge/TA Workspace:
 VDT Horizontal avg. @ work plane of 2.5’ = 602 lux  IES Recommendation = 150 lux
 Residential Living Room Vertical avg. @ 4’ = 275 lux  IES Recommendation = 30 lux
(See calculation planes below)
Calculation plane @ 4’ Vertical:
 Residential Living Room Horizontal avg. @ floor = 329 lux  IES Recommendation = 30 lux
