Assuming we have both lamps on in all the fixtures then the density would be as follows: 12 total fixtures x 59 watts per 2 lamp ballast = 708 watts 708 watts 708 watts / 847 sf = 0.835 watts per sf. 0.835 watts per sf. This is well within the allotted 1.4 w/sf 1.4 w/sf allowed by ASHRAE standards.

Worst case scenario December at 9am. Worst case scenario Assumed to be a clean room December at 9am. Worst case scenario AVG: 30 fc 12 month cleaning cycle Vertical illuminance RCR: 1.97 Workplane Illuminance: AVG 40 fc LDD = .86 LLD = 2800/2950 = .95 RSDD = .88 BF = .88 Total LLF = .86 x .95 x .88 x .88 = 0.63 0.63 Power Density: Power Density The goal of using the skylights was to decrease the power density of the space. 35 fixtures with 2 lamps apiece, utilizing a two lamp ballast at max 64W (assume no dimming) 35 x 64 = 2240 watts 2240/3132 sf = 0. 0.72 watt 72 watts/sf. This is well within range of the 1.25 w/sf 1.25 w/sf maximum required by ASHRAE standards.
