with reflectance 80% ceiling, 50% wall, 20% floor, the C.U. shall not be less than .78.
To reduce glare the average brightness at 65° shall not exceed 1109 candelas per
square meter. To control veiling reflections, luminaire output in the 30°-90° zone shall
not be less than 64.1%.
Air Handling: (SKA only) side air passages for air supply or air return. Supply air is
discharged vertically. Optional side closure strips. Air return is also provided through the
