The boss sends Coollites to southeast Asia. Coollite is one of Bristolite’s proprietary Green Building Technology products that are truly going global because they meet the International Energy Conservation Code (IECC). IECC requires a skylight to have a maximum Solar Heat Gain Coefficient (SHGC) of 0.40 and a maximum U Factor of 0.60. Coollite’s SHGC is 0.26 and U Factor is 0.45. Coollite’s outer glazing is coated with a proprietary spectrally selective material that blocks 85% of infra-red light and 99.2% of Ultraviolet light. The inner glazing of white prismatic directs 100% diffused, cool white light into the building’s interior.
