ABSTRACT
Modern factory-built windows and window components are available that can greatly reduce portions of building energy consumption attributable to windows, skylights, clerestories, and other fenestration apertures. The adverse energy consequences of using larger fenestration apertures for good daylighting (thereby realizing its attributes) can be reduced or even eliminated through good fenestration design and construction, coupled with adaptive aperture control. The result can be buildings with greater comfort, more productive occupants, and substantially reduced purchased energy costs. As we pass the peak of world oil production, approach peaks in other fossil-fuel supplies, and seek to reduce global warming through reduced fossil-fuel use, considerable energy and dollar savings are possible through the use of the new high-performance windows and window attachment products.
