Windows
Nationwide, heating and cooling energy attributable to windows account for about ten percent of energy consumption in buildings; when daylighting potential is considered, it can be even more. Efficient windows can lower heating and cooling energy while maintaining daylight and view.
Lower Heating and Cooling Costs
Windows are a major driver of building energy use. As they typically transfer heat much more easily than do insulated walls, window energy performance is of particular concern to heating and cooling energy use. Additional factors like solar heat, daylight and ventilation are important to consider for building energy performance.
Many window technologies can increase the insulating properties of windows. While most people realize that double-pane and triple-pane windows are more efficient than single-pane windows, other components can significantly improve window efficiency as well.

As demand for apartments and condos rises, builders and owners of multifamily buildings are prioritizing energy efficiency to make their properties especially attractive and affordable.
Commercial buildings consume 19% of primary energy in the United States, but energy-efficient technologies like the ones used by the National Renewable Energy Laboratory drastically reduce energy use in office spaces.
