he design of the building envelope (including the glazing) impacts the energy demand of the building. Double-pane glazing is a better insulator than single-pane glazing. It is important to note that while more glazing (windows) increases daylight, the heat gain from allowing more light in may increase HVAC loads. Energy efficiency refers to less energy being used to accomplish the same amount of work, which is not the case here.
