An insulated glass unit (IGU) combines multiple glass panes into a single window system. The panes of glass in IGUs are separated by a spacer and a still layer of air or gas. Double glazed glass is an ideal energy efficient choice with the added benefit of minimizing noise.

Double-skin facade, or DSF, is an envelope construction composed of two transparent layers that are separated by an air spacing. the DSF is a form of active facade, because it uses equipment, like fans or solar/thermal sensors.

Low-E coatings have been developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted. Radiant energy is one of the important ways of heat transfer occurs with windows. Reducing the emissivity of one or more of the window glass surfaces improves a window’s insulating properties.
