Windows have long been used in buildings for daylighting and ventilation. Many studies have even shown that health, comfort, and productivity are improved due to access to natural light. High-performance, energy- efficient window and glazing systems can dramatically cut energy consumption due to heat gain and loss. These high-performance windows feature double or triple glazing, specialized transparent coatings, insulating gas sandwiched between panes, and improved frames. All of these features reduce heat transfer.
Although reducing the amount of glazing may be possible, it also may not be. Regularly occupied spaces should have glazing and with an adequate ratio of window to floor area.
In most regions, the south elevation will receive the highest amount of solar gain. Darker colors will act as a heat sink and absorb solar energy.
