Use window films

Window films help reduce air conditioning and heating energy use while allowing occupants to enjoy the view. In optimum situations, energy savings frequently pay back the cost of film installation in a year or less.

Use solar control glass.

In all but the most northern climates, the use of solar control glass provides significant energy savings. Solar heat gain is a serious problem particularly in buildings with large areas of south-facing glass. In warmer climates in buildings with more than 25 percent glass, consider using window tints or reflective coatings to reflect up to 90 percent of the solar heat striking windows.

Window U-Value

Use proper U-value in replacement windows.
When replacing windows, use windows with a 0.46 U-value or better that has optical properties appropriate for building use. (U-0.46 is a Low-E window in an improved metal frame.)

Window Treatments

Use interior window treatments.
In addition to being attractive, interior window treatments reduce energy consumption. Use insulating vertical or horizontal blinds and/or draperies to reduce heat loss and solar gain through window openings.

Window Insulation

Use insulation in aluminum frame windows.
Properly insulating your aluminum frame windows makes them almost as energy-efficient as wooden ones. Include an insulating section (thermal break) between the inner and outer aluminum sections of the frames.

Design and place windows based on internal wall characteristics.
The type of internal walls used in your facilities should influence the design and placement of windows. Highly reflective–but not glossy–light-colored walls spread daylight back from the sidewalls. Jewel-toned walls absorb more light and may require more supplemental lighting sources.
