In many buildings, temperature fluctuations (and subsequent energy bills) are due to sunlight streaming through office windows. Too much sun and things heat up. But when the sun shifts or goes down, so does the temperature.

The U.S. Department of Energy estimates that one-third of a building’s cooling load is from solar heat gain through windows, and nearly 75% of existing windows are not energy efficient.

One easy, and cost effective way to keep the temperatures in your building as constant as possible is with LLumar energy-saving window film.

Professional energy audits estimate that buildings retrofitted with LLumar energy-saving window films can realize annual energy savings as high as 15%, with reduced carbon emissions and a payback often as low as three years.

Energy-saving window film vs. window replacement

When you’re deciding between window replacement or installing energy-saving window film on existing windows in a commercial building, a number of factors may affect the choice you make.

Tenant complaints are often an early sign that your building’s windows need attention. New windows don’t always address complaints about heat or glare, and energy-saving window film can’t fix leaks or moisture, so identifying the real problem will help you focus in on the right window solution.

If the windows have air or moisture leakage, failed seals, or damaged frames (or if they aren’t structurally sound), then window film installation isn’t an option to address complaints or window problems. But if your building’s windows are structurally sound and in good condition, window film can often take care of several of the common problems associated with windows in commercial buildings.
