Our energy-saving window film can boost the performance of nearly any glazing system, significantly reducing energy consumption and peak demand and lowering carbon emissions. Professional energy audits estimate that buildings retrofitted with our energy saving window film could realize annual energy savings as high as 15%. Return on investment can be achieved in as little as three years. Is Your Building Energy Efficient? 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. LLumar offers an Energy Audit process that utilizes widely accepted U.S. Department of Energy analytics to analyze how our energy saving window films can improve efficiency to deliver significant savings and rapid payback.
