Window Film Helps Earn LEED Points

Window film can help you earn up to 9 LEED® credits as part of your next retrofit or new construction project. EnerLogic 70 window film provides existing windows with more insulating power, lessens heating and cooling loads, and reduces the amount of artificial lighting needed in a space.


Commercial window film qualifies for points in the following LEED credit categories:


  • Improving Thermal Comfort (1 point). Window film can improve comfort by reducing hot and cold spots, and allowing HVAC systems to heat and cool more evenly. Because of reduced solar heat gain in the building, occupants will experience a considerable improvement in thermal comfort after window film is installed. Low-e window film also improves wintertime comfort by reducing heat loss.


  • Providing Daylighting and Views (1 to 2 points). Eliminating or greatly reducing the need for closed blinds or shades, window film improves the quality and amount of daylight into a commercial building. It also helps increase the connection between occupants and the outdoor environment by allowing blinds and shades to be left open.


  • Light Pollution Reduction (1 point). Our window film reduces light pollution by preventing light trespass from commercial buildings at night, which may qualify our window film for this LEED point.


  • Optimizing Energy Performance (1 to 3 points). EnerLogic improves the insulating performance of existing windows, reduces solar heat gain, and decreases HVAC run times and possibly the need for electric lighting, and based on U.S. Department of Energy software may provide up to 15% in energy savings.


  • Optimize Use of Alternative Materials (1 point). Using local and regional materials reduces air pollution and transportation costs associated with delivering materials to jobsites. Those customers having a project within 500 miles of our plant in Martinsville, Virginia may be eligible for a LEED credit for use of regional materials.


  • Innovations in Operations & Maintenance (1 point). Protection from harmful Ultraviolet (UV) rays helps keep assets from fading, and provides a layer of defense between occupants and skin-damaging UV radiation. If safety and security films are used to upgrade existing windows, they help protect occupants from injuries caused by broken glass.

Low-E Window Film Lifecycle Assessment

Harmony Environmental conducted on our behalf a lifecycle assessment of our window film, based on ISO evaluation standards 14040 and 14044, to evaluate cumulative cradle-to-grave environmental impacts.


Based on computer modeling of energy savings provided by our window film (using U.S. Department of Energy software), the assessment demonstrates that our low-e film products become carbon neutral less than two months after installation. With an average service life of 15-20 years, this commercial window film is expected to provide 14+ years of greenhouse gas (GHG) reductions after accounting for the product’s total carbon footprint.


The assessment found that upgrading existing windows with EnerLogic 35 window film produces less than 1 pound of carbon dioxide equivalent (CO2-e) per square foot of window film, which is 70 to 115 times less than the carbon footprint of replacing commercial windows.
