Energy Film in Portland, OR, has developed a thin layer of film applied to glass and saves energy by using nanoparticle technology to reduce solar heat gain and to block UV radiation. Energy Film is a subsidiary of Artscape, Inc. which has been doing business world-wide since 1997.

School facilities are being challenged by local school boards nationwide to save energy and contribute to lessening the nation’s carbon footprint. While many steps have already been taken, more is required and windows are a major culprit in heat gain and loss.

The U.S. Department of Energy has stated that 60% of a rooms heat load in summer is due to solar heat coming into the windows. They have also stated that 25% of energy loss in winter is through windows. Energy Film is a unique and cost-effective solution to energy savings reducing solar heat gain in summer and retaining heat in winter.

Energy Film is applied to windows without the need for adhesives; and once it’s applied it is easily maintained.

• Its performance characteristics are achieved without the use of a mirrored surface. For historic buildings Energy Film doesn’t change the exterior features of the building.

• The application process is so easy that it only requires a squeegee, sharp utility knife for trimming, a straight edge, and a spray bottle with drops of liquid soap.
