Life Cycle Cost Savings

Life Cycle Costing (LCC) aims to quantify the financial impact of a product over its entire life cycle to assist consumers in making decisions that will save them money over the long term.

According to the analysis by GSA's Proving Groundopens in new window, liquid applied solar-control films are cost effective for single-pane clear glass. They are not recommended for double-pane bronze glass in most climates.

Additional Guidance

28% of cooling energy demand is due to heat gain in windows. Applied solar-control films can reduce cooling demand by reflecting or absorbing solar energy before it reaches interior spaces. The reduce heat gain by absorbing or rflecting solar energy. Spectrally-selective films affect only the infrared spectrum, with little impact on the visible appearance of glass.

GSA's Green Proving Groundopens in new window recommends targeting buildings in climates with hot summers and mild winters, exposure to direct sun without exterior shading, and south, east or west orientations. Reflective film is currently more cost-effective and more broadly recommended. Consider absorbing films for historic buildings where reflected solar radiation might damage exterior wood trim.
