Commercial Energy Savings Calculator


Estimate Your Energy Savings

Using the U.S. Department of Energy's DOE-2 energy simulation program, along with average energy costs for your area, the commercial energy savings calculator estimates your expected savings.

Use the drop-down menus below to select your location, glass type, and building and film type. The film type is based on the Solar Heat Gain Coefficient (SHGC), which is expressed as a number between 0-1. The best performing films have the lowest SHGC.

After you've made your selections, the energy savings calculator will show you how much you can expect to save - and how quickly you can expect a return on your investment.

If you do not see a city located near you in the drop down menu, please submit a request for a complimentary energy analysis for your area.

Small Commercial
*Small Office, School, Retail or Other with 20% Window-to-Wall Ratio
Based on a 5,000 square metre floorspace (55,000 square feet), 3 story building, with a window to wall ratio of 20% on all exposures. Film installed on all elevations. Energy savings determined using U.S. Department of Energy's DOE-2 energy simulation program. Actual savings are dependent upon many factors including actual local energy costs, glass type, film type, shading of glass from overhangs and adjacent buildings, etc. Consult with Solutia's Performance Films division for a detailed and more accurate assessment.
Large Commercial
*Office, Hotel or Other with 50% Window-to-Wall Ratio
Based on a 15,000 square metre floorspace (160,000 square feet), 5 story building, with a window to wall ratio of 50% on all exposures. Film installed on all elevations. Energy savings determined using U.S. Department of Energy's DOE-2 energy simulation program. Actual savings are dependent upon many factors including actual local energy costs, glass type, film type, shading of glass from overhangs and adjacent buildings, etc. Consult with Solutia's Performance Films division for a detailed and more accurate assessment.
High Performance Exterior Film
**SHGC 0.25 or lower
SHGC = Solar Heat Gain Coefficient. The lower a window's SHGC, the less solar heat it transmits. The SHGC (also know as the g-value in some countries) is the fraction of incident solar radiation that passes through a window, including solar energy that is directly transmitted and that which is absorbed and subsequently released inwardly by re-radiation and conduction. SHGC is expressed as a number between 0 and 1.
EnerLogic 35 Film
**SHGC 0.24, plus Low-e Glass Insulating Film
SHGC = Solar Heat Gain Coefficient. The lower a window's SHGC, the less solar heat it transmits. The SHGC (also know as the g-value in some countries) is the fraction of incident solar radiation that passes through a window, including solar energy that is directly transmitted and that which is absorbed and subsequently released inwardly by re-radiation and conduction. SHGC is expressed as a number between 0 and 1.

EnerLogic 35's low-emissivity (low-e) coating also improves window insulating properties, providing additional year-round savings.
High Performance Interior Film
**SHGC 0.25 or lower
SHGC = Solar Heat Gain Coefficient. The lower a window's SHGC, the less solar heat it transmits. The SHGC (also know as the g-value in some countries) is the fraction of incident solar radiation that passes through a window, including solar energy that is directly transmitted and that which is absorbed and subsequently released inwardly by re-radiation and conduction. SHGC is expressed as a number between 0 and 1.
Medium High Performance Interior Film
**SHGC 0.26 to 0.35
SHGC = Solar Heat Gain Coefficient. The lower a window's SHGC, the less solar heat it transmits. The SHGC (also know as the g-value in some countries) is the fraction of incident solar radiation that passes through a window, including solar energy that is directly transmitted and that which is absorbed and subsequently released inwardly by re-radiation and conduction. SHGC is expressed as a number between 0 and 1.
Medium Performance Interior Film
**SHGC 0.36 to 0.45
SHGC = Solar Heat Gain Coefficient. The lower a window's SHGC, the less solar heat it transmits. The SHGC (also know as the g-value in some countries) is the fraction of incident solar radiation that passes through a window, including solar energy that is directly transmitted and that which is absorbed and subsequently released inwardly by re-radiation and conduction. SHGC is expressed as a number between 0 and 1.
