XO™ ARMOR feels ROI estimates are something we can provide along with clearly stated “base case” assumptions. Therefore, the ROI values stated below (in years) for several cities in the northern hemisphere is built upon the following:
- $0.10/kWhr
- Delta SHGC = 0.41
- $5/SQFT Installed Cost

Although XO™ ARMOR offers a broad spectrum of benefits, today the most common client request is to reduce energy costs and improve occupant comfort. Because of this, several tools have been developed to estimate return-on-investment (ROI) for prospective window film consumers.
In order to promote the independence of XO™ ARMOR’s ROI calculations, the following three tools are used depending on the application:
XO™ ROI |
The first tool by XO™ ARMOR takes advantage of weather data available from the National Renewable Energy Laboratories and uses easy-to-follow assumptions and calculations. |
RESFEN |
Along with XO™ ROI, when applicable we can supplement RESIDENTIAL calculations with software developed by Lawrence Berkeley Laboratories – RESFEN 5.0 (http://windows.lbl.gov/) |
COMFEN |
Along with XO™ ROI, when applicable we can supplement COMMERCIAL calculations with software developed by Lawrence Berkeley Laboratories – COMFEN 1.0 (http://windows.lbl.gov/) |
