Abstract:
We present a simple spreadsheet-based tool for estimating window-related energy

consumption in the United States. Using available data on the properties of the installed

US window stock, we estimate that windows are responsible for 2.15 quadrillion Btu

(Quads) of heating energy consumption and 1.48 Quads of cooling energy consumption

annually. We develop estimates of average U-factor and SHGC for current window

sales. We estimate that a complete replacement of the installed window stock with these

products would result in energy savings of approximately 1.2 quads. We demonstrate

that future window technologies offer energy savings potentials of up to 3.9 Quads.
