Abstract

The use of Low-Emissivity windows has increased over the past 20 years to account for over 80% of residential windows. These windows provide increased energy efficiency, but can results in vinyl siding deformation, or melting, on neighboring houses due to the focusing of sun energy from curved window surfaces. Our goal was to create a tool to predict the possibility of siding damage in a given house and neighboring house set up in any location in the United States. Important factors include prediction of sun angles and intensity, model of the sun intensity focusing from the window surface, application of a transient temperature analysis, and analysis of the damage over time. From the use of this tool, we identified the key factors that lead to the deformation of siding.
