Windows contribute to heat gain in buildings and can have significant impact on building’s energy use for cooling or heating. With jargon like DGU, VLT, SHGC, etc. selecting the right glazing from a wide variety of commercially available products is often a headache.
The ECBC provides guidance on specifying energy efficient window assemblies. This tool uses prescriptive criteria from ECBC to help you evaluate a fenestration product for your project. Simply provide information about the project and fenestration details into the form below. You may need to keep the glazing specification sheet handy. You may also save a report by clicking on ‘Generate’.
