WebEmissivity of a surface is a measure of its ability to radiate energy in comparison to a black body. For opaque bodies, the relation between reflectivity and emissivity is given by the … WebLow-emissivity glass (or low-E glass) provides natural light transmission while helping to limit heat gain and thermal energy transfer.. Due to continuous improvements in its thermal insulation and solar control performance, glass is a flexible building material that can help improve the energy efficiency of buildings.
