Benefitting from Solar Energy Due to Different Emissivity Levels of Multiple Glass Windows for Buildings

In the study, firstly, heat transfer coefficients of windows were calculated according to highest and lowest emissivity values. Secondly, monthly average solar radiation values determined. The coefficient for double, triple quadruple glass windows. Thirdly, in south, north east/west directions five climatic zones multiplied by shading factor, surface area energy factor discrete buildings. Thus, gain value heating period losses cooling was Finally, passive gains are during all climate zones. It has been that fifth zone south direction, loss from with 0.05 can be provided 167.9% double-glazed windows, 258.7% triple-glazed 349.1% quadruple-glazed
