Dear users. Recently, I'm researching about effects of glazing properties in building energy performance. In esp-r, we can input various properties for glazing. All I have in my research, however, are just SHGC(Solar Heat Gain Coefficient) and U-value of the single layer of the glazing. I think I need more information for accurate input to esp-r.(for example, emissivity, transmission and so on) What properties do you think I need more for energy evaluation? You can also inform me how I can get needed properties from WINDOW5.2 (or other version) Ultimately, I need properties for the multi layer construction which is made up of single layers(only SHGC, U-value known). Thank you for your information in advance. Sincerely, Lewis Yook - Team Manager, Integrated Simulation Unit.
