Discussion of the Energy-Saving Benefits of Heat Insulating Coating for Building Windows

Nano transparent heat insulating coating is applied to window glass in this study. The heat insulating coating absorbs thermal radiation, and reduces the thermal radiation transmittance of glass, thus, preventing the building heat load from increasing in summer, or reducing the consumption of heat energy in winter. Therefore, this study will design a scaled down building model room, where heat insulating coating is coated on the inner side of the window glass of the model room, and the thermal radiation isolation effect is tested. Finally, the building energy-saving benefit of outdoor heat insulation in summer and indoor heat preservation in winter is discussed.
