Abstract

Population growth and high rise of living standard increased energy demand in the construction sector considerably. In buildings, a lot of energy is lost through windows glasses. The purpose of this study is to investigate the effect of double-glazed glass with nano-aeorgel (nanogel) insulation compared to simple glass of 3mm and double-glazed glass on solar gain reduction of cooling load of an office building in Bushehr with hot and humid, Shiraz with warm and dry and Tabriz with cold climate. For this purpose, a three-floor office building is simulated as a model building by Designbuilder Software and solar heat gain and cooling load are calculated for each case. The results indicate that the use of glass nanogel in Bushehr reduced 62% of solar gain and 21% of cooling load compared to the simple glass window. Using nanogel glass in Shiraz reduced 70.3 % solar gain compared to simple glass, 25 % of cooling load compared to simple glass and 8 % compared to double-glazed glass. Using nanogel glass in Tabriz has caused to decrease solar gain about 60% and cooling load 16.6% compared with simple glass.
