Analysis on the Energy-Saving Property of Solar Heat Reflective Coatings on Building in Beijing

Abstract:

To discuss the effect of energy saving of heat-reflective coating on building, the heat gain of exterior building envelope in summer and winter in Beijing has been calculated. The results indicated that the higher the reflectivity of coating, the better the energy saving effect. The energy consumption of roof and different direction walls were analyzed. The energy saving effect on roof is the best, however the effect is not obvious on the east and west walls. The heat reflective coating has no effect on north wall but exhibits effect on south wall. The energy saving effect of brick red heat-reflective coating is not obvious compared with the common brick red coating.
