Abstract

Abstract: A store as one kind of large public building energy consumption was tested and analyzed through gray box model in this paper. Unclear energy systems and equipments are investigated and the opration time is estimated. The construction item energy consumption composition is obtained. The results show that lighting energy consumption accounted for the total energy consumption of 29.71% in the market building. Since the building is located in the severe cold zone, heating energy consumption is still main part of total energy consumption up to 16.42%. Air conditioning energy consumption is only 13.88% because of the short summer. Energy consumption in special region such as restaurant and cinema reached 22.24%, and the elevator energy consumption is 7.13%. The results show that the inside building energy consumption composition can be obtained effectively through gray box model which has great significance on evaluating building energy consumption.
