Calculation and analysis of energy consumption for energy efficiency of residential building in severe cold area

摘要

With the new energy simulating software - Energy plus to calculate energy consumption for energy efficiency of residential building in severe cold area. This paper Presents impact factor such as building envelope construction, temperature schedule and internal heat gain on energy consumption for energy efficiency of residential building. The calculated result is tested by long -term field measurements. Provides reference to compute energy consumption and heating load prediction for energy efficiency of residential building in engineering.Finally, it is concluded that improving building envelope construction much is not very necessary to save energy.
