Simulation of Summer Energy Consumption of a Low-Energy Building in Severe Cold Regions and Comparative Analysis of Measured Data

Energy consumption simulation calculation for ultra-low-energy buildings and comparative analysis with actual operational data. It can provide reference for the rationality of ultra-low-energy building energy simulation application and the feasibility of operation management and simulation optimization operation strategy. Take the Sino-German Energy Conservation Demonstration Center of Shenyang Jianzhu University as an example. Simulation of building load is done by using building energy simulation software DeST-c. Select a few days with little difference in outdoor temperature for comparison and compare the simulation results with the measured energy consumption results. DeST-c’s simulated cumulative cooling load is 998.26, 1099.54, and 838.13 kWh. The measured load is 1233.94, 1220.35, and 1020.46 kWh and is combined with the actual analysis of the reasons for the difference. Through the comparison between simulated and actual measurement, the actual load is larger than the simulated load. The maximum deviation between the simulated load and the measured load is about 19%, indicating that the construction process is poor during the construction phase, making the actual load larger. At the same time, it also provides reference for the rationality of DeST-c software for the simulation application of low-energy building energy consumption in severe cold regions.
