Analysis of heat load data of regional buildings in a university town in severe cold area

In order to save energy and reduce emissions in the field of public buildings, and the regional buildings in university towns account for a large part of energy consumption, this paper takes a university town in the planning stage in severe cold areas as an example to analyze the demand-side energy-saving potential. DeST software is used to simulate conventional energy-saving scenarios and regional planning scenarios. According to the energy-saving measures required in the code, considering the use characteristics of buildings with different functions, intermittent operation is carried out, so as to reduce demand-side heating demand, reduce energy consumption and minimize investment in energy systems. The simulation results show that the annual cumulative heat load of single buildings such as teaching building, experimental building, office building and canteen decreases by about 40%. Then, the load characteristic indexes such as standard deviation and load rate of buildings are analyzed, and it is concluded that different types of single buildings have different load fluctuation levels due to different use functions, and the load rate of regional buildings composed of single buildings is reduced. Therefore, when designing the energy supply system for university buildings, the above factors should be comprehensively considered, so as to optimize the investment and operation efficiency of the energy supply system throughout the year.
