Revisiting calculation methods of building energy consumption

Energy saving and low carbon have become the core characteristics of sustainable development in China’s building field, and the calculation of building energy consumption is becoming more and more important. After more than 10 years of rapid development, with the diversification and complexity of building shapes and types, the diversification of calculation methods, the update of energy-saving technology and the change of energy consumption calculation conditions and other factors, building energy consumption calculation and analysis methods will inevitably keep pace with the times. From the perspectives of materials, enclosure structure and building types, the changes of the simulated objects are explained, the static energy consumption calculation method is updated, and the change law is discussed from the perspective of the characteristics of the dynamic calculation method. An energy consumption prediction method based on the principle of data statistics has been added. From the perspectives of heat transfer mode and energy-saving technology, the new problems of energy consumption calculation faced by new energy-saving technologies are discussed, and finally the development direction of building energy consumption calculation methods is expected.
