Abstract
For typical residential buildings, no-large-scale and large-scale public buildings, according to China's Technical Guide for the Energy Efficiency Labeling of Civil Buildings, makes up missing data of the calculation benchmark and determines the boundary conditions for calculating the theoretical values of civil building energy efficiency. Based on equivalent full load hours method, develops a modular program and calculates building energy consumption for the demands of dynamic cooling and heating and lighting etc., finds out the corresponding relationship between star level's theoretical value of energy saving rate and specified-term limiting value in the Guide. With orthogonal experimental design and multiple linear regression, establishes the quantitative function of both the theoretical value of energy saving rate and main factors parameters, analyzes the impact of the control parameter on energy saving rate, and reveals the law of theoretical value of energy saving rate variation with the control parameter. For building energy efficiency labeling upgrade, presents technical measure need to be taken and analyses its feasibility. The results from the study can provide theoretical guidance for energy-saving design or retrofitting of civil buildings.
