A Study Of Standard Methodologieson Building Energy Simulation

Building energy simulation is a technology of calculating and predicting building energy consumption by computer.At present,building energy simulation has been widely used in building energy saving and green building industry,and has become an important technical means to judge the level of building energy saving.At the same time,building energy simulation is more complex,involving a series of processes such as geometric modeling,building parameters input,etc.As for the standardization method of building energy consumption simulation,only "Standard for green performance calculation of civil buildings" has been mentioned in our country.The purpose of this paper is to fully absorb the standardization method of building energy simulation abroad and optimize the existing standardization method in our country on the basis of understanding the current situation of domestic building energy simulation industry.This paper mainly includes the following research contents and results.Firstly,through the investigation of actual building energy consumption simulation cases and the questionnaire survey of building energy consumption simulators,we can fully understand the current situation of domestic building energy consumption simulation industry.Secondly,the standardization methods of building energy consumption simulation in the United States,the United Kingdom,Canada and China are compared in detail,so as to sort out the non-standardized operation in the domestic building energy consumption simulation industry and summarize the advantages and disadvantages of the standardization methods of building energy consumption simulation at home and abroad.Finally,some technical points of building energy consumption simulation are studied in detail and standardized simulation suggestions are given.Then the existing standardization methods of building energy consumption simulation in China are improved.Finally,the proposed standardization method of building energy consumption simulation is verified by a case study.In this paper,the existing standardization methods of building energy consumption in China are optimized to avoid the influence of non-standardized operation on the accuracy and consistency of simulation results in building energy consumption simulation.
