Study on Energy Audit and Energy Consumption Calculation Model of Public Office Buildings in Xiangtan City
With the rapid growth of building energy consumption in China,building energy audit has ushered in a new round of development and opportunities.In this paper,a split calculation method of public building energy audit based on Guidelines for Energy Audit of State Office Buildings and Large Public Buildings is proposed.Taking Xiangtan Museum,Planning Museum and Party History Museum as examples,the energy consumption of lighting system,service equipment system,air conditioning and ancillary equipment system is split and calculated through the basic building information obtained through investigation,and all energy consumption coefficients are revised.The calculated energy consumption of the whole building from 2020 to 2022 is 328.8 tce,348.5 tce and 374.9 tce respectively,and the actual energy consumption obtained through investigation is 329.1 tce,355.0 tce and 396.9 tce respectively,and the monthly relative error of both is less than 15％.This method provides a new idea for the calculation of energy consumption of public buildings and a theoretical basis for the further transformation of building energy efficiency.
