Research On Energy Audit And Energy Conservation Potential Of Public Building

Building energy consumption accounts for 1/3 of our country's total energy consumption,because of the special functional requirements and complex structure for large public buildings,it has high energy consumption and great potential of energy saving.This paper researches on the energy auditing method of large public buildings,combining building energy auditing with computer software technology,to obtain energy distribution rapidly and accurately and to discover the weakness of building energy use.At last it through the comprehensive consideration of various factors in the building achieve the greatest energy saving effect.First of all,this paper refers to the American ASHRAE standard,analysing the energy system and combine “Guidelines for Auditing Public Building Energy”,proposing an auditing methods for public building energy audits.Secondly,this paper research date statistics and analysis of energy audits to give the research information model and the energy consumption data statistical calculation method that can not directly measure.According to the research and calculation of the data,analyze the total flow model of building energy consumption and energy flow of every month.Then,determine energy consumption indicators and part of the index value by applying least squares method fitting.Audit a public building in Xi'an by applying this energy consumption data statistics and analysis methods and analyze the energy consumption of shopping malls.Based on the above analysis we find out the key energy-saving direction through weighting analysis and reach energy saving program combined with energy consumption simulation software to study the building's energy-saving potential.At last this paper design and achieve the building energy consumption computer audit software which based on the research of energy consumption data,energy auditing methods and energy-saving potential programs and refer to the enterprise software audit strategy.And it use B/S architecture,through the construction of functional requirements analysis and audit analysis model.This paper proposed an audit method suitable for public buildings,data statistical calculation method and Energy-saving potential analysis method which based on audit guidance.It design and achieve the building energy consumption computer audit software and provides a convenient and efficient way for building energy auditing and promote the development of building energy audits better.
