Energy consumption quota of public buildings based on statistical analysis

The establishment of building energy consumption quota as a comprehensive indicator used to evaluate the actual energy consumption level is an important measure for promoting the development of building energy efficiency. This paper focused on the determination method of the quota, and firstly introduced the procedure of establishing energy consumption quota of public buildings including four important parts: collecting data, classifying and calculating EUIs, standardizing EUIs, determining the measure method of central tendency. The paper also illustrated the standardization process of EUI by actual calculation based on the samples of 10 commercial buildings and 19 hotel buildings. According to the analysis of the frequency distribution of standardized EUIs of sample buildings and combining the characteristics of each measure method of central tendency, comprehensive application of mode and percentage rank is selected to be the best method for determining the energy consumption quota of public buildings. Finally the paper gave some policy proposals on energy consumption quota to help achieve the goal of further energy conservation. ► We introduce the procedure of determining energy consumption quota (ECQ). ► We illustrate the standardization process of EUI by actual calculation of samples. ► Measures of central tendency are brought into determine the ECQ. ► Comprehensive application of mode and percentage rank is the best method for ECQ. ► Punitive or incentive measures for ECQ are proposed.
