Making method and application of standards for energy consumption quota of civil buildings

Abstract

Based on the energy consumption survey in Wuhan, the paper provides the civil building energy consumption quotas according to the three energy efficiency indicators, which include the limit value, the admission value and the advanced value. The paper also presents the uses of different energy consumption quotas and analyses the difference between them. Adopting a statistical analysis method, the paper analyses the limit values of 39 kinds of building using SPSS software. Adopting a simulation method and a device isolation method, the paper provides 15 kinds of admission values and advanced values using DeST simulation software based on energy efficiency design standards. The paper also analyses that judging and excluding outliers are the basis for accurately formulating energy quotas. According to the building energy efficiency and fair principle, the paper gives unit building area energy consumption indicators for buildings with 39 kinds of different functions, air conditioning and heating energy consumption accounts for the proportion of building energy consumption, the limit values of energy consumption indicators of annual per capita energy consumption, per household, per bed, per student which are concerned with building function and standard deviations of the limit values.

Research on Formulating Energy Benchmarks for Various Types of Existing Residential Buildings from the Perspective of Typology: A Case Study of Chongqing, China

“…Meanwhile, different classification standards have been adopted in other studies. In a study on the energy quota of residential buildings in Wuhan, Hubei Province [102], residential buildings were classified into three types based on the proportion of local residential building unit area and the quality of residential communities: (1) buildings with a unit area less than 90 m 2 , (2) buildings of high-end residential types with a unit area of 90 m 2 and above, and (3) buildings of ordinary residential types with a unit area of 90 m 2 and above. Then a three-level energy efficiency evaluation index was designated, measured by the energy use per unit building area using the cumulative frequency method.…”
