Statistical Analyses on Summer Energy Consumption Characteristics of Residential Buildings in Some Cities of China

摘要

The purposes of this paper are to analyze energy consumption characteristics and to find out influence factors of residential energy consumption in some cities in China.The investigated residences were located in seven cities of five architecture thermotechnical design districts.Questionnaire surveys taken in summer revealed building characteristics,the possession and utilization of domestic energy use equipment,household characteristics and thermal environment.Summer residential energy consumption characteristics in these cities are analyzed contrastively.Quantification Theory Ⅰ is used to analyze the qualitative and quantitative influence factors of energy consumption in each city.It is found that the household total energy use amount in Hongkong is largest,and the values in Beijing,Shanghai and Changsha are smaller but also at a high level,while the residences in Kunming,Harbin and Urumqi consume the least energy.The main influence factors on summer energy consumption of all the cities include the location,the number of family member,annual income,and daily use hours of air conditioners.
