Description

Purpose / Context - Residential energy consumption except heating (RECEH) plays an important role in China. The purposes of this study were to analyze RECEH in Beijing and find out the influence factors of RECEH. Methodology / Approach - A survey of 2024 households in Beijing was undertaken. The investigat-ed residences were located in 23 residential communities and two farmers markets. Questionnaire contents included six aspects: building information, building envelope, living style, auxiliary household appliance, electricity consumption and other energy consumption. While electricity consumption in 8571 families, gas consumption in 189 families, and water consumption in 414 families have been measured by the meter readings last for four months and a year. This paper obtained the results by a method combining data statistics with grey correlation analysis. Results –The results showed that the annual average consumption of electricity and air conditioner electricity in each household was 1689 and 160.4 kWh separately. In addition, the quantity of annual average gas usage was 140 m³/household and the water consumption was 80 m³/household. The analysis of influence factor showed that usable floor area and number of household members was the most profound impact on the entire electricity and gas consumption respectively. The most im-portant influence factor of high, middle, low level electricity consumption families was the number of glass layers, number of household members and temperature setting of air conditioner separately. While construction year, number of household members and construction year became the most important influence factor of high, middle, low level gas consumption families separately. Key Findings / Implications – · Residential energy consumption except heating in Beijing has been investigated. · Influence factor was analyzed by grey correlation analysis. · The effect of usable floor area and number of household members was the strongest contribu-tion to the entire electricity and gas consumption respectively. Originality - This paper analyzed residential energy consumption except heating in Beijing and ob-tained the influence factor by a method combining data statistics with grey correlation analysis.
