| With the rapid advancement of urbanization,a large number of aging residential buildings built in the 1980 s and 1990 s in my country are seriously lagging behind the demands of the times.According to statistics,the number of aging houses in Northwestern China is large,accounting for about 42% of the stock of houses.They are located in the severely cold and cold area of my country’s building thermal design zone.The temperature is low in winter and lasts for a long time.Family members are more susceptible to harsh conditions.The impact of poor weather conditions,dilapidated building conditions and outdated heating equipment has resulted in higher energy consumption behavior,resulting in the dual problems of "high energy consumption" and "low energy efficiency",and also hindering the economic and social development of the Northwest and the aging residents’ yearning for a high-quality life.In recent years,although the Northwest residential energy-saving standards have been continuously improved,the electricity consumption of aging residential buildings has shown a rapid upward trend,facing the risk of compensatory growth,which has highlighted the necessity of exploring the law of energy consumption and promoting its low-carbon development.This study takes the electricity consumption of aging residential households in cities in Northwest China as the main research object.It establishes an index system from five dimensions of climate,architecture,households,equipment characteristics,and energy consumption behavior.It adopts a stepwise regression model and a path analysis model,based on Northwest my country.Survey data of 1462 households in 46 aging communities in three cities in the area of Category II climate zone and Category VI climate zone,quantitatively determine the effect of different factors on the electricity consumption of urban aging residential households and the path of action,and propose targeted Countermeasures and suggestions for energy saving and consumption reduction of old houses.The results of this research are as follows:(1)The key factors influencing the electricity consumption of aging residential households in cities in the Ⅱ climate zone are household size,the number of other commonly used household appliances,heating equipment usage habits,property rights,air-conditioning behavior,number of air-conditioners,annual household income,winter window opening time,Heating method.(2)The key factors influencing the electricity consumption of aging residential households in cities in Category VI climate zones are household size,main household cooking methods,heating equipment usage habits,property rights,annual household income,number of other commonly used household appliances,window opening time in winter,and average Cooking times per day,number of rooms,living floor.(3)From the perspective of the total effect of the factors,the family size has the most significant impact on the electricity consumption of the aging urban residential households in the two types of climate zones,followed by the annual household income.From the perspective of the direct effects of the factors,the family size,family annual income,heating equipment usage habits and the number of commonly used household appliances have the most significant positive impact on the electricity consumption of urban aging residential households,and the negative impact of the form of property rights is the most significant;affected by climatic characteristics And the impact of resource endowments,the significant difference between the two types of climatic zones lies in household cooking methods and summer cooling methods;aging equipment and aging appliances have a significant effect on household electricity consumption.From the perspective of the indirect effects of factors,the annual household income has the largest indirect effect on the electricity consumption of aging residential households in cities in the two types of climate zones. |
