Abstract

In order to grasp to the energy consumption present condition for residential buildings, a questionnaire survey had been carried out in Changsha city Hunan Province and Luoyang city Henan Province. This paper has been present the preliminary investigation results. The results can be summarized as follows; 1) The households with floor area ranging 75 m-125 m account for more than 52% of the total amount investigated. More than 64% buildings had been constructed in recent ten years. 2) Total energy consumption for every household with 71, 856 MJ/Year in Luoyang is 3.1 times of that in Changsha being 23, 431 MJ/Year. But annual electricity energy consumption in Changsha is 2.2 times of that in Luoyang. 3) The space heating thermal demand accounts for more than 70% of the total energy demand in heating district. 4) There is much adoption of the saving energy countermeasure in two cities. But there is still considerable energy saving potentials in residential buildings.
