摘要

The rapid development of rural economy has led the massive construction of rural dwellings, while the energy consumption is increasing correspondingly. A field study was carried out in local nine villages of Pearl River Delta, aims to look into actual conditions of rural residential buildings and explore the energy-saving potential, a detailed questionnaire survey was conducted as well to investigate the construction of rural dwellings and the influencing factors in design. The results of this investigation, which focused on dwellings built by residents, revealed that the built form of dwellings is generally Low-rise house, the average storey height ranges from 3.6 to 4 meters. The primary building envelope is 200 cm clay brick wall construction, and not insulated flat roofing, moreover, the high energy consumption of increasing multistorey dwellings has drawn attention.
