Abstract


This thesis aimed from“The Construction and Technology Committee”in Chongqing. The subject named“The integration of applicable energy-saving technology for rural residential”, transform the energy-saving rural residential through the passive strategies. On one hand, in order to improve the residence living comfort, we aimed on the residential space transformation, which could avoid or reduce the active energy consumption. On the other hand, improve the external materials and construction practices in order to improve their thermal performance and thereby reduce the energy consumption of rural housing, and give a comprehensive evaluation of the energy conservation of the envelop system in accordance with the economic development in rural areas in Chongqing. This thesis focuses on the latter, which is the analysis and research of the envelop system.Based on the field research in Chongqing’s rural areas, large amounts of basic data of rural housing’s external practice and residential types have been obtained and three types of rural housing have been chosen for research which are:(1) The traditional-interspersed layout. (2) The gallery type layout. (3) The centralized type layout, Then we put the centralized type and the gallery type layout as the research object. The energy-saving technology of envelop system countermeasures have been proposed combined with the region’s climate characteristic and the energy-saving technology status of the existing rural housing’s envelop.Based on the building energy simulation software Dest-h, and investigation of the rural housing and theoretical research, the rural housing’s energy consumption model of Chongqing have been established. By improving the thermal performance and construction practices, the energy consumption and energy-saving rate have been obtained. And then ,three types including economic、suitable and well have permutated 8 types of external structure according to the economic and technological conditions in rural areas of Chongqing and the energy-saving rate been compared through the energy consumption simulation. At the same time, the cost of the rural housing’s envelop has been entered and the cost of envelope systems have been obtained and compared. Finally, the technical and economic performance have been assessed and the optimal parameters for rural residential been figured out which provides scientific basis and references for the energy-saving design and reconstruction of the rural housing’s envelop.
