Research on Rural Building Thermal Environment and Energy-efficient Design in Guanzhong

With economic development , the farmers' living standards improve , people come to realize the importance of comfortable and healthy indoor thermal environment to live and work , but due to the impact of traditional living patterns and constructed in such a manner , the country house still exists dysfunction , large area when not too thin , building envelope , indoor thermal environment and poor , there is an urgent need to use the building thermal environment and energy conservation for sustainable development theory to guide the development of the rural architecture . The status quo for rural construction of the Guanzhong area , this paper, the main research contents and results are as follows : ① Guanzhong rural construction survey , analysis of the current country building construction mode and structure characteristics , the trajectory of local farmers living and production way , research farmers functional space requirements of the country house ; ② typical residential thermal environment measured analysis of indoor thermal environment of the country house in winter and summer , the thermal environment of each room , analyzed the cause of the problem caused by indoor thermal environment ; ( 3 ) through the winter and summer subjective reflection of a survey of 30 farm house indoor thermal conditions , statistics farmers satisfaction rate on indoor thermal conditions , indoor thermal environment needs of rural architecture are summarized . The ④ farmers residential function space and indoor thermal environment needs of rural architecture optimization improvements . For the design of the building , the plane function space design should pay attention to the problem as well as suitable for off rural architecture and facade energy-saving design ; improved thermal insulation properties of the building envelope , building envelope thermal performance method ; for summer cooling , natural ventilation and cooling green building ; Finally, a country house in winter indoor heat source problem is proposed to improve the thermal environment of the Guanzhong rural architecture , not only to strengthen the insulation , but also appropriate to increase the an indoor heat source , suitable for Guanzhong rural residential renewable energy utilization . This paper argues that the reasonable building energy efficiency design appropriate to add the proper application of passive heating and cooling measures and renewable energy , to improve indoor thermal conditions on rural architecture , to meet the needs of farmers on indoor thermal environment .
