Research and Practice of Passive Low Energy Residential Design in Rural Areas of Semi-Urbanized Regions in Hot-summer and Cold-winter Zone

The applicability of urban building energy-saving ideas and technologies to rural house deserves reflection. It requires to clarify the key points for rural house energy-saving in theory and practical exploration. Principles of Rural Passive Low Energy Residence should be: passive technology preferred and make full use of local conditions, cope with specific comfort standards and moderately enhance envelope performance, optimize energy supply structure and technical benefits should be obvious with reasonable costs. This paper takes the rural house case study design in Yongsheng Village as an example to carry out the research. Based on the principle of “passive priority and active optimization”, the residential design makes full use of the potential of local microclimate, plane meets the living needs of winter and summer moderately improves the performance of envelope, takes wind tunnel as auxiliary temperature regulation system, and adopts distributed photovoltaic power generation system to provide domestic energy. The practice has achieved good operation results and obvious economic benefits. It provides an engineering example for the implementation of passive low energy technology in rural.
