Study On The Relationship Between Rural Residential Building Form Design Nd Building Energy Consumption

The 14^th Five-Year Plan puts forward the grand goal of"speeding up the construction of beautiful countryside and completing the rural revitalization",and focuses on the protection of the rural ecological environment.The high energy consumption and extensive energy utilization of rural residential buildings have become important restriction factors for environmental protection.The building shape is an important index that affects building energy consumption.Scholars have carried out a lot of researches works related to building energy efficiency,but the existing researches are mainly focused on residential buildings and less involved in rural houses.Existing research is because of the building geometric abstraction,this ignores the construction of the complexity of the internal functions,divided form from function,thus exploring form elements and the relationship between building energy consumption when taking into consideration of the internal functional arrangement has more practical significance.Therefore,the research purpose of this paper is to take the rural residential buildings in the Chongqing area as the research object,to screen out the typical rural residential buildings in the Chongqing area,and to explore the relationship between the shape factors of rural residential buildings and the energy consumption of rural residential buildings under the premise of considering their internal function layout.Due to the large number of shape factors of rural houses,this study could not cover all the factors,and only focused on the two important factors of shape coefficient and the ratio of width to depth.First of all,through the field investigation of the rural houses in Chongqing and the reference of the new rural house promotion atlas,the author classifies the rural houses into three forms:rectangular,L-shaped,and U-shaped,and summarizes the typical functional layout characteristics of different forms of rural houses.Through field research,the structural characteristics,building materials,energy use mode and energy use habits of rural houses in this area are obtained,which can be used to set the parameters of energy consumption simulation in the later stage.Secondly,the author divided different forms of agricultural houses into 150m² and 200m²area sections according to the area local house style and the scale of rural houses.Under each area section,there are three types of rectangular,L-shaped and U-shaped houses respectively,and each type contains multiple house types.The energy consumption analysis was carried out through Designbuilder energy consumption simulation software.Finally,the correlation analysis method was used to summarize the above-simulated data and the relationship between the body coefficient,the ratio of aspect width to depth and energy consumption of rural houses.This study concluded that farmhouse,the energy consumption is not the shape coefficient is smaller,the lower the energy consumption,farmhouse,the overall level of energy consumption and use energy consumption of the front of room and contact with the outside appearance of the size of the area,and proposes the appearance of the room area coefficient concept room to evaluate energy consumption,that reduces the overall energy consumption of farmhouse should minimize the energy consumption coefficient room appearance.
