Estimation on Representative Plane Dimension of Rural Residential Buildings at Regional Scale

摘要

The construction of a representative geometry model of residential building at regional scale is a basic work to estimate building energy consumption and establish new policies for building reconstruction. However, the research on how to build representative geometry models for rural residential buildings at the region level is still neglected. Such a problem considered in this paper provides a method to build a representative two-dimension plane model for rural residential buildings in a certain region. There are three basic steps in this method. First, building lengths and building widths of residential buildings in a certain region are acquired with Google Earth. Secondly, frequency distribution statistics for the acquired data of building lengths and widths is conducted. If similarities between them are shown through frequency distribution charts, the third step can be continued. In the last step, K-mean value cluster analysis, a statistics method provided in SPSS software, is utilized to estimate the representative building length and building width at regional scale. To show more details about this method, the region of Jiaxing in China is taken as a case to obtain the representative two-dimensional plane model. In the future, representative 3D models for rural residential buildings at regional scale will be further explored.
