Abstract：Based on the literature research,the paper investigated the building layout,building structure and peripheral protection materials of existing farm houses in Yantai,summarized the typical forms of farm houses in Yantai,built a typical rural house model,and simulated it on Grasshopper platform to obtain the annual total energy-saving of the rural house model.With energy-saving and economic benefits as the goals of the renovation plan design,Octopus plug-in was used to optimize the comprehensive energy-saving transformation plan with multiple objectives,and economic transformation plans under different energy-saving rates were obtained.The results show that the energy-saving rates of the four kinds of economic transformation schemes are 39.0%,41.6%,45.5%,and 50.7%,respectively.The total investment cost is 12 566.2 yuan,13 739.6 yuan,15 157.1 yuan,and 18 775.8 yuan,respectively.The net present value rates are 9.2,8.9,8.8,and 7.8,respectively.This study can provide reference for the energy-saving renovation of rural residential buildings in Yantai.
