Taguchi Method-based Optimization Design of Indoor Thermal Environment of Traditional Dwellings in Cold Regions
Exploration into optimization design scheme for the indoor thermal environment of traditional dwellings in cold regions carries great significance for the inheritance and development of traditional architecture. With traditional dwellings in Qingcheng Ancient Town in Lanzhou as an example, through actual measurement of temperature and humidity and Ecotect Analysis software simulation, the main factors affecting indoor thermal environment were identified and used as the basis for selecting the optimization factors of Taguchi test. After selecting the appropriate optimization target and optimization factor, the optimization factor was subject to level analysis to determine appropriate optimization level and then establish factor level table. The appropriate orthogonal table was selected for Taguchi test based on the number of factors and levels, and the average value of the test results was analyzed to finally derive the optimization design scheme. According to simulation verification, the Taguchi method-based optimization design scheme reduces the annual energy consumption per unit area by 67.7%, which can provide a reference for the optimization design of the indoor thermal environment of traditional dwellings in cold regions.
