Research on Passive Design Strategy of Low-Rise Residential Buildings in Cold Regions
With the rapid growth of new rural construction and continuous progress of living demand,the use and energy consumption of low-rise residential buildings are also growing.Energy saving design of residential building is particularly important.By investigating typical cases of low-rise energy-saving residential buildings and establishing basic model of low-rise residential buildings in cold areas,this paper analyzes the main influencing factors of passive energy-saving,and selects 11 passive energy-saving design parameters suitable for low-rise residential buildings based on envelope structure,exterior windows and ventilation.The energy saving contribution of each design parameter is quantitatively analyzed by using Designbuilder,which is a simulation software for building energy consumption.Orthogonal test and combined energy consumption simulation are carried out for the factors that have great influence on building energy consumption,and the optimal scheme of energy saving effect after combination is obtained.The purpose is to provide reference for how to design different building energy saving parameters according to energy saving potential in the design of low-rise energy-saving housing in cold areas in the future.
