Abstract：In order to determine the influence of key parameters of the envelope design of ultra-low energy consumption high-rise residential buildings in hot summer and cold winter areas on the energy consumption of the buildings,and to optimise the range of values of the envelope,a typical ultra-low energy consumption high-rise residential building in the area is selected as the research object,and a benchmark model of ultra-low energy consumption building is established by using the PKPM software,and the heat transfer coefficient of the external wall,the heat transfer coefficient of the roof,the heat transfer coefficient of the external window,and the ratio of the window and wall in the north-south direction are selected as the influencing factors for the energy consumption simulation.The energy consumption simulation is carried out with the energy consumption value of ultra-low energy consumption residential buildings as the constraint target,and the sensitivity analysis of the influencing factors is carried out through the energy consumption simulation results,while the control model of high-rise residential buildings with different numbers of floors is adopted to verify the experimental conclusions.The ranking of key parameters of envelope design on building energy consumption and the reliable parameter selection range are obtained.
