Analysis of Passive Energy-saving Potential of Existing University Dormitories in Cold Areas:Taking Nankai University Balitai Campus as an Exmple
Taking the dormitory of Nankai University Balitai Campus as an example,the potential of passive energy-saving renovation of existing university dormitory buildings in cold areas under the background of low carbon was explored,and through field research,benchmark simulation was established,and Grasshopper software was used to build a parametric platform to simulate and analyze the passive energy-saving factors of the thermal performance of the outer envelope of the benchmark model,designed orthogonal tests,simulated building energy consumption in different tests,and analyzed the relationship between parameters affecting energy consumption and energy consumption through SPSS.Therefore,the degree of influence of each parameter on building energy consumption is determined,and the sensitivity of different factors to building energy consumption is obtained.The results show that the heat transfer coefficient of exterior walls,roofs,exterior windows and other parts have a linear relationship with heating and cooling energy consumption.The priority of energy conservation is:exterior wall,exterior window,roof;with a maximum energy savings potential of 61.9%just by changing the thermal performance of the envelope,achieving zero energy consumption requires energy-efficient active equipment and maximizing the use of renewable energy.
