Abstract
The paper takes a high-rise residential building in a severe cold region as an example,and analyzes its wind,light,thermal,and energy consumption environments with Phoenics,Ecotect,and DesignBuilder software.Green energy-saving measures were taken to restore the building in terms of architecture,structure,system,and equipment strategies,and the energy-saving rate and carbon dioxide emission reduction rate of the renovated building were predicted.The results show that in the diagnosis of the building performance,the wind speed of the building corners increases significantly,especially the wind speed of the upper outdoor floors and the top floors of the building.The indoor light is too low,and there is a glare problem near the windows.The performance of the target building has been significantly improved through the implementation of renovation measures on bay windows and exterior walls.In terms of the wind environment,the area of strong wind zone in winter and weak wind zone in summer have been significantly reduced.In terms of the light environment,indoor lighting has become more uniform,the percentage of illuminance index between 100 and 2 000 has increased from 9.2%to 32.7%,and the glare caused by illuminance of 2 000 has been reduced by 28.4%.After installing solar photovoltaic panels,the energy-saving and emission reduction rates has been as high as 19.8%and 38.8%respectively.Combining all measures,the final energy-saving rate and emission reduction rate of the target building are 54.3%and 86.3%,respectively.关键词
