Research on Energy Consumption Characteristics and Reducing Measures of Near Zero Energy Consumption Office Buildings in Hot Summer and Cold Winter Regions
Zero energy buildings are an effective means to reduce urban carbon emissions,and high air tightness is a typical feature of zero energy buildings.Based on several studies on building air tightness measurement,this study summarizes typical air leakage paths in buildings and further analyzes the reasons for typical air leakage components in buildings by tracing the construction process.In addition,this article establishes targeted measures for building air tightness and applies them to practical cases.Finally,the improved building air tightness was measured,and the results showed that the air tightness range of the ultra-low energy consumption building measured was 0.13h-1 to 0.57h-1,with an average value of 0.32h-1.
