【摘要】：以石家庄铁道大学基础楼为例,该教学楼为寒冷地区绿色建筑二星级运行标识建筑,分析了建筑2015年全年实际运行数据,得出单位建筑面积能耗为37.69kWh/m2,空调能耗和照明能耗约占整个教学楼能耗的85%左右,空调节能和照明节能是学校节能的重点领域,在此基础上构建了建筑能耗模型,分别分析了围护结构、空调节能以及照明节能潜力,得出围护结构性能提高对于降低建筑能耗并不明显,在优化制冷机组能效提高3.96的基础上空调能耗可降低7.89%,照明功率密度则可以降低建筑能耗11.10%,可见优化照明设计更适合于寒冷地区的高校绿色建筑节能.
[Abstract]:Taking the foundation building of Shijiazhuang Railway University as an example, the teaching building is a two-star operation logo building for green buildings in cold areas. The actual operation data of the buildings in 2015 are analyzed. It is concluded that the energy consumption per unit building area is 37.69 kW / m2, and the energy consumption of air conditioning and lighting accounts for about 85% of the total energy consumption of the teaching building. The energy saving of air conditioning and lighting is the key area of energy conservation in schools. On this basis, the building energy consumption model is constructed. The potential of envelope structure, air conditioning energy saving and lighting energy saving is analyzed, and it is concluded that the improvement of envelope structure performance is not obvious to reduce building energy consumption. On the basis of improving energy efficiency of refrigeration units by 3.96, the energy consumption of air conditioning can be reduced by 7.89, and the energy consumption of buildings can be reduced by lighting power density. It can be seen that the optimized lighting design is more suitable for the energy saving of university green buildings in cold regions.
