夏热冬冷地区办公建筑节能改造设计研究

Research on Energy-saving Renovation Design of Office Buildings in Hot Summer and Cold Winter Areas

本文主要探究了夏热冬冷地区某办公建筑的节能改造设计方案。调查发现,该办公建筑一天之中8-18时能耗较高;一年之中夏季能耗最高,冬季次之;空调能耗在总能耗中的占比最大。基于实用性和经济性原则,选择建筑围护结构进行了节能设计,外墙方面使用EPS保温板,屋顶设计成种植屋面,外窗改造成真空玻璃窗和双层玻璃幕墙。结果表明,相比于原建筑,使用节能设计方案后外墙、屋顶和外窗的传热系数均有大幅度的降低,使得建筑保温隔热性能明显提升,达到了节能降耗的效果。

This article mainly explores the energy-saving renovation scheme of an office building in a hot summer and cold winter area.The investigation found that the energy consumption of the office building is high from 8 to 18 hours a day;The highest energy consumption occurs in summer,followed by winter;Air conditioning energy consumption accounts for the largest proportion of total energy consumption.Based on the principles of practicality and economy,the building envelope structure was selected for energy-saving design.EPS insulation boards were used for the exterior walls,and the roof was designed as a planted roof.The exterior windows were transformed into vacuum glass windows and double-layer glass curtain walls.The results show that compared to the original building,the use of energy-saving design schemes significantly reduces the heat transfer coefficients of the exterior walls,roofs,and windows,resulting in a significant improvement in the insulation performance of the building,achieving the effect of energy conservation and consumption reduction.
