Optimization Of Energy Saving Measures For Glass Curtain Wall Of Super High Rise Buildings In Guangzhou

In super high-rise curtain wall buildings,the energy consumption of air conditioning and lighting accounts for 60%-80% of the total energy consumption.The glass curtain wall and shading system,as the energy-intensive part of the envelope structure,play an important role in building energy conservation.In the hot and humid climate of Guangzhou,due to the strong influence of solar radiation,the configuration of glass curtain wall and shading system has contradictions in cooling and heating energy consumption and indoor lighting and lighting energy consumption.The optimal configuration of glass curtain wall and shading system has not yet been Get a good solution.The purpose of this article is to use the Design Builder simulation software to conduct a case study of a typical super high-rise office building in Guangzhou,to discuss the configuration of the building’s facade facing the upper curtain wall glass and shading measures to minimize heating,cooling,and lighting energy consumption.The author provided guidance and advice on the early design of glass curtain wall buildings in Guangzhou.The research results show that only the building’s shading methods are optimized.Horizontal shading is installed on the south facade of the building,and automatic louver shading is installed on the east and west facades.The comprehensive energy consumption of cooling,heating and lighting throughout the year can be saved by 0.31%.Through optimized combination,the annual comprehensive energy consumption can be saved by 2.20%-2.99%.
