Analysis On The Application Of External Shading Forms Of Exterior Windows Of Office Buildings In Zhengzhou

With the continuous development and expansion of China's urbanization,the completed area of the building industry in China increases year by year.However,with the booming development of China's construction industry,the proportion of building energy consumption in China will gradually increase to about 40% in the future,ranking first in China's social energy consumption.Therefore,building energy conservation has become the primary task of the whole society.At the same time,the proportion of non-energy-saving buildings in the country has reached more than 90%,so building energy conservation has become an important measure that the national people need to pay great attention to.Building Windows and doors are important nodes of building energy saving loss,so building shading is one of the important measures of building energy saving.With the steady development of China's economy,the proportion of office buildings is increasing year by year.Compared with other types of buildings,office buildings have a high concentration of people,a long service cycle,and a huge annual energy consumption of buildings.Moreover,users have a very high requirement on the comfort of indoor office environment.Taking Zhengzhou as an example,this paper studies and analyzes the forms of shading outside the Windows of office buildings in cold areas and draws a conclusion,which is of great significance for reducing the energy consumption of office buildings in Zhengzhou,improving the indoor lighting of office buildings,and improving the indoor thermal comfort of office buildings.In this paper,the building energy consumption simulation software DeST-c and Ecotect were used to establish the office building model in Zhengzhou.Three typical forms of external shading were selected for the south and west Windows of multi-storey office buildings for simulation calculation,and the effects on building energy consumption,indoor natural lighting and indoor natural temperature were studied.A comprehensive analysis of the south and west Windows of office buildings in Zhengzhou suitable for external shading forms,and the Zhengzhou office buildings outside the window shading application optimization analysis.
