The Study On Energy Consumption Of External Window Of The Passive Ultra Low Energy Consumption Residence Green Buildings In Inner Mongolia

The energy crisis is serious.In order to reduce the building energy consumption and the total social energy consumption,this project focused on the specific meteorological parameters in Inner Mongolia,mainly studying the residential buildings in the cold C area,and taking Hohhot city as an example,introducing passive ultra low energy consumption green buildings in this area.Taking actively use of the natural resources to reduce the building energy consumption in air conditioning period and heating period.Project research using on-site visits and field research methods,the collection and analysis of energy consumption data of some new residential areas in recent years are carried out in this area.Using the numerical calculation method to analyse that the external window is the building parts,on the premise of meeting the requirements of building lighting,which is most energy-consuming in existing buildings.Therefore,we research for the external window in passive ultra low energy consumption green buildings.This project focuses on the external windows of passive ultra low energy consumption green building,which is the main energy dissipation components in peripheral protective structure.According to the computational formula of Solar Heat Gain Coefficient(SHGC)and the current standard,we get the winter ratio and the summer ratio of window frame by using the method of numerical calculation.The maximum ratio of window frame in winter and the minimum ratio of window frame in summer are studied.We know that the ratio of window frame is a calculated value which is related to the correlation coefficient such as solar radiation absorption coefficient.We also know that the maximum ratio of window frame in winter is an effective value and the minimum ratio of window frame in summer is an invalid value,so we need use the shading facilities for passive ultra low energy consumption green building design in summer.For reducing the heat quantity of the room in the summer,taking the summer solar radiation as the main reference standard,the suitable sun shading facilities for residential buildings in this area are studied.Synthesizing the winter ratio and the summer ratio of window frame,draw the curve of the heat of the solar radiation with the change of the external window area,scheming out the best external window system for the passive ultra low energy consumption green buildings which is suitable in Hohhot area.To further verify the accuracy of the conclusion and increase the region applicability,in the eastern and Western Inner Mongolia,two cities,Tongliao and Wuhai,are selected as representative cities for verification Establishing models in the above two regions by using the method of analogue energy consumption analyzing,we can conclude that the designed external window system has an ideal energy saving effect in two areas.For achieving better energy saving effect,taking the Hohhot area as an example to establish a model which is based on the study of the external window system in order to introducing the passive ultra low energy consumption residence green buildings in Inner Mongolia area.We can analyze that the feasibility and energy saving performance for the passive ultra low energy consumption green buildings in Inner Mongolia.We will give a hand for choosing the external window of the passive ultra low energy consumption green buildings,and provide the basis for the formulation of the related standard for the passive ultra low energy consumption green buildings in Inner Mongolia.
