The Study On The Application Of Climate Adaptation Window In Hot Summer And Cold Winter Area

Window is the weak link of insulation and the key of energy-saving. For the two of extreme zone in hot summer and cold winter zone, solar radiation is one of the most important factors of the poor indoor environments. On the summer of excessive- solar radiation, Single- glasses can't shelter the entry of heat radiation, if adding the sun visor ,the shortcomings is that light and beneficial sunlight in winter will be shielded. Obviously, the same kind of glass,single shade can not meet both "shading--blocking the summer solar radiation" and "access to sunshine in winter --make the best use of solar radiation heat gain" needs. Therefore,the window should meet the bidirectional requirements of the building performance on solar radiation in this zone, adjustable window should be the most appropriate of this. Nowadays, energy-saving become a focus of the building design , scientific and effective energy-saving design to the window is a universal concern.According to the climate features in Wuhan and the sun altitude angle changes in the use of rules and principles of light reflection, this text start analysis form the design aspect,technical aspect and economic aspect of the window in hot summer and cold winter zone, propose the concept of Climate Adaptation Window and and its application instance.The main idea is use of window's accessories reflect the light and thermal radiation back to the sky in summer, move the attachment or adjust its angle so the light and heat can be reflected into the room in winter. After making full consideration of all the factors that impact the parameters of Climate Adaptation Window, such us the tend of shading effect of change , thermal parameters of windows, architectural aesthetics, design and construction, then design the program of different direction of Climate Adaptation Window and its thermal performance parameters, establish the computer mode and do simulate and analysis to the Program , Comparison the Difference in Energy-saving effect of the General window and the Climate Adaptation Window, obtained the impaction and advantages of the Climate Adaptation Window, generalize a varies of design strategy about the window for the solar radiation which can guide architectural design.This research is a demonstration project on construction of renewable energy application supported by ministry of finance and construction ---the Conversion Engineering of the School of Architecture and Urban planning in Huazhong University of Science and Technology. The start of the text is the concern of Energy-saving window and study of new window,the way of the study is experiment and quantitative methods,the result not only have considerable significance but also provide trendy ideas and inspiration to the architect.
