The Analysis About Thermal Performance Of Bright Frame Glass Curtain Wall

With the fast development of economy, more and more glass curtain wall buildings have appeared in our city at present. On the one hand they have increased many gorgeous traits for the cityscape; on the other hand they also have lead to the huge waste of energy as a result of their worse thermal performance. It is obviously violating to our country's present energy-conserving development strategy.In order to have a deeper understanding to the glass curtain wall, this text attempts to start with the specific type of bright frame glass curtain wall, and studies its thermal performance about summer heat insulation and winter heat preservation. This text also wants to discuss the possibility of glass curtain wall to achieve energy-conserving goal by the study of construction feather, material procedure, and heat-transfer property and so on. In the analysis of this text, based on the respective characteristics of summer and winter, we put the emphasis on the shading in the study of summer heat insulation and the prevention of frosting in the study of winter heat preservation.The reason of this text study with bright frame glass curtain wall is: it is a traditional kind in the curtain wall; it has been used early; its technology is mature, its performance is the most reliable, and it has the universal general characteristic of glass curtain wall. Moreover, the constructional frame of bright frame glass curtain wall is directly exposed in the outdoor condition, from the thermal performance angle, it is also easier to engender the so-called thermal bridges and lead to more waste of energy. Therefore, this text hopes to reflect the energy-conserving development direction of all glass curtain wall industry from the study of bright frame glass curtain wall's thermal performance by definite study.By the study of this text, we can get more cognition of thermal performance of glass curtain wall from the research of bright frame glass curtain wall. Especially we can have a more understanding to its construction feather and characteristic of the shading in summer and the prevention of frosting in winter. In this way, we can have a effective way to improve the thermal performance of glass curtain wall and spur its sustainable development.
