| In recent years, the "double skin" architectural form appears in China. Because of the energy crisis, keeping energy and low-carbon have become the focus of attention, designers are keen to design "double skin" construction. However, not all of the double-skin construction to energy saving can be up to the real requirements. In theory, the purpose of saving energy can be achieved outside the skin layer generally refers to the form of "breath-able" type wall, that is, double-skin glass curtain wall. This wall is designed to organize the flow of air inside the building, according to well-designed building space air circulation system to provide better ventilation in summer heat and winter insulation, which has become "double skin" glass curtain wall a common feature in EuropeBecause of its excellent energy-saving features, the "double skin" building has become a hot topic. However, whether this theory can be energy-efficient "breath-able" type glass curtain wall in the actual project can really achieve the energy saving effect? This "breathing" air curtain is suitable for hot summer and cold winter region? Double skin wide range of curtain wall, in addition to "breath-able" type wall, as well as many forms of double-skin system, and some is due to load-bearing needs; some is due to the reasons for building function; there is a majority of double-skin curtain wall construction is designed only as aesthetic needs, only formal expression, which "may be breathing" walls of the cost is relatively expensive, the investment costs are high, about double the domestic architecture of the epidermis is not a lot of information is not comprehensive. Thus, in the design, because a large number of domestic designers do not quite understand this knowledge, can not be correct and reasonable used in the double skin form their own designs; in the epidermis and varied forms, can not quickly location more conducive to the needs of the skin form of energy, and save the project expenses. Form of double-skin curtain wall allows us to better understand the "double skin" knowledge of all aspects of construction, so designers can better choose the appropriate form, not just from the skin form of building up the design, construction and beautiful in ensuring at the same time make the building more comfortable, to make better designs.Hangzhou lies in hot in summer and cold in winter zone in China, the main cases in this paper are mostly from Hangzhou. By researching, the author analyses whether hot summer and cold winter region is suitable for double-skin curtain wall, so as to achieve energy saving purposes. The first chapter of the article is mainly introduction part, for the study background, purpose and meaning to do the analysis; second chapter focuses on the history of double-skin, and the research situation at home and abroad; third chapters are key sections, where the double sum layer of the epidermis of the common type, double skin problems and some common-sense analysis of the foreign cases; Chapter for Hangzhou to study, to investigate the hot summer and cold winter zone status of double skin construction with energy-saving analysis; the fifth chapter is primarily a designed case of double-skin building, me an while, it also introduced some design process of double skin wall which can breath. |
