Apllied Research Of Passive Energy Saving For The Architecture Exterior Wall In Zhengzhou District

In China, the energy consumption of architecture industry has already attend30percent in the whole society’s consumption nowadays. What’s more, the proportion is getting higher and higher with the rapid development of urbanism. The majority of the architectures are just passively take the lowest energy saving standard of insulation design.Otherwise ignoring the request of energy saving standard, just focus on the figure of architectures, leading to a reality which make heavier energy consumption. As a main element of the maintenance part of architectures, the exterior wall is taking an insignificance function in the architecture design. It is really important to take an appropriate method to solve the energy saving problems of exterior walls, making sure to satisfy the environment request of indoor room and to induce the energy consumption of architectures.Starting from the angle of passive energy saving, the issue of the research focus on the thermal capacity of the exterior wall. The essay discusses how to make the appropriate designs to improve the efficiency of the exterior wall getting used of the wind, light and thermal, to make the indoor space more comfortable as well as to reduce the consume of the energy. While researching, the essay does endeavor mainly on two aspects. On the one hand, it takes an arrangement of the meaning of "passive energy saving of exterior wall" and several influenced factors. First of all, it talks about the geographical and the climate factors which decide the main energy consumption characteristic, the face direction of the exterior wall and the relationship with the perennial wind’s direction. What’s more, it talks about the range of the architectures which can be used for the passive energy saving together with the economic and the technology factors which related to the final result of energy saving. It also talks the influence of other factors to the whole plan of the architecture group and the single design, which bring the principle for the passive energy saving design. On the other hand, by analysis the thermal capacity of exterior wall, the essay do researches from differ aspects range from insulation, nature lighting, nature ventilation and so on. Combining with huge amount of instances, the essay give a clear arrangement of methods to different energy saving effect.Consequently, taking a real project which the writer have already join the design process as an example, the essay discuss the design methods of getting used of passive energy saving of exterior wall to attain the aim of final energy saving. It offers the theory basis as well as clue the direction for the real design tendency of localization passive energy saving design of exterior wall in Zhengzhou city.
