既有公共建筑圍護(hù)結(jié)構(gòu)綠色改造技術(shù)研究
[Abstract]:With the further development of green buildings, the green transformation of existing buildings has become the object of attention and research. There are many public buildings in our country, and the building energy consumption is large, which has a great potential for green transformation. The envelope structure, as the partition interface of the building interior and exterior space, is the key point of the green transformation. In this paper, the green transformation of the outer envelope structure mainly includes the improvement of its aesthetic performance and thermal insulation performance. Through a large number of completed cases of public building reconstruction, it is found that due to the limitation of experience and technology, the aesthetic and thermal insulation properties of the enclosure structure are often severed during the transformation. One is to pay attention to the improvement of thermal insulation performance, neglecting the place feeling of the existing public buildings, which leads to the lack of urban context; the other is to attach importance to the transformation of the building image and ignore the improvement of its thermal performance. The target of energy saving and emission reduction has not been reached. In view of the deficiency of the above research, this paper puts forward the green transformation design strategy of the aesthetic performance and thermal insulation performance of the outer enclosure structure. This paper mainly carried out the following work: 1, through consulting the relevant research documents of the existing building envelope structure at home and abroad, and investigating the application status of the existing public building envelope structure in our country, and calculating its thermal performance. In this paper, the problems of aesthetics, thermal engineering and construction technology in the reconstruction of the existing envelope structure are summarized and put forward. The research goal of the green reconstruction of the envelope structure is established, and from the point of view of improving the aesthetic performance, the research goal of the green transformation of the envelope structure is established. Based on the investigation of a large number of cases at home and abroad, this paper discusses the influencing factors and principles of improving the aesthetic performance of the enclosure structure. At the same time, this paper puts forward the retrofit design strategy and method of improving aesthetic performance based on different types of exterior envelope structure. From the point of view of improving thermal insulation performance, the transparent envelope structure and opaque envelope structure are designed from two aspects of heat preservation and heat insulation, respectively. This paper discusses the modification design strategy of improving its performance, puts forward the technical measures and construction methods of the envelope structure with different parts and different construction practices, and makes use of the Designbuilder simulation software. The energy saving effect of different shading forms in different orientation is analyzed quantitatively. In addition, the application strategy of solar photovoltaic in the reconstruction of enclosure structure is also discussed, in order to alleviate the energy crisis, Based on the theoretical research on the green transformation of the outer enclosure structure, the environmental pollution is applied to the renovation project of the government office building in Ju Huangmiao Town, Jinan. Through field investigation and thermal test, this paper analyzes the problems existing in the aesthetic performance and thermal insulation performance of the envelope structure, and optimizes the green modification scheme of the outer envelope structure, and analyzes the problems before the transformation through software simulation. The result shows that the energy saving effect of the building is remarkable, which plays a positive role in promoting the reconstruction of existing public buildings in Shandong area, realizing energy saving and emission reduction, and improving the image of the building.
