BIM Technology Aided-old Office Building Exterior Insulation Energy-saving Reconstruction In The Case Of Zhengchang Office Building Facade Renovation

With the continuous development of city and update, a large number of building facing the competition of the new office building.office building of the early in the process of production and living use exposed a series of problems. One of the main reason is the material of the structure and construction method is not economic, cannot satisfy the requirement of sustainable development. By plane in old buildings and structures, on the basis of heat preservation and heat insulation by enhancing performance way, modify, open the window shade, avoid cold junction bridge and so on a series of reform measures to enhance the thermal performance of the existing buildings, avoid the waste of resources, reduce the "constructive disruption" of the city. At the same time in the process of transformation of envelope and external facade form of exploration and transformation to accord with contemporary aesthetic, promote the quality of the building.In this paper, on the basis of zhengchang office building design, study BIM technology aided by old building reconstruction design idea and method of exterior insulation and energy saving. Concrete structure is divided into two parts namely exterior insulation materials research and Revit in the concrete application and the remake of the possibility of cooperate with other platform software.The full text is made up of four parts. The first chapter mainly introduces the research background and meaning, research content, research purpose, research framework. The second chapter to introduce the design task and exterior insulation of the corresponding structure material aspects of the practice and the corresponding use case, through summarizing integrated use of zhengchang office building facade renovation to achieve the goal. This chapter first has been clear about the several problems needed to research, and according to these points in detail the relevant data and cases; Then sums up and summarizes the basic; Finally, specific to the case came to the conclusion. The third chapter for Revit in play a role in the whole process working the way pay attention to the point and cooperate with other platform software some of the specific usage and experience, and puts forward some prospects.
