City development is a continuous renewal and change process, in the process of The new supersedes the old., how to treat the existing old buildings has become an urgent problem. Including included in the national historic site protection list also includes a large number of old buildings, the existing although still in the design life, but the function, appearance, facilities can not meet current needs, according to the ordinary old building regulations was not protected. With the development of the city is becoming more and more mature and saturated, how the old buildings to inject new vitality in the constraints of the existing old buildings, the completion of rebirth has become a hot issue in recent years attention. Jiangsu Yi run Building Renovation Technology Co Ltd General Zhao as we elaborate on the transformation of old buildings and the use of aspects.Reconstruction of Old Architecture OverviewIn western countries, the transformation of the old building and reuse has been a hot issue for discussion in the field of architecture, the 1979 Australian compiled "charter" has the cultural significance of local protection, referred to as "the Burra charter", for which protection of architectural heritage, clearly put forward the concept of "adaptive reuse", namely of a a place for adjustments to accommodate the new function. This approach because no weakening of the cultural meanings of place substantive and encouraged and promotion. The key to adaptive re-use is to find appropriate uses for historical buildings. In developed countries, the use of abandoned buildings (such as workshop, warehouse) conversion, the conversion to alternative space useful (such as commercial, entertainment, residential architecture) examples exist in large quantities. Reconstruction of Australian Liwilhelm Hozbaue architects designed Flakurm air defense turret, use of WWII existed in Vienna block 6 air defense turret are designed into the aquarium, galleries, museums and cafes.

The content includes the building space is perfect, the application of new components and materials and to adapt to the terrain of the curtain wall facade, in providing new functions at the same time, given the region's traditional landmarks of this common problem buildings make an important contribution.In China, the transformation of old building reuse has gradually been building community in saving cost and shorten construction period, save the benefits of urban texture attention, outstanding performance in the utilization of waste plant (Treasury) and school apartment renovation, the emergence of a number of outstanding engineering examples.Because of the transformation of old buildings of the reasons and advantages of the old building may be summed up as the following four points:1) economic factors. A building structure cost accounts for the total cost of 1/ 3, rebuilt than new can most of the money spent by the province, the main structure. At the same time, the transformation of old building reuse can reduce initial investment (including developers demolition, construction charge), the existing infrastructure base may continue to use. The construction period is short, can let the owners put into use as soon as possible to obtain greater profits, in the economy is very cost-effective.2) social cultural factors. Most of old building has its regional characteristics, is the process of urban civilization of the witness, they are involved in the process of civilization and progress, is the material carrier of history and culture in the area. We previously for historic buildings adopt methods as repair, and for those non historic buildings and historic buildings is weak method is adopted in the complete reconstruction of the new building.3) emotional factors. The old building was expressing history of urban development and continue to people, so that people get comfort in mind, people experience the history of urban development and human creativity in the presence of these old buildings, and the space and time form the framework of the cultural identity of space we live.4) environmental factors. The above environmental pollution 34% overall because of the construction industry in the construction and use of the process which, more than half of the world's energy consumption in the process of construction and use of buildings.Transformation of the old building techniques by exploring and nearly a century of development, transformation of old building reuse methods also varied. Modernism, postmodernism, deconstructionism art practices, minimalism, organic forms and so on in the old buildings have been trying. With the expansion of the Le Louvre Museum in France, Reichstag building renovation is successful, marks the modern practices in the use of old buildings on the maturation and dominant position. The following ways is the transformation of the old building common way.1) transform function. Use of the old buildings of the original space, change the original use functions, realize the dynamic preservation of the original architectural space. This method retains the original old building facades, update the internal equipment of old buildings and obsolete facilities, transformation into a modern facilities of the hotel, the Museum of art, the workplace.2) to break up the whole into parts. According to the new use functions of horizontal or vertical partition of the original large space, the formation of several small space, and then put into use. Mainly applicable to large space industrial buildings, single storey factory building, railway stations, warehouses and abandoned marina.3) the transformation of the structure. Proper reform for the structure of the original building, meet the new service function, make the structure is feasible, economical and reasonable.4) transformation of the expansion. Based on the original building structure or relationship with the original building close spatial range, to the original building structure appropriate expansion and additions, the old and new buildings to form a whole.双语对照
