Research On Energy-saving Renovation Technology For Existing Commercial Buildings In Northern Region

For energy saving technical reconstruction of existing buildings is important way to reduce building energy consumption, is also the important form of expression of circular economy. Huge stock of existing buildings in our country, and in the80’s and earlier buildings didn’t have any energy saving measures, has a higher shortcomings, poor thermal comfort and energy consumption, so for this part buildings that is still in used, energy saving technical reconstruction is imperative.With completion project of the commercial building energy saving-renovation under writer, reference to related research in this field at homeland and abroad,took the existed commercial building energy-saving renovation as the research object, demonstrated on both the necessity and feasibility of commercial building energy saving technology renovation, consider the energy saving-renovation technological can produce remarkable social benefit, economic benefits and ecological benefits, while significantly reduce energy consumption of existing buildings can also increase using comfort. All text divides into5parts:The first part is introduction, mainly discusses on both commercial building energy-saving technological transformation of the necessity and connotation. The second part mainly studies both at home and abroad to both commercial architecture implementation of energy-saving technological transformation. The third part mainly discusses on both the commercial building energy saving technical reconstruction principle and means. Presided over the fourth part combined with the author completed the projects of TESCO hymall store in Shenyang, examples the application of energy-saving technical reform in existing buildings. The fifth part is conclusion.Energy saving-renovation for existing commercial buildings is a comprehensive system engineering, involving the design, management, policies and regulations, construction and many other part, also relates to the construction technology, energy technology, bionic technology, intelligent technology, waste recycling technology. Moreover, the existing commercial building energy saving-renovation should respect the natural environment, should have the theory of ecological building, will be energy-saving technology is applied in every aspect of design, scientific design more in line with the development of the times, can meet the requirements of energy conservation, improvement scheme with high efficiency and energy saving effect, make the building energy saving up to newer heights and new depth.
