Potential and Economic Analysis of Office Building Energy Saving Reconstruction in Sunan Region

Abstract:

with the vigorous development of construction in our country, the proportion of the building energy consumption in total is increasing step by step, especially the 1980s existing buildings, the vast majority of them failing to take any insulation measures, the energy consumption of them is several times or even ten times to new buildings, therefore, in recent years, energy saving reconstructions of existing buildings have paid more and more attention. This paper takes a typical office building which was built in sunan region as an example, using some external thermal insulation materials such as rigid polyurethane foam plastics, polyurethane composite board and energy saving design software BECS to imitate energy saving reconstruction. Besides, the economy of each scheme of energy saving reconstruction was also analyzed. The results show that, energy saving reconstruction can greatly reduce the energy consumption of existing buildings, and bring good economic benefits, at the same time, it also can improve indoor comfort and working conditions, and can generate significant social benefits.
