Testing Work

With the deepening of the energy conservation of the building, energy saving from the original design of building energy-saving gradually turned to the field detection and completion acceptance, which requires a corresponding energy-efficient means of detection. With the development of infrared technology, the combination of infrared technology and detection methods of building energy-saving, to further promote the development of building energy efficiency testing work. Compared to the traditional heat flow meter or hot-box method, infrared thermal imaging method has no effect on the measured object, detecting the surface temperature of quick reaction speed, accompanying with wide temperature range and high precision, is widely used in various fields of testing work, which has been particularly prominent in the thermal defect detection. In this paper, the method of infrared thermography is used to confirm whether the thermal defects exist in energy-saving construction or not. Testing results show that infrared thermography can accurately reflect the temperature distribution of building wall surface. Infrared thermal imaging to detect the building surface's energy efficiency, which is providing efficient and accurate means of detection for the evaluation of the building energy efficiency. This is to help carry out a comprehensive building energy-saving testing.

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.
