The Establishment of Exterior Windows Energy ...

The exterior windows are the weakest links of heat insulation in building envelop. The evaluation of the windows energy-saving is an important research topic. This paper respectively used the fuzzy comprehensive evaluation method and grey correlation evaluation method to evaluate, from the results can be seen, both of the two methods have some significance in the actual windows energy-saving transformation. But the disadvantage of these methods is that influenced by the subjective factors. By contrast, the grey correlation evaluation method is objective and it is more suitable to evaluate the windows energy-saving.
