Study On Integrated Energy Efficiency Retrofitting In Existing Residential Buildings Of Urumqi

Statistics show, the total quantity of non-energy saving existing buildings in Urumqi is approximately 70,000,000 square meters. After reckoning, the average energy consumption per square meter is about 37 kilograms standard coal. Those high energy consumption buildings all have the problem of heat and air leakage in the building envelope as well as low efficiency in heating system. If they do not carry out energy efficiency retrofitting promptly, they will consume massive energy and cause serious air pollution. However, even if the buildings are retrofitted, most of them only did enevlope retrofitting, few considered the heating system reconstruction. This lead to serious thermal waste and finally made the"energy conservation builings"save no evergy. Besides, enevlope retrofitting alone do not meet the need of housing comfortness. In view of the above problems, this article proposed the idea of"intergrated energy conservation retrofitting". At the same time, as to the current situation that we lack the experience of large scale of retrofitting and are experiencing the low speed in preliminary works, this article also analysized the exsisting building status in the whole city, as well as the typical residential building status, reconstruction plan, energy consumption and cost based on the Caochangxiang district energy-conserving retrofitting demonstation project. And also, the article has assumed the best way of intergrated energy efficiency retrofitting and the situation of the whole city after retrofitting, and finally obtained the suitable method and suggestion to the scaled retrofitting. Besides, it also give a scope and principle of the residential building retrofit to make sure that all work move smoothly.
