The research on energy efficiency of residential building in Guangzhou

Nowadays, greenhouse effect and energy shortage are becoming more and more fiercely, the development of the green building is the necessary choice to building sustainable development. Building energy efficiency is one of the most important parts of green building, and the draft of Assessment standard for green building puts forward clear requirements for decreasing energy consumption just by improving the thermal performance of the envelop to get more score for declaring the green building label project. In view of the scale extending of the green building label project in the future, the paper studied on the energy efficiency design of the residential envelop in Guangzhou by investigation and simulation to achieve the decreasing ranges of energy consumption more than 10% of building energy efficiency standard value, and provided a technical measures for the energy efficiency ratio 60% just by improving the thermal performance of the envelop.
