Abstract：
Building envelope trade-off option is the way that through calculating and comparing the annual heating and air-conditioning energy consumption of the design building and the reference building, then judging whether the overall thermal performance of building envelope is up to the design standard of energy efficiency , lastly, the energy efficiency design parameter of building thermal can be decided. Two types building are almost the same except in the design parameter of building thermal，but they ought to adopt the same efficiency of air-conditioning and heating system, therefore the trade-off option can use the load as a criterion instead of using energy consumption. As compared with trade-off based on energy consumption, to use the trade-off based on load can directly appraise the overall thermal performance state of building envelope, thus energy efficiency property of the building thermal design can be directly judged.
