Abstract：

Envelope is an important guarantee for the realization of ultra-low energy consumption. The type and quantity of the building parts varies and demands the combination of corresponding technical requirements. There is no special energy saving design standards of the assembly building, therefore, the design process still follows the "Cold and Cold Areas of Residential Building Energy Efficiency Design Standards" (JGJ26-2010). In this project, based on the passive ultra-low energy consumption, the basic data of the performance of the envelope building parts are obtained through the research, the integrated principle of the building parts is taken as the research object and the multi-objective optimization analysis is taken as research method, comprehensively considering the benefits of energy consumption, material and cost as the optimization goal. And energy, material and cost factors are considered from the perspective of full life cycle, to determine the objective function, the constraint condition and the decision variables of the envelope building parts satisfying the passive ultra-low energy consumption demands, from the perspective of the material selection, construction mode, and heat transfer performance. The theoretical model of the relationship between product integration strategy and energy consumption is built through enormous simulation and statistical analysis to extract the energy consumption mechanism of envelope building parts of the ultra-low energy consumption assembly building, to study the design strategy of envelope building parts of the low cost and high performance assembly building, based on the passive ultra-low energy consumption demands. The research results provide a theoretical basis for guiding the design of energy-saving design and related standard of assembly building.
