Multi-objective optimization method for seeking optimal reconstruction scheme of existing building

The invention provides a multi-objective optimization method for seeking an optimal reconstruction scheme of an existing building. Based on Morris sensitivity analysis, an NSGA-II algorithm, a BPNN prediction algorithm and a TOPSIS evaluation method, simulation software is used for simulating the energy consumption condition of a reconstructed building, prediction and multi-target optimization analysis of the generation effect of the building reconstruction scheme under multiple schemes are carried out, and therefore the optimal reconstruction scheme is obtained. Most studies have limited attention to thermal comfort after renovated building renovation, other constraint conditions in building renovation are not considered as a whole, reduction of carbon emission cannot be pursued at a glance, and the comfort of building renovation to the working environment of personnel is neglected. A virtuous cycle is formed in the building industry, the process of low-carbon transformation of existing buildings can be bett
