In order to get the optimal solution in the multi-objective decision-making of renovation, the study proposes a class of improved grasshopper optimization algorithm s . The process employs a systematic methodology to identify an optimal energy renovation method, taking into account the specific characteristics of the building environment. It then classifies and formulates the energy reduction substitution items for building renovation, and finally, it synchronizes the cost of the renovation project as a measure for decision-making. The elite inverse strategy approach enhances the grasshopper optimization algorithm to facilitate the multi-objective decision-making process associated with building renovation measures. The results show ed that the improved grasshopper optimization algorithm c ould achieve a decision accuracy of 98.8% for the test samples, which wa s 5.5% higher than the accuracy of the particle swarm optimization algorithm. Repeated run tests of the research algorithm for multi-objective decision making yielded a mean decision fitness value of 2.34×10 4 and a data extreme value of 0.38×10 4 . Compared to other algorithms improved grasshopper optimization algorithm converged in a lower range of fitness values, which indicate d that the algorithm work ed well for multi-objective optimization and the model repeatability wa s good. The research algorithm was used to decide the energy efficient renovation planning of the building and the power consumption of the renovated power supply system was reduced by 23.7%-49.6%. This indicates that the renovated building has better energy efficiency and can provide a reliable technical direction for decision-making optimization of building energy efficiency renovation. }, pages = {1058--1067} doi = {10.61435/ijred.2024.60483}, url = {https://ijred.cbiore.id/index.php/ijred/article/view/60483} }
