Multi-objective optimization of cost and energy of residential buildings in Iran

Today, climate change and its move towards a gradual rise in global temperatures are of great concern and involve many aspects of people’s lives. In the meantime, particular attention should be paid to the resistance of building energy design to global warming, because over time, its economic and effective actions can be greatly affected by climate change. In this regard, this paper addresses the problem of finding cost-effective energy solutions and evaluating their resistance to heating and cooling loads using a multi-objective approach. In this paper, two scenarios of using solar panels and green roofs to illustrate the extent to which each of these technologies can play a role in reducing energy consumption are also explored in this paper. The building will be fruitful from the standpoint of cooling and heating loads. This article describes the characteristics of a residential building in Tehran. The proposed method involves optimizing the energy of the entire building and replacing the energy systems (solar panels and green roofs) that ultimately determine the optimal building components. The results of alternative systems show that the use of green roofs has a higher impact on reducing the energy consumption of the building under study.
