Hybrid Approach For Building Envelope Optimisation Using Genetic Algorithms And Simulated Annealing

Piyush Varma, Bishwajit Bhattacharjee

Abstract: Optimisation of building envelope for thermal performance is a complex problem involving a multitude of variables. While the combinations of variables lead to a vast dataset of discrete points forming the feasibility domain, the optimal solutions are only few and difficult to discern. The objective is to develop a methodology using a hybrid approach involving both Genetic Algorithm (GA) and Simulated Annealing (SA) approach to optimise the building envelope with respect to thermal performance. The GA and SA are complementary algorithms. The methodology uses the advantages of both these methodologies to improve the solution. The outcome indicates that Hybrid (GASA) approach improves the reliability of solution. While there is minor improvement in solution quality Hybrid (GASA) approach achieves the optimal frequently.
