Abstract

Simulation-based optimization (SBO) processes can enhance building performance. The combination of OBS and machine learning methods appears as an alternative, capable of reducing the computational cost of the process without losing the robustness of the solutions. This study used artificial neural networks associated to a single objective SBO process to minimize the energy consumption with cooling, heating, and lighting systems in an office building through modifications on the building envelope. The results showed a significant reduction in the computational cost, in situations that the reduction of up to 50% of simulations.
