Simulation based optimization process of the energy performance of a single thermal zone model
The present paper consists of a study regarding a problem-solving method called Simulation Based Optimization (SBO) applied to building energy performance. This method uses performance criteria prescribed by the Brazilian Technical Quality Requirements for the Energy Efficiency of Residential Buildings (RTQ-R) certification. The purpose is to investigate interoperability process of OBS through one zone model. This method opens the discussion on the process of building design whose quantification of performance parameters is no longer a factor of assessment and verification and becomes project criteria. The investigation of the processes was performed through low complexity geometric building with a reduced number of variables. It was possible to verify the effectiveness of the method used, which was successful in the solution search. The Rhinoceros and Energy Plus software have been integrated into the plug-ins and Grasshopper ArchSim and Goat engine optimization. The adopted efficiency indicator was the degree-hour for 26oC operating temperatures base. The solution from the optimization reduced the degree-hour by about 15% compared to the initial building. However, the temporal cost of simulation proved to be high whereas the simplicity of the model. The adoption process in a complete building still requires greater knowledge of the operating cost involved in optimization. However, the process already provides a glimpse of the performance evaluation of integration in the preliminary stage of building designs.
