Simulation based optimization process of the energy performance of a single thermal zone model
The present paper consists on 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 phase
of building designs.
