Abstract:Whole building energy analysis is simulating a building’s energy consumption based on building properties, function properties and weather data. This research is aimed at pinpointing the relationship between the level of detail of a building simulation and the accuracy of this simulation. This is done by running 72 simulations in EnergyPlus, varying level of detail over two axis. The geometry and material properties are varied, and the installation properties are varied. This was done with the Epi Drost building in Enschede as a reference building with benchmark data. Analyzing the results, an obvious relationship between level of detail and the accuracy of the building energy simulation could not be found, but insight was gained into the correlation between installation setup and building geometry in energy simulations. It can be concluded that the increase in accuracy gained by more detailed geometry and zoning is highly dependent on the type of HVAC simulation used to simulate the building.
