A Study on Comparison of Building Energy Simulation and Measurement Results for a City Hall

Abstract

In recent years, the number of public office buildings which were built by the glass curtain wall increased rapidly, but through the results of the investigation of the government, these buildings have been found that the heating and cooling load is high, and showed low energy efficiency. So in this study, through energy simulation, the energy consumption of public office building was verified and measured; environment data and calculated data were compared to make more precise simulation. The heating and cooling load was calculated via EnergyPlus; building was modeled by Google SketchUp connected to EnergyPlus. The results of this study were as follows: in simulation, incident solar radiation from large curtain wall should be underestimated. And using site-measured outdoor environment data can increase accuracy of simulation result.
