A comparison between the software EUReCA and UrbanEnergyPro on a district in Germany

Abstract This work focuses on the development and assessment of the UBEMs (Urban Building Energy Models) of the Unterhaching district using EUReCA and UrbanEnergyPro. The two models have been developed by the Department of Industrial Engineering of the University of Padua and by the Renewable and Sustainable Energy Systems group of the Technical University of Munich, respectively. The primary goal is to compare how the two tools calculate heating and cooling energy needs and simulate building behavior. For this purpose a district of about 200 buildings, specifically Unterhaching, close to Munich has veen chosen. The comparison has been estimated on space heating, domestic hot water and cooling. This has been done by tweaking the input data of the two tools in order to make them as similar as possible. The simulations show similar evaluations for the energy demand for space heating while differences have been noticed for domestic hot water, although this energy demand is smaller than space heating. Energy demand for cooling has shown differences especially in non-residential buildings due mainly to latent load calculations, internal gains definition, windows areas definition.
