Abstract: This article draws a comparison between the described approach and a single-zone modelling approach with fitted parameters. The fundamental differences – accuracy, simulation times, preparation effort – of the modelling strategies are discussed. A multi-zone approach to model existing buildings within the scope of district simulation for the implementation of refurbishment projects is presented. It incorporates the geometrical simplification of the building body and rules to distribute thermal zones. Afterwards the simulation model is generated automatically from a database that holds the building information. A case study contrasts both methods by applying them to buildings of a university campus.
