Dynamic Simulation Methodologies for Urban Energy Demand

Abstract

This paper presents a new dynamic physical energy model of building for simulating the energy demand of cities. Firstly, a justification it is given regarding the necessity of a new building model and the advantages of using modular building simulation when dealing with large numbers of buildings in an urban context. The main motivation was a flexible and very modular interaction of 3D urban geometry description with the CityGML data format and energy related attributes for building parts. The paper then presents the modular dynamic building model and its validation with a real case of study for single buildings. The model integration into an urban modeling platform named SimStadt is explained with the necessary input data for a city heat demand calculation.
