More and more cities are creating and adopting three-dimensional virtual city models as a means for data
integration, harmonisation and storage, often based on CityGML, which is an international standard
conceived specifically as information and data model for semantic city models at urban and territorial scale.
A centralised database can thus foster the development of new integrated applications profiting from such an
harmonised data source, in that detailed information is retrieved about building characteristics or any other
relevant entities needed for urban planning (infrastructures, hydrography and terrain models, etc.).
This paper focuses on the adoption of a CityGML-based semantic 3D virtual city model to perform energy
simulations. It deals primarily with the demand side, and concentrated particularly on the spatial and
temporal evaluation of the net energy demand for space heating of buildings in a city.
Two approaches are presented: the first one deals with the estimation of the heating energy demand of
buildings adopting a standard-based approach, which allow obtaining monthly values of heating energy
demand. The second approach describes the first results as how a dynamic simulation tool can be connected
to a CityGML-based city model in order to benefit from the amount of harmonised data stored therein and
further refine the results, e.g. in terms of time resolution.
As test area, a part of the city of Trento (Italy) was chosen.
