This demonstrator application has been realized as part of the OGC Future Cities Pilot Phase 1.
Presented is a web-based application for assessing the estimations of solar energy production for roofs and facades of buildings. These values are calculated using a simulation tool developed by the Chair of Geoinformatics, Technical University of Munich, and the web application has been developed by virtualcitySYSTEMS GmbH. The building data is provided by IGN and Rennes Metropole, partner of IGN.
The simulation tool operates on CityGML based city models. By combining a transition model, sun position calculation, and an approximation of the sky dome, the solar power from direct, diffuse, and global sunlight irradiation are estimated each month. The shadowing effects are considered by applying a ray tracing approach. As a result each building surface is being enriched by its individual irradiation values. These are also aggregated to the building level.
Each sampling point from the simulation tool is parameterized with the simulation values and is transformed into a point cloud by virtualcitySYSTEMS.
