Enhanching energy applications through semantic 3D city models and open data
Summary
Urban Building Energy Modelling (UBEM) refers to the techniques, methods and software tools used to simulate the energy performance of buildings at several scales of analysis. However, UBEM is heavily dependent on detailed, high-quality data—a challenge compounded by the limited availability and fragmentation of open data sources. In our research, we use semantic 3D city models (s3DCMs) and open data to enhance urban energy applications using as case of study The Netherlands.
Our research is split into two main elements: first, the creation of the corresponding dataset that aggregate the multiple open datasets into a s3DCM enriched with energy-related data. Second, the creation of in house software tools to perform energy simulations such as solar analysis and energy performance of buildings.
Output
CityGML-based 3D city model testbed for energy-related applications
This repository contains a open testbed for energy applications based on the CityGML v2.0 standard. The study area is located in the municipality of Rijssen-Holten (circa 38.000 inhabitants, corresponding to circa 23.000 buildings) located in the eastern part of The Netherlands.
