IBPSA Project 1: BIM/GIS and Modelica Framework for building and community energy system design and operation

Project Details


IBPSA Project 1 will create open-source software that builds the basis of next generation computing tools for the design and operation of building and district energy and control systems. It extends work conducted under the IEA EBC Annex 60. All work is open-source and built on three standards:
-IFC for data modeling at the building scale,
-CityGML for data modeling at the district scale, and
-Modelica for modeling the performance of building and district energy systems.
The project will be conducted from summer 2017 to summer 2022, performing the tasks outlined in the workplan.
