IEA EBC Annex 60

The IEA EBC project Annex 60 led to open-source, freely available, documented, validated and verified new generation computational tools.These tools allow buildings and community energy grids to be designed andoperated as integrated, robust, performance based systems with low energyuse and low peak power demand. The developed tools are all based on threenon-proprietary, open standards: Modelica, Functional Mockup Interface (FMI) and Industry Foundation Classes (IFC).
