Connections from individual buildings and district energy systems will become increasingly integrated within smart grids to reduce energy and peak power and to increase occupant health and productivity. This poses new challenges for building simulation programs to support decision making during product development, building design, commissioning and operation.This situation leads to new functional requirements on computational tools for buildings that are not addressed by existing building simulation programs.

The aim of the project is therefore to transfer these developments to the buildings industry. For buildings and community energy systems it will co-ordinate currently fragmented developments on next generation computing tools based on two open, non-proprietary standards:

  • The Modelica modelling language
  • The Functional Mockup Interface

The objectives are to develop and demonstrate next-generation computational tools that allow building and energy grids to be designed and operated as integrated, robust, and performance based systems.
