Müller, R. Streblow et al Modelica Open source, object oriented modeling language for component oriented, multi domain modeling of complex systems Development initiated in 1996 by Hilding Elmqvist unify splintered landscape of modeling languages domain neutral modeling language integration of different domains Multi million investments in academia and industry (automotive, aerospace and chemical industry) Use with non commercial / commercial simulation environments (Modelica Association 8

6 Annex Objectives 11 Annex Objectives New generation computational tools based on non proprietary Modelica modeling and FMI standards as open source, documented, validated and verified computational tools to design and operate buildings, building systems and community energy grids as integrated, robust, performance based systems with low energy use and low peak power demand. Coordinate fragmented Modelica based development activities Create and validate "tool chains" that link Building Information Models to energy modeling, building simulation to controls design tools, and design tools to operational tools. Accelerate invention and deployment of integrated systems and performance based solutions for buildings and communities Reuse models across building life cycle (realization and persistence of design intent) Demonstrations include optimized design and operation of building and community energy systems 12

7 Motivation It takes years to implement new building systems and component in existing building simulation programs. Modern control systems cannot be adequately represented in building simulation programs. Building scientists use building simulators (DOE 2, E+, TRNSYS, ESP r), most of which are based on 30+ year old technology, controls engineers use more flexible design tools. Annex 60 bridges this gap by using a language that is used by many communities (Modelica), and through connecting legacy code using a standardized interface (Function Mockup Unit). 13 Motivation Reaching out to other critical communities for energyefficient buildings requires a multi disciplinary approach. Modelica and Functional Mockup Unit are technologies that are developed by multi disciplinary groups to bridge the gaps between mechanical engineering, controls, math, and computer science for design and real time control of complex engineered systems. Building Science makes use of this technology by developing component libraries for building physics, building services, building performance up to district simulation. 14
