| Preface
A calculating tool for thermal system analyses in building physics, that takes interaction between building structure, building services, climate and the users into account, is of great interest both for the researchers and the designers in this area. In order to take the advantage of the graphical user interface, a unique library of software packages related to the basic building components, like layered wall structures with material data, boundary and surface conditions, ventilated space, windows, heat sources, HVAC components, etc. is made in Simulink, at the Department of Building physics, at the Chalmers University of Technology in Sweden, (Hagentoft, 2000).
During the same time, another building physics department from the Department of Civil Engineering from the Technical University of Denmark has developed a similar calculating tool, also in Simulink. Working with similar problems and using the same modeling tool, has brought an idea of joining the work of these two research groups. And even more, an idea of establishing a public available library of building elements that provide HAM system analysis in building physics.
The first step was to define the common platform in modeling, which would enable developing and exchanging models between the partners. For this purpose, we defined some basic blocks each representing one of the basic building constructions like walls, windows, ventilated space, etc, and the same data flow between them. For simplicity, only heat transfer was concidered. We also defined a common exercise for inter-model comparison.
The first results were very promising. Each partner developed its own library, with different blocks (although with the similar names), but the agreed data structure was strictly obeyed. By this, we succeeded in exchanging the blocks without any problems, just by dragging the desired block from one library and placing it into the model from another. The simulation results from the common exercise were also in a very good agreement.
All our ideas and results from this common work are presented in this document. At the same time, this document also defines guidelines for any future contribution to the library, including both models and the documentation of these. We believe that we are on the right way in establishing the International Simulink Building Physics Toolbox, and that this document will motivate other researchers to join us.
