The right BIM Solution

HESMOS

Our buildings' energy consumption is becoming increasingly important under the aspect of a sustainable development. At the same time demand for a higher quality of living is increasing. If nothing else, the investment and operating costs will decide if a project will be realized or not. Optimizing to that end will start in the early design stages already. Influencing factors are a building's location and orientation, as well as the used materials, the way of constructing, the heating and ventilation system among others. Using Building Information Modeling provided an ideal data basis for this complex design task. All the different aspects that have to be considered for the design decisions can be incorporated in a model and can be simulated using various criteria.

The research project HESMOS combined using Building Information Modeling with building automation. A virtual energy laboratory was developed to be able to take a holistic view of a building's design. It was the goal to bring down the input and controlling efforts significantly. In order to do so, the architectural, the structural and other engineering models were used in the process and their data quality was validated. Missing information could be added using extensive construction and material libraries.

In the HESMOS project AEC3 was responsible for the specification of the building model data. With the know-how built up in previous projects like InPro and also by cooperating with the Center for Integrated Facility Engineering in Stanford, AEC3's focus was on the identification of relevant data exchanges at first. In order to get the so-called exchange requirements, the processes and the data requirements had to be identified and analyzed. This research's results were mapped to a BIM data structure - in this case the open standard IFC. By doing this, all the relevant data was combined within a subset of the IFC model, a so-called model view definition, where additional information could be added. This technical specification could then be used for the software implementation and also for data quality validation. In this case the new mvdXML format was used that was developed during the MEFISTO project.
