The rising requirements on building performance in terms of energy- and resources efficiency result with increasing complexity of design and planning process. The consequence is a large number of planning process stakeholders working with different models and tools, numerous simulations and increasing data-flows. New methodological approach and tools for design and construction process is necessary, in order to provide for more efficient communication and information management. BIM (building information modeling) as tool as well as method promises enables high level of integration and therefore management of complex data and information loads. Research shows that for successful realization of complex projects such as sustainable buildings are, is not only implementation of innovative technology, but also design of planning network necessary.

This paper will present a case study of BIM-use for design and life-cycle optimization of energy efficient industrial facility within research project INFO (Interdisciplinary Research for Energy Efficiency in Production).  The research project introduces a holistic approach to the design and planning of energy efficient production facility; developing an integral simulation for analysis and optimization of energy flows form micro (machine) to macro (production layout, building) level.   Within the project scope, different Building-Information-Modeling-tools have been tested for design of a parametric, digital building-model. The information embedded in this model was transferred in the first step to thermal simulation- and life-cycle costing models. Based of qualitative analysis of potentials and deficits of the practicability, usability and interoperability of BIM-tools within complex collaborative environments, recommendations for producing and processing building information models serving a multitude of purposes will be presented.
