Building Information Modelling (BIM) as emerging technology, bearing promise to reduce the fragmentation of the architecture, engineering and construction (AEC) industry, is thereby enhancing integration and enabling life cycle management of buildings. The BIM model serves as a joint knowledge database for the interdisciplinary planning team, involving designers, structural and HVAC engineers, facility managers and other; where data transfer between various models as well as non-CAD tools and simulation software is possible. Thereby BIM bears largely still unexplored potentials to significantly improve over-all energy and resources efficiency of buildings along the life-cycle.

Particularly beneficial is adoption of BIM for design, planning, optimization and management of industrial facilities, where multiple layers of interacting complex systems (building, HVAC and machine floor layout) need careful modelling and management in terms of collisions, change management and multiple adaptions due to the short product-life cycles.

Industrial buildings consume much more energy than other building typologies - the need for powerful modelling, prediction and optimization tools for identification of synergies between the building hull, HVAC systems and production systems is urgent.

This paper explores the potentials and deficits in the current practice of BIM use in the design and analysis and optimization of energy-efficient industrial buildings through case study research of two industrial facilities. So called BIM to BEM approach is thereby applied. As identified problems the varying needs concerning the Level of Detail (detailing of the building model, also known as Level of Geometry) and semantical differences in the modelling procedures of part-taking disciplines (architecture, structural engineering or simulation) were identified; as well as time pressure as one of the main reasons for defects of building models. In order to improve BIM to BEM not only interoperability issues of the software has to be improved, but moreover, the redefinition of the design process and enhancement of individual capabilities is necessary.
