eeBIM Lab – towards a coherent green building design process

Abstract: One of the major challenges in building design and maintenance today is the use of Building Information Modeling (BIM) for simultaneously optimising energy performance and lifecycle costs. This requires a structured approach that enables continuous changes in design variables and assessment on energy consumption. However, while simulation and analysis tools are abundant within the participating domains, insufficient software interoperability and lack of standardisation, with subsequent loss of information and knowledge in information exchanges between disciplines and lifecycle phases, are characteristic gaps in the planning processes reducing the efficiency of the design solutions. This paper presents a a general procedure of the new concept of a BIM-based Virtual Laboratory for the design and maintenance of energy-efficient buildings (eeBIM Lab); shows the main results that already worked out and outlines the principal approaches for further implementations. In the first part, a new design methodology based on verifiable Key Indicators is introduced It enables optimal use of the eeBIM Lab by supporting the decision making across the participating domains in green building design. In the second part, the main steps of the procedure are described: (1) the Project setup, (2) the design and (3) simulation/ analaysis cycles and (4) the use of BIM for high level decision support. Furthermore, the related key methods and tools are described in short for their further implementation.
