Like the structure of the building, the building envelope accounts for 20% of the total building cost, A holistic approach to performance evaluation will not only ensure that the numerous criteria of the building envelope, such as structural, thermal, moisture, acoustics, etc. are all satisfied, but also ensure that good integration is established between the envelope and the structure as well as with the ventilation system of the building. This multi-disciplinary performance checking can greatly benefit from the new developments in Information Technology (IT) and Industry Foundation Classes (IFC) from the International Alliance for Interoperability (IAI) for the building industry. This paper describes the development of a computer tool or framework which includes a preprocessor, an application integrator, and a postprocessor. The framework extracts the basic geometric data of a house from CAD drawings based on an IFC data model, links to performance evaluation applications such as MOIST3.0 and HOT2000, and compares evaluation results with a set of criteria.
