We present an approach for holistic indoor environmental quality (IEQ) assessment in corporating dynamic heat and moisture transport effects, indoor air flow and pollutant distribution. A common tool infrastructure provides interfaces to multidisciplinary models that are using product and material specific data stored in Building Information Models (BIM) for early design assessment. Hence, we present the results of a prototype tool development utilising integrated dynamic simulation models on the basis of the Modelica language. The sub-domain models for airflow and hygrothermal BPS are cross validated with state-of-the-art tools and experimental results. The properties of innovative multi-functional eco-materials and components are provided in a structured database to provide high quality predictions of IEQ under a broad range of boundary conditions and implementations. In an integrated design process (IDP) the procedures for simulations and results evaluation are automated and comparable figures for overall IEQ ratings are provided by a user friendly front-end.
