We present an approach for holistic indoor environmental quality (IEQ) assessment incorporating 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 simulations 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 as basis for high quality predictions of IEQ under a defined range of boundary conditions. The procedures for simulations and results evaluation are automated and comparable figures for overall IEQ ratings are provided by a user friendly interface. The main components of the IEQ Assessment Tool are the 3-D graphical user interface, the dynamic multi-physics simulation model, and the tabular and graphical interpretation of the simulation results in terms of hygrothermal, acoustic and air quality performance.
