Abstract: The article analyzes the impact of measured concentrations of Total Volatile Organic Compounds (TVOC) emissions determined for four BREEAM certified buildings on the Indoor Air Quality Index (IAQ index ) and the overall Indoor Environment Quality index (IEQ index ). The IEQ index indicates the percentage of building users who are satisfied from the indoor environment. In existing IEQ models, currently the concentration of CO 2 is mostly used to evaluate the IAQ index sub-component. Authors point out that it is recommended to use TVOC instead CO 2 at pre-occupant stage where building is mainly polluted by emission from finishing products. The research provides the approach where the component related to the emission of TVOCs is implemented to IEQ model. The first stage of assessment was a test of the volatile organic compounds concentrations in case study buildings. Secondly, the analysis results were assigned into the number of dissatisfied users (PD( IAQ) ) from the theoretical function given by Jokl-Fanger resulting from the Weber-Fechner equation. Finally, the overall IEQ index was calculated. The IEQ approach proposed in this paper is mainly based on a consideration of EN 15251 and scientifically accepted models.
