Making the case for reducing ventilation requirements through selection of low-emission materials

This paper investigates the feasibility of reducing the outdoor air ventilation requirements by selectinglow-emission materials, while still maintaining acceptable IAQ, for a residential building. The method used was to apply tools such as a computerized database of material emissions and its accompanying IAQ simulation model (MEDB-IAQ).A real two-storey R-2000 house was chosen as the simulation reference case to serve as the basis for comparisons with alternative material selections.
