The effect of ventilation on volatile organic compounds produced by new furnishings in residential buildings

It can be difficult to tease apart the sources of the many chemical substances that can adversely affect indoor air quality (IAQ). These can be generated from primary sources, e.g. cleaning products, fragrances and wall decorations, and created in-situ (secondary emissions). Inputs due to human activities (heating, smoking, etc.) add to the catalogue of chemical possibilities. This study examines the effect of airtightness and ventilation on volatile organic compounds (VOC) concentration in newly-furnished unoccupied residential houses. Further objectives included investigating the effects of airtightness and mechanical ventilation on internal VOC concentrations in two rooms with controlled simulated occupancy.
