ABSTRACT

Introduction Over the last 30 years two interrelated themes have become of increasing interest to those designing, commissioning and, indeed, using buildings: the need for energy efficiency and the provision of adequate indoor air quality. Both are intrinsically linked together via the ventilation regime of the building. The energy used to supply and condition fresh air to a building can be a significant contribution to the carbon footprint of a building, while the resultant ventilation rate along with the strength of pollutant sources will determine the level of indoor air quality (IAQ).
