Outdoor Air Pollution

Air pollution is one of the most important environmental risks to human health, and it is perceived as the second biggest environmental concern for Europeans after climate change. It has been estimated that 90% of population worldwide are breathing highly polluted air. The indoor and ambient air pollution are recognised as one of the risk factors for non-communicable diseases. Buildings both affect the quality of the outside air (pollutant emission) and the purity of the indoor air (air filtration).

X-tendo elaborates and tests a methodology for reporting on the buildings’ contribution to air pollution as well as the air-filtration efficiency in ventilation systems. The methodology for estimating the Local Air Pollution Contributor Index is based on comparisons between pollutant emissions values from assessed buildings and from reference ones. In the methodology for determining the Indoor Air Purity Index, the actual quality of external air and efficiency of air filtration system is taken into account.
