BSRIA Indoor Air Quality TG 12/2021
|
Air of good quality is air in which there are no known contaminants at harmful concentrations. Air pollution can have a negative impact on our health; from short-term effects such as eye irritation and coughs to long-term effects such as respiratory infections and cancer. The effect on health depends on the contaminant concentration and exposure time.
This topic guide - which replaces TG 12/2016 - gives a brief introduction to the subject of indoor air quality (IAQ). It describes the importance of IAQ, its effects on health, the most common contaminants and their exposure limits, how to measure them, the role of ventilation and the law. It is aimed at facilities managers, building owners, building occupiers and anyone else who needs a basic understanding of the topic.
The guide is free to download.
