BSRIA topic guide on mould in buildings TG 26/2024
Mould and dampness constitute an issue that affects millions of buildings every year. This BSRIA topic guide gives an overview of how mould occurs in buildings, how it can be diagnosed and what mitigation strategies can be put in place.
Mould and dampness constitute an issue that affects millions of buildings every year. Dampness refers to signs of water damage on building materials due to excess moisture in the air or within the materials. On the other hand, moulds are living microorganisms that grow on surfaces forming darker spots and can move through the air.
This BSRIA topic guide includes sections on:
- Determinants of mould in a building context
- Mould diagnostics
- Mould mitigation strategies
It is published in partnership with the UK Centre for Moisture in Buildings (UKCMB) and UCL Department of Civil, Environmental and Geomatic Engineering (CEGE).
The guide is available to download here.
BSRIA, in conjunction with UKCMB and UCL-CEGE will be delivering a webinar on mould in buildings on 5th February 2025 13:00-14:00. For more information including registration, click here.
