CIBSE has released a webinar on testing for air leakage – the uncontrolled movement of air through a building envelope or component due to the porosity of building fabric materials, interfaces between materials and components and imperfections in the construction of the building.
TM23 Testing buildings for air leakage (2022) addresses testing non-domestic buildings and dwellings. It describes the two main test methods: fan pressurisation and low-pressure pulse. It intends to provide the methodology principles and framework for regulatory compliance purposes.
