What is Condensation Risk?
A disadvantage to building homes to such a high level of air tightness is they are more prone to internal condensation and mould growth.
Building regulations aim to ‘adequately protect’ buildings from both interstitial and surface condensation. Surface condensation can occur where reduced levels of insulation create a cold point on a particular wall, roof or floor. Interstitial condensation can occur where vapour can build up within a construction with no means of escaping.
When is Condensation Risk Analysis required?
If you are working to a bespoke construction, or are constructing a basement, your design will more likely to need additional checks to ensure condensation isn’t going to be a problem.
These calculations are often completed as part of the detailed design to ensure the proposed building junctions and construction are designed to limit the risk of condensation forming.
The Energist Approach
Our assessment teams can assess both types of condensation analysis, and can create calculations for designs and constructions of all types.
Condensation analysis is closely linked to thermal bridging analysis and U-Values – these services are also available from Energist.
