BREEAM Thermographic Surveys
Themographic surveys are now a feature of BREEAM – the world’s foremost environmental assessment method and rating system for buildings. BREEAM sets the standard for best practice in sustainable building design, construction and operation. BREEAM New Construction and BREEAM Domestic Refurbishment programs both recognise the benefit of a thermographic survey by awarding credits for a Level 2 certified thermographer carrying out a suitable thermal survey.
Whether your building inspection is for insulation continuity in Part L2(b) of building regulations, paths of air leakage, insulation checks or under floor heating inspections for either commercial or domestic projects, Ti have a survey to fit your requirements. Our integrity is guaranteed to bring you true results.
BREEAM Thermographic Surveys – How They Work
Infra-red thermographic measurement works on temperature differential. As the internal of a habitable building will have a higher internal temperature than external ambient at least one point over a
24 hour period, it is possible to assess the performance of the insulation. In order to correctly carry out this thermographic assessment, it is necessary to achieve a 10ºC differential between internal
and external ambient. With this, if facing the external of a building envelope, it will be possible to view escaping heat through poorly insulated walls or badly sealed windows as elevated
temperatures. Likewise, if viewing the same envelope internally, these same areas will show up as areas of lower temperature.
Building Thermal Images
Air Leakage Thermal Imaging
Air leaks are common throughout a building envelope and these can lead to higher energy consumption, ventilation and condensation, resulting in a poor indoor climate. To detect air leaks with a thermal-imaging camera, a temperature and pressure difference over the construction is needed.
The air leak itself is invisible but the camera will provide evidence of the characteristic patterns that occur when there is cold air ingress through a structure that causes surfaces to cool down in its path.
Thermal imaging is also suitable for identifying potential sites for condensation build-up, which is important as moisture damage is the most common cause of structural deterioration. Air leakage can cause condensation to form on walls, floors or ceilings and as wet insulation takes a long time to dry it becomes the prime location for mould and fungi.
