Under the latest edition of the BREEAM Technical Manual (SD5076) it is possible to be awarded a BREEAM credit by conducting a thermal imaging survey of the building fabric. The thermographic survey is required to be completed in accordance with MAN 04 Commissioning and handover compliance notes CN3.3 and CN3.4 by a UKTA Approved Level 2 thermographic surveyor. The thermographic survey is required to confirm:
- Continuity of insulation in accordance with the construction drawings
- Avoidance of excessive thermal bridging
- Avoidance of air leakage paths through the fabric (except through intentional openings)
- Any defects identified via the post construction inspection are required to be rectified
To achieve compliance with BRREAM the principal contractor needs to account for a thermographic survey within the project budget and programme of works. Once construction is complete, a thermographic survey of the building fabric is to be undertaken in accordance with the appropriate standard and by a professional holding a valid Category/Level 2 certificate in thermography.
