Thermal model sampling

Thermal modelling, in accordance with CIBSE AM11, does not need to be carried out for each individual home, where the thermal modeller uses their professional judgement to ensure that an appropriate sampling approach is adopted, in line with section 3.1 of CIBSE TM59 and the following considerations:

  • All house types are adequately sampled
  • The homes and situations most at risk of overheating are modelled (i.e. the worst case scenarios)
  • There is no risk of overheating in the homes not modelled

The modeller needs to provide evidence and justifications that demonstrate how the samples have been determined, with their justifications, in line with the above.

A house type should include homes that are identical in specification, design and location (end/ mid-terrace, ground or mid/ top floor).
