A thermal comfort model, or overheating assessment, is carried out on a development to ensure the indoor environment does not exceed a comfortable limit for the occupants. 

Thermal models must confirm that the design of the building is in line with CIBSE Guide A and CIBSE TM:52 or with CIBSE TM:59 for residential developments. 

Do I need a Thermal Model?

If your building is at risk of overheating, then a thermal model is an effective way to provide reassurance that the indoor environment will be comfortable for the occupants. Many local councils now require an overheating assessment to be carried out for major developments to ensure the health and wellbeing of the building users, and also to guard against the risks of overheating from future climate change. The GLA London Plan similarly aims to protect building users from risks of future temperature rises due to climate change.

BREEAM assessments have long required thermal comfort modelling to gain Health and Wellbeing (HEA) credits, and continue to do so in the new BREEAM 2018. 

Thermal modelling can also be a very effective tool in the value engineering of large developments. Knowing that the comfort of the building’s occupants is secured with a certain design specification allows for more cost-effective measures to be considered in other areas of the project.
