Thermal modelling can take a number of different forms but is usually used as an advanced method of simulating the likelihood of overheating problems within a proposal. For that reason it can sometimes also  be referred to as an Overheating Analysis.

As average temperatures are set to rise, and buildings are built increasingly airtight and well insulated, overheating has become a more common problem for designers and the future occupants. This in turn raises the likelihood of air-conditioning systems being installed, impacting on the environmental performance of the development.

Buildings with lots of southerly glazing, within urban areas and those on the lower floors of high-rise buildings are most at risk.

To mitigate this risk, the thermal performance can be simulated using complex software which considers both passive and active measures to reducing overheating risk, airflow and solar and incidental gains (those from the occupants themselves and their appliances).

Many Local Authorities will now request such a study if they consider there is a risk of overheating, often using the London Plan Cooling Hierarchy as a basis for assessment. In June 2022, The new Building Regulations Part O came into force and full assessments of overheating are now required for many new housing schemes. Contact us for more details!

T16 Design have undertaken many such studies and can assess even the most complex schemes. We can usually offer a "package" quotation with our other services to save you cost and the need to employ multiple consultants.
