Overheating Assessments 


We provide overheating assessments for all types of buildings, which help to ensure buildings are designed to prevent overheating and minimise the use of mechanical cooling. An overheating assessment uses a dynamic thermal model to analyse the temperature reached in a building over summer and assess if the rooms overheats, according to a set of defined criteria. Buildings can also be assessed against overheating criteria in predicted future climate change scenarios, up until 2080.


Overheating assessments are often required for planning permission. All major developments within London are required to demonstrate how they have reduced overheating and air conditioning use as part of London Plan Policy 5.9. Greater London Authority referred schemes also require an overheating assessment.
