Overheating Analysis and Thermal Modelling

Our homes and places of work are being built more air tight than ever before. This is great for keeping the cold out in winter, but can cause serious heat problems in the summer.

Overheating Analysis - At what stage(s) does this apply during planning?

We are building our homes and places of work more air tight than ever before, using better building materials and improved workmanship. This is great for keeping the cold out in winter, but can cause serious heat problems in the summer.

What is overheating?

Overheating is when a building collects serious levels of heat in the summer and is becoming more of an issue every year. Buildings that are heavily-glazed and positioned in unshaded areas, especially those in urban areas and on the lowest floors of high-rise developments, are most at risk.

Overheating homes can cause health problems for residents who may find it impossible to sleep well. This is likely to result in increased energy usage, fuel bills and CO2 emissions from utilising air conditioning units as a means of combatting the heat.

Our Approach

Some LPAs, especially those in large urban areas, are now asking applicants to carry out modelling analysis to ensure buildings are designed  to avoid uncomfortable heat in summer months. Our specialists can assess the risk of uncomfortable internal temperatures by completing thermal modelling on your development.

What happens next?

Overheating Analysis is best carried out during the early design stages to allow for passive design before cooling systems are added.
