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.
Top Tips for Overheating Analysis and Thermal Modelling
Overheating Analysis is best carried out during the early design stages to allow for passive design before cooling systems are added.
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.
The London boroughs are leading the way when it comes to checking new builds for overheating. The London Plan sets out a Cooling Hierarchy which encourages developers to design buildings to reduce internal temperatures, and to only use air conditioning as a final option.
The Energist Approach
Our specialists can assess the risk of uncomfortable internal temperatures by completing thermal modelling on your development.
