The UK’s 2017 Climate Change Risk Assessment (CCRA) highlighted overheating as a significant risk to our health and comfort, with heatwaves expected to occur in most summers by the 2050s. Maintaining a comfortable indoor temperature is vital to both well-being and productivity, with the location, fabric, orientation & use of a building all factors that can contribute to the risk of overheating. At TEDS we have extensive experience of designing to avoid the threat of overheating and where appropriate use dynamic thermal models to test the resilience of proposals.
