Mitigating Residential Overheating in the UK

Residential overheating has become a critical concern in the UK, driven by climate change, urbanisation, and increasingly airtight building designs aimed at energy efficiency. The Chartered Institute of Building Services Engineers (CIBSE) defines overheating as "when the internal temperature threshold of 26ºC is surpassed for over 3% of the time". Exceeding this threshold can significantly affect occupant thermal comfort, health, productivity, and overall well-being.
