Overheating

Ever increasing winter energy efficiency measures and external temperatures as a result of intense urbanisation and climate change will increase the risk of overheating in buildings especially in homes that primarily depend on passive measures to achieve year round internal comfort. CIBSE believes that occupant comfort, health and wellbeing should be carefully considered in the design of buildings and recommends a holistic approach to performance analysis where internal thermal comfort is investigated throughout the year.
