Both guides offer information to help avoid uncomfortable conditions for occupants. These support the existing publication ‘KS16: How to manage overheating in buildings' which gives guidance for building managers and owners about the causes of overheating and how to mitigate it. CIBSE also provides guidance for building managers and occupants in the form of top tips on how to manage overheating, available to download from the CIBSE website.
Fergus Nicol, lead author of the Guide TM52 commented: "Overheating has become a major problem in building design. The rising cost of energy combined with global climate change has reduced the options available for building comfortable, low-energy buildings. Research has been directed towards methods for increasing indoor winter temperatures but this can lead to lightweight, highly insulated buildings that respond poorly in the summer. To assess this further, CIBSE responded by forming the Overheating Task Force."
The CIBSE Overheating Task Force explored what is needed from building designers, service systems, ventilation and facilities management in order to maintain comfortable living and working conditions, especially in the summer months. Occupant comfort is particularly important as it directly impacts productivity and health which in turn affects employers. Only recently it was quoted that Mark Zuckerburg, founder, Facebook, keeps his offices at 15°C as it is believed to increase productivity. CIBSE's recommended temperature is 20°C.
CIBSE President George Adams also emphasised the importance of designing buildings fit for a changing climate due to global warming in his inauguration speech entitled ‘Whole Life Thinking'. The subject was also discussed further at the CIBSE Natural Ventilation Group event, Passive Building Technology in Practice, 21st June at UCL.
