KS16: How to Manage Overheating in Buildings

A practical guide to improving summertime comfort in buildings

This publication provides a practical introduction to the subject of overheating for building owners, managers and users. It explains why overheating may be ‘uncomfortable' and what factors can cause overheating in offices and other buildings. It also gives guidance on how to minimise the risk of overheating in existing buildings and provides information on practical measures that can be applied including those that provide occupants with the opportunity to reduce individual discomfort.

The guidance in this publication is aimed primarily at non air-conditioned office buildings, although parts of it could also be applied to air-conditioned offices. Much of the guidance can be applied to other building types with similar occupancy patterns, such as schools and retail buildings. It is also applicable to dwellings.

Note: The tool to provide information about daily local running mean temperatures, as described on page 12 of KS16, is currently under development, but will be made freely available when testing is complete (note added August 2013)
