Understanding Overheating Guide

The NHBC Foundation has published a guide for house builders, designers and renovators which could be invaluable as global warming means rising temperatures for UK homeowners.

Understanding overheating – where to start has sections on all the key factors in potential overheating – the urban heat island effect, orientation, building design, thermal mass, service design, restricted ventilation, and occupant behaviour. It is complemented by 7 case studies.

‘The last serious heat wave in Europe was in 2003, well before the improvements to the external envelope and airtightness brought about by changes to the Building Regulations in 2006 and 2010.  We do not really know how houses built to these standards will perform, either in the next hot summer or over time with the effects of climate change.’
