Risk of overheating in buildings
‘Overheating in Homes: Keeping a growing population cool in summer’, published in October 2015 recommends that new measures are introduced, overhauling the building regulations, in order to tackle a problem that, as cities become hotter in the future, only looks set to worsen.
The report has built upon a ComRes survey commissioned by WSP PB published the previous month. The survey found that four out of five (83%) of Londoners suffered from overheating in their home on at least one occasion during this year’s summer. The survey also found that almost a third (31%) of those who suffered from overheating at night felt tired or unwell the following day.
Overheating has become an emerging issue due to factors including climate change, susceptibility to heat amongst an ageing population, insulation, air-tight construction, and the ‘urban heat island’ effect where metropolitan areas experience warmer temperatures than surrounding rural areas. Government figures show that around 2,000 deaths a year are attributable to heat.
According to the report, there is ‘overwhelming agreement’ that the Standard Assessment Procedure (SAP) is ‘inadequate’ at measuring the risk of overheating. The following steps are proposed to try and tackle the issue of overheating:
- A new, robust regulatory overheating analysis method for all new developments.
- Requirement for new housing developments to adhere to a ‘cooling hierarchy’ to assess the most relevant measure to combat overheating.
- Requirement for new buildings to be designed to facilitate retrofitted cooling installations.
- The introduction of measures on a development and city-wide basis for reducing the urban heat island effect, including green infrastructure and ‘cool pavements’.
- Measures to move towards an ‘all-electric city’ that will lead to a reduction in heat production from all vehicles and buildings in urban areas and will also reduce noise pollution, enabling people to open windows and so benefit from natural ventilation.
Author of the report Barny Evans, associate at WSP | Parsons Brinckerhoff, said: “Even as winter approaches overheating needs direct action. Current regulations rightly focus on stopping us feeling the cold, but we have yet to find the right solution to uncomfortably hot homes.
"This represents an opportunity to build better, more sustainable and ultimately more desirable homes. An increase in population and densification of our cities means we are more likely to live in flats in future, so we need to understand how to build these homes so that they are comfortable for residents now and in the future.”
Responding to the report, Association for the Conservation of Energy director Joanne Wade said: “Overheating isn’t a main issue now but will be increasingly important with climate change. The key thing is ventilation as well as insulation. We need to improve the quality of our building stock by making it properly insulated and properly ventilated.”
