UK: Experts have warned that the UK's Green Deal scheme to promote higher levels of insulation in buildings could inadvertently generate potentially lethal overheating in some residences.
Researchers from Loughborough University and the University of Reading have highlighted that Green Deal-inspired changes may be unsuitable for top-floor flats (especially in 1960s constructions) and modern detached houses. In both cases, southerly aspects could add even more to summer temperatures, creating potentially unbearable conditions for occupants.
Speaking to the BBC's website, Professor Chris Goodier of Loughborough University said that it was 'vital' that the UK improved insulation in its housing stock for the sake of lower fuel costs and carbon emissions, but said that the 'big rush to insulation and make homes airtight' risked overheating.
"Overheating is like the little boy at the back of the class waving his hand," he told the BBC website. "It is forgotten about because the other challenges are so big."
Goodier, along with Professor Li Shao of the University of Reading, said that the elderly were among the most at risk of overheating effects as they are more likely to remain indoors during the day and are more susceptible to the effects of extreme temperatures.
The Department for Energy and Climate has now said that it has issued new guidelines regarding overheating to its Green Deal partners in the insulation industry.
The Green Deal has come in for much criticism in the UK since it launch at the start of 2013. The scheme targets the insulation of 14 million homes by 2020 but so far only 38,259 assessments have been carried out. Of these, only 241 homes have committed to proceeding with the installation of insulation.
