Temperatures could soar to dangerously high levels in some homes insulated under the government's flagship Green Deal scheme, experts have warned. Energy-saving measures designed to save on winter fuel bills and protect the environment could pose a risk to health during summer heatwaves, they add. Homes in densely populated urban areas such as London are most at risk. The government says it is aware of the problem and is taking steps to prevent overheating in Green Deal properties.

Heat can build up during the day and has nowhere to escape at night leading to poor air quality and a greater risk of heat stress for the occupants which, in extreme cases, can kill. It is vital that homes in the UK are better insulated to help meet carbon emission targets and save on winter fuel bills. But the risk of overheating had been overlooked in the "big rush to insulate and make homes airtight", particularly as more extreme weather events, including heatwaves, are being predicted for the UK by meteorologists.

"Overheating is like the little boy at the back of the class waving his hand. It is forgotten about because the other challenges are so big," he told the BBC News website. Very effective measures are being taken to protect against winter temperatures but by doing that they increase the risk of overheating during summer.

Research by Leicester De Montfort University, suggests top floor flats in 1960s tower blocks, and modern detached houses were most at risk, particularly if they were south facing. Heat was likely to have the biggest impact on elderly or infirm people who remained at home all day, the research suggests. The elderly are going to suffer. Suffering means they are going to die from overheating.

Under the Green Deal, householders take out loans to finance improvements such as double-glazing, loft insulation or more efficient boilers. The idea is that the energy savings they make should more than compensate for the repayments. In total it said there had been 38,259 Green Deal assessments, where customers are given initial advice about what energy improvements they might be eligible for. Of those, 241 households have confirmed they would like to proceed with work.

According to research by a group of leading engineering and climate change experts, published last year, "Green Deal measures could create new problems in the future, with inappropriately insulated properties experiencing poor indoor air quality and significant summer overheating. It said the increased likelihood of summer heatwaves could lead to rise in heat-related deaths from 2,000 to 5,000 per year by 2080 "if action was not taken".

The Department for Energy and Climate Change says it has now issued fresh guidance to Green Deal suppliers to help reduce potential risk from installing energy efficiency measures.

He said there were simple measures anyone could take - whether living in a well-insulated home or not - to keep heat levels down, such as keeping windows closed during the day to trap cool air and opening them at night. Fitting shutters to windows and painting exterior walls white - both common sights in Mediterranean countries - would also help, but were unlikely to be widely adopted in the UK due to the relative rarity of heatwaves.

With the weather constantly on the up at the moment it seems like Britain may be able to enjoy a proper summer for once. However industry experts have warned that homes insulated under the Green Deal scheme could be facing dangerously high temperatures both over the coming months and future summer times. 

Prof Chris Goodier, of Loughborough University’s department of civil and building engineering, told the BBC that the risk of overheating had been overlooked in the “big rush to insulate and make homes airtight”. He cited homes in urban areas are most at risk from problems during summer heatwaves. 

"Overheating is like the little boy at the back of the class waving his hand," he said. "It is forgotten about because the other challenges are so big."

"If you are in the wrong type of house, facing the wrong way, in the wrong street and you don’t deal with heat in the right way, it is a problem. Particularly for the elderly. They are going to suffer. Suffering means they are going to die from overheating."

His team's report suggested that with the increased likelihood of summer heatwaves in the future, there could be a rise in heat-related deaths from 2,000 to 5,000 per year by 2080 if action was not taken. To combat this, the DECC are now issuing fresh guidance to Green Deal suppliers to help reduce this risk while continuing to install energy efficient measures.

In a statement they said: "If energy efficiency measures are installed appropriately, overheating should not be a common problem and there’s guidance available for those involved in the Green Deal."

“The DECC is working with experts and other government departments to understand the potential risk of overheating in retrofitted homes and ensure that the energy efficiency supply chain, including those working within the Green Deal, are aware and guidance is provided on homes which are most likely to be vulnerable and what steps could be taken to minimise any risk of overheating."

The Department of Energy and Climate Change have released the first quarterly Green Deal statistics, which have been met to mixed response by leading industry professionals. These statistics show that almost 40,000 people so far have had an assessment carried out.

The key figures for up to the 16th June are:

• 38,259 homes have had a Green Deal assessment
• A rise in assessments every month: 7,491 in March, 9,522 in April, 12,146 in May
• 241 customers have obtained a quote from a Green Deal Provider and have confirmed they wish to make energy efficient improvements to their home
• Four customers have signed up to a Green Deal Plan and progress is being made to install energy efficient measures
• 961 people have claimed cashback for a new boiler installation – 902 gas and 59 oil boilers
• 1,254 installer organisations are accredited and qualified to work within the Green Deal.

On the other side of the argument, HHIC (Heating & Hotwater Industry Council) Director Roger Webb considered the figures "very disappointing". He went on to say: "However, on a positive note, they will be a wake-up call for the government to simplify the scheme and to really engage with the small installer. It is not too late for the Green Deal as the scheme has hardly got off the ground and further action will be required to reform the scheme. The heating industry from the success of the cashback incentive want to stress that figures prove that changing a boiler is one of the key routes to gain consumer interest in the Green Deal and enabling further measures to be taken up."

Meanwhile, earlier last week it was revealed that a cross-section of industry leaders had written to all three main political parties in an attempt to persuade them to come together to ensure that the Green Deal doesn't fail. The letter was addressed to energy secretary Ed Davey (Liberal Democrat), minister Greg Barker (Conservative) and shadow energy minister Luciana Berger (Labour) can be viewed in its entirety below;

-----

We are taking the unusual step of writing the same letter to all three of the main political parties, setting out our major concerns with current retrofit policy and our belief that we can only address this most urgent of challenges with a greater degree of cross party consensus, and collaboration between government and industry.

Government’s own figures show that meeting our legally binding carbon targets requires a high level of retrofit across the UK’s 26 million domestic properties, at an average of one home per minute between now and 2050. Clearly this is a monumental task, but it also represents a tremendous opportunity: to reduce energy bills, improve health, provide jobs in the construction sector, and avoid additional costs of new generating capacity.

However, to have any chance of successfully tackling this, it will require government – either this one, or indeed any future one – to address the following major issues:

Green Deal interest rates: The current rate of interest for Green Deal finance is in danger of acting as a major disincentive to take up, as well as minimising the extent of the measures available in a Green Deal package. Taking inspiration from the effect of recent government intervention to support new build homes, government should explore, with stakeholders, what options are available to reduce risk associated with providing Green Deal finance – even if this means greater intervention in the market.

Long term structural incentives: Even if Green Deal was available at a much lower cost of finance, long term structural incentives would still be needed to ensure sufficient uptake. Council tax or stamp duty could be used to send a signal to consumers and the market on the direction of travel, and both could be applied in a fiscally neutral way to HMT. Regulation could also be used, in particular Consequential Improvements, which government itself has estimated would lead to an additional 2.2 million Green Deals being taken up.

Stakeholder engagement: There needs to be a better on-going dialogue between government and those trying to deliver the Green Deal on the ground, in order to overcome obstacles, reduce unnecessary complexity, identify future issues and learn lessons. At the very least this should take place through a high level industry advisory board co-chaired by a minister and a senior industry figure. It could also involve a more operational body, or ‘hub’, which government has previously expressed support for.

Long-term certainty and political consensus: There is an increasing sense that the Green Deal, and indeed energy bills more generally, are being used as a political football, which is not good for confidence in the market. These challenges will affect any party, or parties, of government and very bold decisions will be required. We believe there needs to be a new consensus forged between the main parties around retrofit, to depoliticise what is ultimately a long-term challenge that it is in the nation’s interest to successfully address.

New research from the Department of Energy and Climate Change (DECC) has revealed that taking energy saving measures on your home (via the Green Deal or otherwise) could see a significant rise in its value.

The report took into account over 300,000 property sales in England between 1995 and 2011, making it the most comprehensive research in this area to date. The results found that on average house value could be increased by up to 14%, with that figure even reaching 38% in certain parts of the country.

For an average home in England, improving its EPC (Energy Performance Certificate) from band G to E, or from band D to B, could mean adding more than £16,000 to the sale price of the property. In the North East, improved energy efficiency from band G to E could increase this value by over £25,000 and the average home in the North West could see £23,000 added to its value.

Energy and Climate Change Minister Greg Barker said: “We have long known the benefits of making energy saving improvements to the home, but this study is real evidence of the huge potential rewards. Not only can energy efficient improvements help protect you against rising energy prices, but they can also add real value to your property. This Coalition is committed to helping hardworking families with the cost of living. The Green Deal is designed to do exactly that.

“The Green Deal is helping more people make these types of home improvements, reducing high upfront costs and letting people pay for some the cost through the savings on their bills. The Green Deal is a great option for anyone wanting to improve the look, feel and potentially the value of their home.”

If you're reading this as an installer, it illustrates yet another reason why so many people are turning toward renewable energy sources - especially while the Green Deal is assisting in the cost. Training in renewable energy methods is the perfect way of expanding your business as well as getting the satisfaction that you are doing your part to help decrease Britain's carbon footprint.

The Green Deal is in danger of “sleepwalking into obscurity”, warns the ECA.

In response to the Energy and Climate Change Committee’s report into the Green Deal, the ECA has said that the findings should be a stark warning for the Government.

The ECA said, “The Energy and Climate Change Committee’s report into the Green Deal issued on 22nd May is a wake-up call to Government, which must keep on top of Green Deal performance if it is to prevent its flagship policy from sleepwalking into obscurity.”

Now the Green Deal is live, the Government must be quick to react to what is happening on the ground, and make changes if success is in doubt. Considering the PV FITs fiasco was worsened by the Department of Energy & Climate Change (DECC) relying on outdated figures on solar installations, the DECC should be accessing real-time information on the Green Deal, right now.

Millions of homes and businesses could benefit from the Green Deal, but at the current rate of assessments it will take around 100 years to get round to them. The first figures on actual Green Deal installation work, which come out in June, will be crucial.

Depending on what these figures say, the DECC may need to be ready with a Plan B. That should include reducing interest rates, which are widely seen as uncompetitive. Even simple measures like making the early adopter loans more obvious to consumers could help.

Awareness of the Green Deal financial incentives is very sketchy; publicity of what people need to do to benefit from the scheme is non-existent. How can the ‘common man’ (or woman) take advantage of the scheme when they are not being provided with any information?

The government call this a "Flagship incentive" - I would call it propaganda.
