Energiesprong: how a Dutch solution could improve Britain’s energy inefficient housing

There’s little doubt that many of Britain’s homes need to improve their energy efficiency. A 2015 study by the Association for the Conservation of Energy found that the UK has among the highest rates of fuel poverty and one of the most energy inefficient housing stocks in Europe. In terms of energy efficiency, the UK housing’s walls came 7th out of the 11 countries analysed, while its roofs were ranked 8th, its floors 10th and its windows 11th.

Badly heated housing has significant impacts on health. In 2011, an analysis by Friends of the Earth highlighted the links between cold housing and poor mental and physical health:

“The main health conditions associated with cold housing are circulatory diseases, respiratory problems and mental ill-health. Other conditions influenced or exacerbated by cold housing include the common flu and cold, as well as arthritis and rheumatisms.”

However, people living in energy inefficient homes are often those least able to afford the necessary retrofits, such as insulation, new boilers and double glazing.

The rise and fall of the Green Deal

In 2013, the coalition government launched the Green Deal, a retrofitting programme that aimed to provide an affordable solution for low-income households struggling to keep their homes warm. However, it soon became clear that the Green Deal was too complicated for the energy efficiency sector to administer, and too hard for householders to understand. After three years of disappointing take-up, the scheme was scrapped in 2015.

With no replacement for the Green Deal on the horizon, agencies supporting fuel-poor households have been trying to fill the gap. The Trussell Trust, for example, has been opening “fuel banks” in towns and cities across the UK, providing vouchers for paying gas and electricity bills.  Important as they are, these initiatives cannot take the place of housing improvements.

An energy leap forward

The demise of the Green Deal left a gap in the UK’s retrofitting market. However, a recent initiative that shares some of the features of the Green Deal has shown early promise as a possible substitute.

The Energiesprong (“energy leap”) model has its origins in the Netherlands. Energiesprong is a network of organisations committed to urban and regional development. It brokered a deal between housing associations and builders to refurbish houses to net zero energy levels. This means the homes do not consume more energy for heating, hot water and electricity than they produce. Householders commit themselves not to use any more energy than an agreed amount. If they do, additional charges apply, but these are likely to be minimal thanks to the improvements in insulation.

So far, the Dutch scheme has proved successful; the first 800 retrofitted homes have performed better than expected, producing more energy than they consume. The tenants are very satisfied with the improvements and Dutch housing associations have committed to upgrade 111,000 homes under a wider roll-out.

Energiesprong in Britain

The Energiesprong concept is now being applied in the UK, where property developers are working with local authorities and social housing providers on prototypes.

Housing associations will finance the up-front costs of the work, including external wall insulation, roofing and renewables. These will be repaid by the energy cost savings resulting from the upgrade. Unlike the Green Deal, however, the Energiesprong concept is more straightforward and easier for consumers to understand, and refurbishments can be carried out within 10 days. In the UK, between 10 and 30 homes have been undergoing improvements in pilot projects during 2016, with a target of 5000 retrofitted homes by 2018.

The concept also has something to offer owner-occupiers; in addition to improving a property’s energy efficiency, Energiesprong also delivers a better-looking exterior. As Energiesprong UK director Arno Schmickler explained to Architects’ Journal:

“We are trying to position a high-quality, desirable product, to make your neighbours jealous – that really works.”

An off-the shelf retrofit?

The Energiesprong process in the UK must overcome significant challenges before it can achieve the levels of success seen in the Netherlands. Although it has secured European Commission funding, Energiesprong UK could achieve a much greater impact with government support. In addition, changes to planning guidance will be required to enable retrofitting without the need for explicit planning permission. The UK retrofitting sector must also make technical and cultural adaptations if it is to emulate the impact of their Dutch counterparts.

But if Energiesprong takes off in the UK, Arno Schmickler foresees the day when retrofitting could become as straightforward as choosing a new sofa:

“We want to position this where you could walk into, dare I say it, Ikea, and buy your Energiesprong solution while you’re kitting out your home with new furniture. ‘That’s how easy it should become.”
