E=0: Desirable, warm, affordable homes for life

Discover the E=0 pilots in France

The EnergieSprong approach was launched in France in March 2016, by GreenFlex, a firm specialised in helping organisations accelerate their social and environmental transition. GreenFlex has set up a market development team of 7 people to adapt and implement the EnergieSprong approach in France, and works with local stakeholders to do so.

Within the E=0 project, they are working side by side with the housing associations ICF Habitat and Vilogia, who are experimenting the first EnergieSprong refurbishments in France.  Vilogia is renovating 10 houses with a consortium led by Rabot Dutilleul Construction, and ICF Habitat is renovating 12 houses with a consortium led by Bouygues. Both projects will be finished by the summer 2018 and will provide precious feedback for the further deployment of EnergieSprong in France.  

Those first demonstrators have inspired others: Many housing associations, solution providers and facilitators have shown interest in the project and become regular attendees of workshops and members of the steering committee. 36 of them, among which 9 housing associations, have signed a charter engaging them to contribute to the EnergieSprong dynamics in France, and two new projects have already been launched (by Neotoa and Est Metropole Habitat).

Project manager: Vilogia, a social housing association: http://www.vilogia.fr/

Consortium: Rabot Dutilleul Construction, Pouchain, Symoé, Smart Module Concept, Redcat Architecture, Nortec

Planning: The works started in January 2018 and ended mid-June 2018.

The project: 10 houses have been renovated to reach an energy E=0 level with a performance guarantee of 25 years. They are typical northern brick houses with two floors and four rooms built in 1952, with an initial energy performance of E. The refurbishment included the insulation of the houses through new prefabricated facades and roofs. A heat pump is now providing hot water efficiently, and solar panels have been installed to provide energy. An energy module has been integrated in the façade and gathers heat, hot water, ventilation and cooling systems to make the maintenance easier. Tenants can also enjoy new refurbished kitchen and bathroom, and will soon have access to a monitoring device to follow their energy consumption. In the following months, they will benefit from coaching to help them understand and master their energy consumption.

Discover E=0 in the UK 

Energiesprong UK (hosted by NEF) is leading on the effort to bring the Energiesprong concept to the UK. The E=0 project is supporting UK housing associations who are pioneering Energiesprong retrofits by working on demonstrators for the net zero energy renovations.

Energiesprong UK has 14 founding partners: frontrunners in the field of sustainability and innovation from the social housing sector as well as construction companies that share the vision of working together to provide desirable warm affordable homes for life. In addition, it has a range of supporting partners that are collaborating in the transformation Energiesprong UK is working to achieve. 

Two E=0 pilots are underway in the UK. In Maldon, Essex, fives homes are being retrofitted by solution provider ENGIE on behalf of housing association Moat Homes. In Nottingham, 17 homes are being retrofitted by solution provider Melius Homes on behalf of owner Nottingham City Homes. Both projects are due to complete around summer 2019.

E=0 demonstrator in Maldon (UK) 

Moat is a leading housing association working in the South East of England, providing high quality homes and services.

Moat shortlisted 10 homes in Maldon that would benefit from the energy efficiency works that Energiesprong can offer. Works proceeded on 5 of these. Moat are excited to be part of the groundbreaking project and recognise the long term advantages that Energiesprong could bring to some of their customers.

Moat procured ENGIE as their solution provider. Works are underway and are expected to be completed for Summer 2019

E=0 demonstrator in Nottingham (UK)

The new Nottingham Energiesprong pilot will radically improve 17 homes, comprising of 10 bungalows and 7 two-bedroom, three-storey houses. The properties, owned by Nottingham City Homes, are on West Walk, adjacent to the first multi award-winning pilot.

Work began on site in December 2018 to rollout the piloted solution. Plans for the rollout include clusters of homes with communal energy centres with ground source heat pumps fed by electricity generated from solar panels on the roofs. Battery and thermal storage will help make the most of solar energy captured onsite.

Discover E=0 in Luxembourg

In Luxembourg, Neobuild is working with the Fonds du Logement, the biggest housing association in the country, to refurbish an apartment building of 24 units using the Energiesprong method. If the project goes according to plan, the Fonds du Logement and other housing associations could be interested in applying the Energiesprong method elsewhere in Luxembourg. Local construction companies and suppliers are following closely the advancement of the pilot.

The Fonds du Logement has selected an apartment building for the E=0 retrofit. It's located in the City of Luxembourg.

Works are planned to start there in 2018. 

Discover E=0 in the Netherlands

In the Netherlands the E=0 project focuses on two things: a solid financial solution for homeowner associations wanting to achieve Net Zero Energy refurbishments and the set up of the incubator Factory Zero, that develops and produces smart Net Zero Energy (NZE) systems.

A driving focus of this project is for homeowner associations to find a solid financial construction for NZE refurbishments with a duration of 25 to 30 years. Under the E=0 project, we work together with large banks, financial organisations, local governments, provinces and national government to start pilots. By learning in practice, such pilots enable us to generate financial solutions that satisfy all parties involved. All experience and knowledge gained is then translated into tools and manuals for other homeowner associations. You can read more about these pilots in the article “Dutch local governments stimulate NZE for 15 homeowner associations”.

The other main focus of the NWE interreg project E=0 has been to create the start-up and incubator Factory Zero. Factory Zero works in close cooperation with innovative players in the building supply industry to develop, produce and deliver smart, complete Net Zero Energy systems. Industrial scale solutions, innovation and smart thinking are necessary to get the costs for Net Zero Energy refurbishments down whilst bringing the quality up. Factory Zero is the first start-up that has successfully built an installation module that is not only smaller, better and smarter, it’s also cheaper and it looks great.

The E=0 team constantly keeps its finger on the pulse of the European market, on the lookout for innovative suppliers capable of developing Net Zero Energy products.
