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

Project Summary

E=0 will support the development of home makeovers to net zero energy levels in FR, NL, UK and LUX.

E=0 will address poor energy performance of residential buildings by generating a new mass market for net zero energy retrofits across NWE. Current retrofit measures are piecemeal & not integrated to deliver whole-house warrantied performance. This trend is driven by the lack of holistic policies & compartmentalised funding.

E=0 is based on the successful Energiesprong programme in the Netherlands, delivering net zero energy (E=0) retrofits with a 30+ years performance warranty; installed within one week at a cost paid off by the guaranteed energy savings and maintenance costs (stroomversnelling.nl/initiatief/internationaal).

A net zero energy house generates as much energy as is needed for the house and household appliances. This is possible by using new technologies such as prefabricated facades, insulated rooftops with solar panels and smart heating and cooling installations. After a Net Zero Energy makeover, the house takes on a modern appearance from the outside, while inside the house is free of moisture or drafts. The retrofit greatly improves quality & comfort, leading to wider urban renewal.

This game changing approach is based on aggregating demand from the housing supply side and letting them procure a performance-based product meeting this new standard. This challenges industry and their supply chain to innovate. To widen the opportunity for supply chain integration, this E=0 retrofit market must scale up to the NWE region.

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.

E=0 demonstrator Fonds du Logement: Place Abbé Mühlendorf

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. 

Aerial view

The Kirchberg-KIEM district is situated in Luxembourg City in the south of the Grand Duchy of Luxembourg. It is today the heart of the international banking and financial place that the country constitutes. Its population is 5.499.

Site description

The site is situated in a residential area of semi-detached and individual houses next to the highway exit and large communication axis leading to neighbouring cities.

The buildings have a ground floor and 3 floors and pitched roofs. These are typical residences of the eighties with apartments including balconies. Each landing serves 2-3 apartments. Each stairwell provides an access to 4 levels of apartments and a basement. The first building of 24 units and 2 staircases will be refurbished with E = 0 techniques and delays and. The second building, planned for a classic renovation, has 3 staircases and 28 units.
The current energy class of both buildings is “G”. and they were built in 1986 and 1987. The population consists of small families. Most people are long term tenants.

Site before the intervention

« Il s’agit d’un projet pilote, donc nous n’allons pas nous limiter à faire du conventionnel. C’est l’occasion pour nous d’explorer différentes pistes en tenant compte de toute une série de contraintes : la valeur d’isolation, la densité, le poids, la valeur écologique, etc. Nous tendons vers une structure en bois avec un isolant qui pourrait être en paille ou dans un autre matériau biosourcé. Nous cherchons la solution idéale pour ce bâtiment en particulier, tout en gardant en tête l’idée de pouvoir l’appliquer à d’autres résidences ».

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.
