The 10 houses of Hem are the first homes rehabilitated in France zero energy any form of consumption guaranteed for 25 years. The performance in rehabilitation is superior to the RT2012 and the site by house lasts only 3 weeks.
Energiesprong is an initiative initiated in the Netherlands in 2013. Vilogia tested in France the first prototypes of this approach on 10 houses built in 1950 in Hem near Lille. Vilogia aims to rehabilitate 500 homes over 5 years using the same method. The Energiesprong method is as follows: using the current technological tools (digital and industrial method) to rehabilitate a dwelling in 3 weeks at Energie 0 and guarantee this Energy 0 objective for 25 years. Thanks to this guarantee, the tenant is protected from fluctuations in energy costs and the lessor invested in the real performance of his building.
The first prototypes have made it possible to test the implementation of technical solutions (external insulation, heat pump, photovoltaic panels, factory production of the various parts) and to obtain a house with energy 0 (performance superior to the current RT2012) 25-year guarantee via a Global Performance Market (Design Realization Operation Maintenance). The next step is to offer the tenant a couple rent + guaranteed charge integrating both the energy bill, equipment maintenance and rent.
The production of renewable energy by photovoltaic panels located on the roof is 6,000 kWh guaranteed per year. The consumption of housing for cooking, hot water, heating, ventilation is 3000 kWh guaranteed per year. The tenant therefore has an annual "energy package" of 3000 kWh / year to cover his domestic needs (TV, ironing, internet, lighting, ...). The dwellings are delivered in May 2018. For the 10 housing units the construction lasted 3 months. From the delivery, a monthly point is organized to evaluate the energy production, the energy consumption and the level of support necessary for the tenants. An annual point makes it possible to evaluate the achievement of the objective Energy 0 on average over the year.

Owner approach of sustainability
Vilogia is part of the three pillars of sustainable development:
At the environmental level, Vilogia is the social landlord who develops the most passivhaus certified projects in France (600 homes by 2020). Vilogia is committed to renovating by the year 2022 500 standard Energiesprong homes.
At the economic level, Vilogia has developed internal tools to optimize construction costs and integrates the overall cost into its financial matrices. Vilogia also studies the impact of the overall cost in its investments.
At the social level, Vilogia launched 10 social innovation projects throughout France (participative housing, shared gardens, circular economy, urban agriculture, ...)
The residential site of Hem consists of sets of houses in R + 1, structured by small islands of 2 to 4 houses. These islands are largely surrounded by gardens at the front and at the back, and are composed of brick facades and four-sided tile blankets. The project retains this spirit by backing a new facade with a brick cladding, new white PVC joinery, while bringing a dose of modernity to the roofs, breaking the two sides in gable. These roofs are completely covered with photovoltaic panels. The interior of the accommodation is improved by small touches of use, thanks to the wood hugging in the rooms which are occasionally expanded to become an office.

This equipment allows to have in a single machine all the uses of housing: Heating, Ventilation and production of Hot Water Sanitary. Easily accessible directly from the outside, it ensures easy maintenance by the operator.
NeON2 Photovoltaic Panels
Management / Others
The installed panels are monocrystalline cells, allowing annual production on the 53 kwc project, with a module efficiency of 19.5%
The project is located in a residential area of the city of HEM, in a housing complex consisting of a hundred houses. These houses in R + 1 are assembled to compose sets of 2 or 4 houses, all in a wooded setting consisting of many gardens at the front and back of houses.

A global approach to renovation that addresses both: lower consumption, renewable energy production, performance guarantee and tenant support.
A rehabilitation of 10 houses of the 50s realized in 3 weeks by house.
Houses once renovated to energy 0: the production of photovoltaic energy is equal to the total consumption of housing
A guarantee of energy performance 0 over 25 years
A support of tenants the first year to reduce their energy consumption
