Energy-intensive building

The construction of 12 passive and adaptable dwellings is part of the rehabilitation of a housing estate "La cité du Centenaire", which comprises, in its original situation, 7 identical 4 levels buildings repetitive as well as 2 batteries of 15 garages. Each building has 12 apartments, totaling 84 units.

The aim of the intervention was to:

· The demolition of the 30 garages and a 12 units block;

· Energy retrofitting of 6 buildings, or 72 units;

· The construction of a building of 12 apartments on the part of the land made free after demolition of the garages;

· Development of the surrounding area.

Owner approach of sustainability

The rehabilitation of the centenary city aims to improve the living environment of the occupants, revitalizing the entire site, creating outdoor collective spaces, favoring the modes of soft travel ... New places of conviviality are thought such as a protected area under the piles, a community kitchen garden and a children's playground, in order to encourage intergenerational exchanges.

Architectural description

The project is part of a global environmental approach. Particular attention is paid to the energy aspects of renovated buildings. Indeed, all renovated buildings are designed on the basis of the general principles of passive construction. This project includes the demolition of two blocks of garages and an apartment building as well as the "light" renovation of 4 blocks of apartments and the construction of a new apartment building. The new building with 12 apartments is passively certified. The apartments are serviced by a vertical circulation area open on the outside at the rear, which limits the problems related to the common spaces in terms of maintenance, vandalism and nuisance and allows a larger budget to the development of the surroundings at the right of the latter to create an intermediate zone in the spirit of an interior patio intended to enhance access to housing. The accommodations are of the crossing type and have a terrace and wide bays in the South. They are of medium type with 2 and 3 rooms.

Indoor Air quality

    - Choice of construction materials without formaldehyde, plaster based on natural gypsum. - Mechanical dual-flow ventilation with filtration to ensure good air quality.

Health & Comfort

    - High natural light in living rooms and bedrooms - Natural sun protection by the presence of a screen of trees in the south complemented by balconies and additional protection on the top floor. - Crossing apartments allowing for effective natural ventilation.

    Rohbau / Passivsystem

    The Hermine 66 ® passive chassis developed to be the most efficient on the market today. With a warm design thanks to the combination of wood and aluminum exterior. Designed for the new energy and environmental challenges of sustainable development. Optimizes the glass surface for better natural lighting. Increases safety and acoustic comfort with glazed glazing. easy maintenance.

    The Hermine 66 chassis is a passive mixed chassis (wood-aluminum) and has the PHI approval (Uf = 0,60W / m²K).

Urban environment

The city of Centenaire is located in the heart of an urban area well served by public transport (bus and metro lines), close to public facilities (nurseries, schools, hospitals, etc.), shops and services, necessary base to project a city in the sustainable. In order to reduce the car pressure due to the through-ways, Soft travel modes are favored on the site and the surrounding areas are treated accordingly, both for pedestrians and for cyclists. Specific equipment for bicycles is provided and the pedestrian paths connect the site to the various existing pedestrian networks.
