TAKING ROOT IN AN ENVIRONMENTALLY- CONSCIOUS RESIDENTIAL BUILD

e4

“Le Candide” is a multi-storey social housing project in France, providing 29 flats to a previously neglected neighbourhood. The project is rooted in the Wienerberger e4 concept: ecology (renewable energy sources), economy (affordability), energy efficiency, and emotion (unique quality of living).

TAKING ROOT IN AN ENVIRONMENTALLY- CONSCIOUS RESIDENTIAL BUILD

e4

“Le Candide” is a multi-storey social housing project in France, providing 29 flats to a previously neglected neighbourhood. The project is rooted in the Wienerberger e4 concept: ecology (renewable energy sources), economy (affordability), energy efficiency, and emotion (unique quality of living).

The building might suitably be described as a residential habitat, an alternative design for urban living. To its architect, it is a laboratory for ideas that provides the occupants with opportunities for evaluating “natural living” in a multi-storey context. The twin block provides a workshop for repairs on the ground floor, a vegetable garden on the roof-top, and greenhouses, a wind turbine for irrigation and a shared playground with a terrace for children.

 

CERAMIC BUILDING MATERIALS – INSIDE AND OUTSIDE

When viewed from the outside, the most striking elements of the building are its balconies. Created from woven willow balustrades, and different on every floor, they create a wave around the façade. Here, LEDs shine like fireflies at night and are recharged during the day. Brick cavity walls provide enhanced heat and sound insulation, and a better indoor climate for the well-being of all residents.

EXAMPLE THROUGH INNOVATION
The starting point for this project was an architectural competition, followed by a prize in a competition inviting ideas for low CO2 emissions solutions. This presented the opportunity to review the energy-saving facilities and propose systems to achieve CO2 emissions below 5 kg/m2a. The housing cooperative decided to implement these alterations, thereby combining architecture, building services and social engagement. New technologies were integrated into the project, such as a photovoltaic system, a ground water heat pump, waste water heat recovery and a hybrid natural ventilation system.

The district had long been neglected, so we had to go back to basics. Brick is ideally suited to that. It stands up to the passage of time.
