Making the site’s problems into environmental plus points

Transforming the site’s problems (electromagnetic, acoustic, atmospheric, pollution, risk of flooding) into positives  
A space bordered by high voltage electricity lines is transformed into a humid nature reserve, ensuring biotic continuity between the two banks.
The most polluted spots are neutralised using watertight basins which are home to fauna and flora from humid environments

Creation of acoustic protection on the A86 viaduct using photovoltaic panels  
The Ponkawall, an urban design proposed by Philippon-Kalt for the eco-district, acts as a noise reduction wall, produces renewable energy and, via its QR code, creates an interface for local interactive communication between all the district’s stakeholders. It is an idea that could be replicated on other sites throughout the country.

Energy: a systemic approach

The ambitious energy specifications can be modified to cope with changes in energy regulations (phase 2: 80% Passive / 20% energy-plus-buildings).
The energy consumption/production is calculated on an overall basis, based on renewable energy produced by the whole eco-district and not by the building as the labels require.
The political choice of a district heating network is intended to be used to extend to older buildings in the city centre an environmentally-friendly network including 60% REn using local geothermal pumping.
Experimental systems are planned for smaller buildings.


Recovery of materials produced by demolition

Urban lighting created by reuse

The modern-day “gleaners”, or urban foragers, illustrate Bellastock’s work in the building of the eco-district: experiments on reusing in situ, presence at demolition of the Printemps warehouses, and making its laboratory Actlab available to artists, architects, landscapers and designers.
