A building of High Environmental Quality, recognised by Europe

Committing to high environmental quality in constructions has enabled Lyon Confluence to ensure that a new district of innovative and comfortable buildings is created from the design phase on. The approach has been recognised by the European Commission.

The High Environmental Quality (HQE) of the buildings is the result of the practical application of Lyon Confluence's sustainable development policies. Lyon Confluence's commitment was quickly embodied in the district with the creation of blocks A, B and C, all flagship buildings in terms of HQE. What did they include? Housing and offices organised around a central garden whose energy needs were 40% lower than classic buildings, 80% of which were met by renewable energy sources (wood-fuelled boiler and solar cells). However, it also meant more comfortable spaces were created because of the highly exacting standards for thermal and acoustic insulation.

Performance and innovation standards

How do you get such excellent results? By implementing bioclimatic design in the buildings, by encouraging dual aspect housing units which benefit from more natural light and by fitting external insulation so as to provide greater thermal comfort in both winter and summer without using air conditioning. Demanding standards for energy performance and quality of life meant that these blocks were recognised by the European Commission's Concerto initiative. To make these standards a reality strict specifications for the urban development, architecture and environmental aspects of the project (sustainable buildings) were imposed on private operators. Competition between the private operators was opened up by fixing the price of the initial land purchase which put the emphasis firmly on the HQE quality of their proposals.
