ARCHITECTURE FIRM RAGUENEAU & ROUX GROUPE A26 WINS PRIZE FOR THE BIOLOGY-HEALTH CLUSTER AT BORDEAUX UNIVERSITY
The Université de Bordeaux's biology and health cluster won an award from EGF-BTP in its regional "Innovating for a sustainable world" competition. Carried out under a global public performance contract, this project involved the construction of a research building and the restructuring of a practical work building. At the prize-giving ceremony, the jury was particularly keen to highlight the architectural handling of the technical requirements by the Ragueneau & Roux Groupe A26 agency.
Alongside Vinci, GTM Bâtiment Aquitaine and Egis, the architectural firm Ragueneau & Roux has completed an exemplary project for the Université de Bordeaux's biology-health cluster. The 49-month project involved the complete renovation of the practical work building (insulation, joinery, electricity and the creation of monumental staircases on the façade) and the construction of a new 21,000 m2, seven-storey research building.
THE OPERATION'S ARCHITECTURAL SIGNATURE IN THE SPOTLIGHT
In awarding the prize, the EGF-BTP jury highlighted the project's architectural proposal:
"The spines on the facades that serve as sunbreakers are an architectural landmark of the research center, as is the monumental staircase in the practical work building: the technical requirement of providing emergency exits has become a genuine architectural proposition, coupled with a benefit in terms of use".
For example, users can use the staircases in the practical building as terraces during their lunch breaks.
AN EXEMPLARY FULL BIM ACHIEVEMENT IN TERMS OF ENERGY SAVINGS AND CARBON FOOTPRINT
The consortium placed reuse and limiting the carbon impact of construction at the heart of its approach. The entire new research building was constructed using locally-produced, low-carbon concrete, which was awarded the HQE BDE 2016 label.
Beyond the architectural point of view, the integration of the structural spines on the facades will also enable better control of interior temperatures: no air-conditioning system has been installed in the offices.
Last but not least, the use of full BIM has enabled us to limit carbon emissions while guaranteeing delivery that is perfectly identical to the prospects presented during the tender phase.
"We are very proud to have contributed to the realization of this exemplary project. Transforming technical and usage constraints into architectural contributions was a real challenge, but we're delighted to receive this award, which recognizes our approach as well as all the work carried out by the consortium."
