As part of a heritage rehabilitation, INRA is in a dynamic to renovate part of its buildings inside the Duclos estate. Through its activity, INRA has the desire for the ASTRO-EST building to optimise both architectural and technical energy performance for heavy renovation. The renovation of the ASTRO-EST building is part of the restructuring of the INRA Antilles-Guyane site, which was outlined in the 2013 programming study. The main part of the renovation work is to: — seismic reinforcement of the building according to the EUROCODES in force, — the energy renovation of the building, — the fitting-out of the interior spaces to accommodate the administrative services of the site.
