The program of "La Grande Halle" concerns the development of 20,000 m² of offices divided into 3 buildings in the form of a campus. La Grande Halle is part of a wider redevelopment project ("depollution") of a 2.7 ha industrial "brownfield" ("Gerland 75") developing 50,000 m² of housing, offices and businesses involved in the revitalization of the district Gerland in Lyon which will be delivered in 2020.
Designed by Reichen and Robert Associates, "La Grande Halle" integrates the restructuring of an existing hall. The building offers a range of services for employees, all resolutely oriented towards urban biodiversity with 900m² of landscaped gardens. This strategic axis of Gecina's patrimonial policy is the main focus of this program.

Sustainable development approach of the project ownerWinner of a competition organized by EDF to relocate the management of SEPTEN of EDF, we worked to make this building as durable as possible with materials such as wood and stone. The objectives: to obtain the HQE certification Excellent level and the certification BREEAM Very Good. This is not our first green building. The strong ambitions expressed in design allowed us to obtain in phase the realization of 2 new labels: Low Carbon Building and Biodivercity. La Grande Halle project is part of the dynamic reconstruction of the city on the city. The articulation between the preserved Halle (wall, piercings, and volume of the roof) and the new buildings allows the neighborhood to evolve in accordance with the existing fabric. The volumetry in R + 5, the composition in small assembled volumes, the work of inclination of the roofs make this project an urban building integrated.
Architectural descriptionThe wood (70% of the wooden facades, 1700 m2 of wooden floor in the renovated hall, timber frame in the hall, insulation of wooden wool blankets, larch-stone terraces), stone (golden stone walls of The preserved hall, natural stone paving in the gardens). Creation of more than 900 m2 of gardens. Use of geothermal energy for the heating and cooling of the building. The project is a homogeneous and introverted whole. Patio buildings organize a succession of interior / exterior spaces that enrich the lives of users. In this way, it allows the concentration and the serenity of the future occupants.
Building users opinion
No feedback for the moment, the building will be occupied in November 2017
If you had to do it again?
Everything except geothermal energy (very complicated administrative authorization and very long, complex studies).

Real final energy consumption
- 0,45 W.m-2.K-1
Estimated actual consumption in design at 234 kWhep / m² / year (including office automation, restaurant, off-RT). The initial consumption can not be given because the building did not have the same use before renovation.
