Case in point: Microsoft France is headquartered at Paris’ EOS Generali building, which has garnered earned substantial environmental certifications.

The building, located in the city’s Issy-les-Moulineaux area, achieved both BREEAM (Building Research Establishment Environmental Assessment Methodology) In-Use and HQE (High Environmental Quality in Use) Exploitation® standards.

The project, jointly initiated by the owner, Generali Real Estate, and the main lessee, Microsoft France, is a first in western European country; improving overall environmental performances.

The building, designed by international architectural firm Arquitectonica, has improved the environmental performances of the site and have been able to generate energy savings of more than 25 per cent.

The certifications testify to the excellent quality of the ecological and sustainable management and operation of the real estate complex.
