What Greenaffair does

Founded around 2003 and headquartered in Sèvres, the company combines the roles of consulting advisor, project owner assistance, and engineering studies bureau under a single multidisciplinary practice covering carbon, energy, biodiversity, circular economy, indoor air quality, ESG strategy, and sustainable real estate certification (HQE, BREEAM, LEED, WELL, BBCA, BiodiverCity, WiredScore, OSMOZ). It complements project services with proprietary digital and measurement assets, most notably the 2024-launched 'ema' platform for real-time construction-site environmental monitoring, the Datalab for bespoke digital tooling, the Monitolab measurement cell, the Green Académie training organization, and an internal R&D incubator on building resilience and vulnerability.

The firm serves large real estate investors and property companies, REIMs, real estate developers and construction firms, large enterprises with ESG obligations, and luxury/retail brands with real estate holdings.

The company is privately held as a SAS with founder/President Sébastien Matrat, and shows no disclosed external funding.
