ES EnviroSustain’s main concern – reflected by its name – is environment and sustainability. Since founded in 2001 by Birgit Memminger-Rieve PhD and Frank Burchardi the company has developed into a Europe-wide consulting firm for the real estate industry. Employed at the Frankfurt, Stuttgart, Berlin, and Flensburg branches, the interdisciplinary team of architects, constructional engineers, building services engineers, environmental engineers, and geologists work in the interest of international clients.

The company offers extensive consulting services for existing and new buildings including technical and environmental due diligence as well as energy efficiency and sustainability of buildings. This encompasses energy audits, design and monitoring of energy efficiency measures as part of ISO 50001 energy management, project- and construction monitoring, Green Building certification with a focus on LEED® and BREEAM and sustainability consulting on portfolio level including GRESB and Environmental Management approaches.

Over the past 15 years this has lead ES to an impressive track record of green building certifications and due diligence across Europe with a focus on existing commercial buildings. To ensure a high level of quality for their clients and to share experiences with others ES is engaged with several real estate specific sustainability organizations such as the German NSO of BRE named TÜV Süd/DIFNI, DGNB, US Green Building Council and is a founding member of the German Green Building Association (GGBA).
