THE GROUP

Specialist in Sustainability since 1993

BACKGROUND

Building on his expertise in energy issues and sustainable development in the construction sector as a solar energy expert for the Ministry of Housing, Michel Raoust founded the thermal engineering firm Raoust in 1993 to support the emergence of HQE (High Environmental Quality) standards in construction. He contributed to one of the five pilot projects that served as the foundation for drafting the very first HQE reference framework.

During the Grenelle Environment Forum, the “Cabinet Raoust” became “TERAO SARL” in 2007.

In 2015, TERAO adopted a new governance structure to strengthen its growth both in France and internationally. Guillaume Rousseil joined the company alongside Aymeric Novel (TERAO’s Operations Director) and Michel Raoust, who was responsible for innovation.

In 2022, ATIXIS Holding became the majority shareholder of TERAO. This technical project management and multidisciplinary engineering firm brought complementary expertise to TERAO. With its subsidiary in Vietnam, a development synergy was created with TERAO’s subsidiaries in China and Singapore.

On September 30, 2022, after ensuring a successful transition with the new majority shareholder and TERAO’s entire executive team, Michel Raoust, the founder, retired. All TERAO and ATIXIS employees thank him and wish him great success in his new life!

KNOWLEDGE TRANSFER

After over 30 years of dedication to sustainability, Mr. Raoust invests now all his efforts in knowledge transfer so the new engineers can keep on improving his undertaking.

INNOVATION

TERAO takes advantage of the pioneering culture initiated by its founder, still deeply anchored nowadays. Indeed, our teams will provide systematically innovative solutions to the project team.

INTERNATIONAL DEVELOPMENT

TERAO carries out projects over the 5 continents, especially in Asia and Latin America where our development drove us to open local operational branches.

TERAO PIONEERING ROLE

TERAO stands at the forefront of Sustainable Building expertise owing to its 20 years of experience. TERAO and its collaborators have been participating actively both in France and abroad in the field of sustainable building and in emergent technologies thanks to publication of studies, calculation software editing and thanks to its participation to national and international working groups.

This everlasting culture of innovation enable us to offer solutions that anticipates the needs of project managers and guide them toward more and more high-performing and positive-impact buildings.

ENVIRONMENTAL RESPONSIBILITY

Environmental responsibility is our fuel. Beyond our obvious will to reduce depletion of natural resources, we give a particular attention to daily business reality of the different stakeholders so that good practices generalize and are not seen as a cost but rather as an added value.

INNOVATION

Innovation is our main focus at TERAO. Indeed, our company started with the conception of one of the first thermal simulation software as well as the creation and the execution of the first HQE (High Environmental Quality – French Green Building Standard) procedure. Nowadays, TERAO is one of the most referred engineering company to support energy performance.

Thanks to a multicultural firm that enhances a continuous pro-activity with innovative practices, we remain at the top of the performances within the built environment. While staying focus on the major overall dynamics, we work independently without following the trends.

Our solid international presence allows us to benefit from valuable feedback from the sites and customers and to constantly challenge our knowledge. Moreover, our clients take advantage of our high-quality added values through significant transfers of knowledge.
