Since its creation, SMC2 has wanted to integrate its entrepreneurial action into a socially responsible and sustainable approach with very high environmental quality innovating buildings.


Companies must work for the common good by protecting the environment and effective economic action. This virtuous belief drives our teams and our daily action to offer our clients simple and functional solutions by meeting the company’s economic and environmental challenges.


Architecture, aesthetics, design and innovation are also the driving forces behind our creativity.


We nurture them through dialogue and exchange with all our partners: architects, local authorities, institutions..


SMC2 designs buildings that are part of a realistic environmental approach.

By combining exclusive building methods and low environmental impact materials, SMC2 limits waste and excess consumption to save the planet and fulfill the pleasures of regular sports activities


Timber constitutes the largest part of SMC2 structures.
The only material with a negative CO2 footprint, it does not contribute to the greenhouse effect. Even better: its processing into a construction products requires 130 times less energy than aluminium and 60 times less than steel. SMC2 only uses European timber from sustainably managed forests. As for the other materials used, they are 100% recyclable, in particular the textile membrane which is reconditioned using a specific process.


SMC2 has been able to reduce the density of the building materials used, and therefore the energy required for their manufacture. The structures are also designed to minimise operating energy costs.



SMC2 sports facilities have an LCA (Life Cycle Analysis) to assess their true environmental impact on 12 targets:


  • Greenhouse effect
  • Ozone layer


Our LCAs benefit from a critical review from the Saint-Etienne eco-design hub to make sure that they are part of a realistic and real approach.

Our design choices are measured and integrated into an environmental solution that is optimised to protect our environment.

SMC2 received financial support from the Rhône-Alpes region for the implementation of its LCAs

SMC2’s carbon footprint gives an overall measure of the company’s activity on global warming. It has identified significant reduction opportunities in terms of CO2 emissions.

For example, following its 2012 carbon footprint, several actions have been implemented, including:

  • A wood-fuelled boiler on the new Mornant site. This installation has made it possible to avoid natural gas, which releases large amounts of CO2.
  • The installation of home automation systems for lighting management (motions sensors, light intensity regulator). Electricity consumption remains stable despite the increase in the area occupied following the change of site.
  • The optimisation of our teams’ travel (rail travel is preferred to air travel).

The 2013 carbon footprint showed a positive impact of the actions implemented.
A saving of 18 tonnes of CO2 has been recorded on the “Energy” and “Travel” items over the last 12 months. This saving represents, for example, the equivalent of the greenhouse gas emissions of a diesel city car travelling three times around the circumference of the earth at the equator.
