Greywater recycling: from concept to assessment
In October 2015, WisElement, a VSE, took advantage of the CSTB’s innovation advisory and support service, Ariane. Since then, it has been advancing step-by-step to increase the reliability of its innovative device for the instant recovery of heat from shower greywater. In 2016, the CSTB initiated a study of the technical and regulatory aspects of the innovation in the concept phase. The results may support a request for Technical Approval in 2017.
Stepped timber frame with invisible seams

Insulated concrete form walls: four technological leaps supported by the CSTB
2016: The industrial companies GBE and Lafarge received a Technical Approval for a cast-in-situ wall with integrated insulation and concrete skin. This system has just taken its fourth technological leap, 20 years after the emergence of the first solution of its kind on the market. The CSTB has supported the advancement of this innovation since its beginnings. Working alongside the stakeholders through the assessment procedure, the CSTB helps ensure the safety and stability of their system.
