The CSTB's expertise supporting the Montpellier Sud-de-France train station
Comprising a roof made of ultra-high performance fiber-reinforced concrete (UHPFRC), with an openwork pattern of 10,000 glazed openings, the new train station in Montpellier is a technical and architectural innovation designed by Marc Mimram.
The CSTB awaits you at BATIMAT, November 6-10, 2017
The CSTB awaits you at BATIMAT for a week of appointments, talks and demonstrations. CSTB experts will be present every day to inform and advise stakeholders in the building sector, with a focus on the major challenges facing the industry, and the CSTB’s specialist areas: digital technology, energy and environmental performance, innovation, health & comfort in buildings, materials and equipment, etc.
Toward a standard format for describing objects in digital models
The deployment of building information modeling (BIM) depends on its full adoption by all construction and urban development trades. This new working method enables the various stakeholders in a project to share all information about the "objects” in a digital model of the building and city, beyond just visual representation.
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.
Improving assessment of summer thermal comfort in timber-framed buildings
A study entrusted by the public authorities and timber companies to four partners – FCBA, Nobatek, Cerema and the CSTB – produced new methods for calculating moisture transfer in the interior walls of timber construction. This will improve assessments of summer thermal comfort in this type of building.
A chimney that resists hurricanes and improves natural ventilation
The CSTB has developed a hurricane-resistant chimney, which reinforces houses in hot regions subject to hurricanes. This innovation enables a building to withstand a hurricane and gives it optimal natural ventilation, reducing the need for air conditioning.
Using BIM in technical inspections
The digital transition in the construction industry is a revolution involving the entire chain of stakeholders at each step of a project, so that the advantages of BIM for productivity and quality can be as beneficial as possible. In a project, compliance with the rules of the trade is verified by a certified control office, beginning with the design phase of the structures and continuing until the work is completed.
Urban swales to improve stormwater management
In urban areas, stormwater can cause pollution and floods as a consequence of increasing urbanization, which makes ground impermeable. As part of an R&D partnership project called Matriochkas, the CSTB is working with IFSTTAR Nantes, Centrale Nantes, the City of Nantes and the Loire-Brittany Water Agency on an urban stormwater swale system that enables permeation and retention. The CSTB is testing this full-scale solution at its Aquasim test facility.
