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.
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.
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.
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.
Safety and wind comfort for the Cultural Center of the Stavros Niarchos Foundation
In the center of a large city park facing the sea, south of Athens, the National Library of Greece and the Greek National Opera have relocated to exceptional new buildings designed by architect Renzo Piano. The design of these buildings, inaugurated in early 2017, relied on the expertise of the CSTB in two areas: aerodynamics in engineering works and wind comfort in urban spaces.
Stepped timber frame with invisible seams
Wooden beams make up the stepped structure of the huge roof covering the Aqualagon, the future water park of Marne-la-Vallée. The beams were made by Arbonis, using an innovative assembly technique, which received a favorable ATEx assessment in early 2016.
Laboratory measurements and on-site measurements: getting closer
Thermal and acoustic insulation made of recycled paper, or cellulose wadding, is used in loose fill or in panels in buildings. A study initiated by a working group of industrial manufacturers with the CSTB explored to what extent the thickness of this loose fill insulation is subject to settling, over time. This is a major challenge in the context of energy transition. The goal is to assess this component's actual contribution to the energy performance of the building envelope.
The offering of the CSTB: ATEx and regulatory flexibility
On June 21, the CSTB organized a day-long event to guide stakeholders in innovation. A round table discussion focused on innovation in connection with the regulatory flexibility recently proposed for the construction industry. In order to support stakeholders, the CSTB is expanding the scope of the Technical Experimentation Assessment (ATEx) to new solutions that have been developed, based on the regulatory flexibility that has made it possible to use means other than those described in the regulations.
3rd Ifop-CSTB innovation survey: environmental performance, a driver for innovation by construction VSEs and SMEs
The 3rd survey conducted by the Ifop for the CSTB among construction companies of less than 500 employees (VSE/SME) confirms the importance of innovation in the view of company directors, especially innovations that improve energy performance and reduce the environmental impact of materials.
