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.
