Behind the scenes at the Silver BIM Awards 2018: the Jardins de l'Arche Tower in La Défense with the CSTB
The winner of the Silver BIM Award 2018, the Jardins de l'Arche tower in La Défense, will feature three hotels, offices and an observation platform at the top, by 2022. With its 54 floors, standing 200 meters high, this project won in the category of new construction projects with an area of more than 40,000 square meters.
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.
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.
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.
Synerbois assists SACBA with its wood process study
A manufacturer of a solid wood process for walls and structural floors, SACBA (Development and Construction Company of Agricultural Buildings), an SME located in France's Aquitaine region, called upon Synerbois, which includes the FCBA (French Technology Institute for Forestry, Cellulose, Wood Construction and Furniture) and the CSTB (Scientific and Technical Center for Building) to characterize the performance of its wood process, called Bosco CLT, to be used in high rise buildings.
