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.
Enhancing the resilience of buildings for the well-being of their occupants
How do you explain uneasiness, physical discomfort, or even severe illnesses in occupants of a building, without clearly discernible reasons? Sick building syndrome, recognized by the World Health Organization (WHO) since the 1970s, is the manifestation of psychological and medical conditions directly associated with a 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.
Higher education in Ile-de-France gets started with BIM, with the CSTB
The Public University Development Agency of the Île-de-France region, or EPAURIF, and the CSTB have begun working together on BIM technology. Their objective: to help universities and other institutions of higher education to implement this new way of working, to improve the construction and operation of their building stock.
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.
First step towards BIM for the medical center in Brest
The Regional University Medical Center (CHRU) of Brest enlisted the help of the CSTB to take advantage of the opportunities offered by BIM for operating its buildings and facilities. In 2016, the CSTB carried out an audit of the technical software being used at the time by the CHRU, and assessed the possibility of combining them with a BIM database. A first step in the digital transition.
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.
Developing a method to assess interactions between urban systems and biodiversity
Measures to protect biodiversity have been reinforced in the regulations on urban development, particularly with the Law on the Protection of Biodiversity adopted in 2016. The objective is to provide the stakeholders of development and construction with indicators and tools to assess what impacts buildings and neighborhoods have on biodiversity.
Offering sound comfort and energy performance to the EcoCity in Champs-sur-Marne
In Cité Descartes in eastern Paris, a new EcoCity aims for architectural innovation, a better quality of life and energy performance. EPA Marne, a public urban development agency, initiated this project as part of France's City of Tomorrow program, supported by the Investment Plan for the Future.
Experimenting with concrete demolition and its reuse in situ
As part of an ambitious program of urban renewal in Stains (Paris Region), the public housing office of Seine-Saint-Denis and the association of architects Bellastock experimented with in situ concrete recycling. Concrete shells from the dismantling of social housing dating from 1960 served to build new urban structures, such as benches and outdoor paving. The CSTB provided technical support to project stakeholders in support of the circular economy.
The CSTB, BRGM, Bouygues Construction, and the HQE Association – France GBC are developing a new tool to contextualize building design: OVALEC
The four partners pool their expertise to develop OVALEC, an R&D project to help stakeholders in the circular economy. Under this agreement, they are developing a new tool to aid design and decision-making in support of the environmental quality of buildings.
