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.
With Dimosim, developing an Energy Master Plan for "Pays SUD"
The municipality of Barcelonnette, Pays Serre-Ponçon-Ubaye-Durance (Pays SUD) association and the CSTB have joined forces in a collaborative research project. The aim is to study the energy strategy of these local areas in the county of Alpes-de-Haute-Provence, using Dimosim. This prospective engineering software developed by the CSTB simulates and compares various scenarios for 2030 and 2050, to improve planning for changes in the local energy system.
Heat recovery from greywater tested under real conditions
A research team of the CSTB worked on estimating the potential for instant heat recovery from greywater, thanks to the experimental installation Simulhome at the Aquasim test facility. Simulhome reproduces domestic water use realistically, in a standard-equipped housing unit.
Collective mobilization for the "E+C- Experimentation" initiative and its associated label
Jointly launched by public authorities and construction industry stakeholders in November 2016, the "E+C- Experimentation" initiative and its associated label evolved from several years of collective groundwork.
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.
