5 Chinese cities designated Sino-French Pilot Eco-cities and engaged in HQE™ development certification with the support of the CSTB Group
At the 14th edition of the International Conference on Green and Energy-Efficient Building in Zhuhai, China, on April 2 and 3, 2018, the Sino-French Pilot Eco-City Prize was awarded to five cities across the country, in the presence of Qiu Baoxing, president of the Chinese Society for Urban Studies (CSUS) and former vice minister of construction, Étienne Crépon, CEO of the CSTB, and Patrick Nossent, President of Cerway.
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.
