Exploring scenarios to boost neighborhood energy performance
Innovating in the area of urban development in neighborhoods and citywide while assessing project energy performance. The CSTB supports developers, local authorities, industrial companies and operators. Specifically, it offers its expertise in the dynamic modeling of energy systems using the new DIMOSIM software package. In 2014, the CSTB assisted the EPA Plaine du Var (Plaine du Var Urban Development Agency) with its plans for the Nice Méridia neighborhood.
Measuring the performance of a water heat recovery system
Gray water heat recovery systems can instantly capture energy from household wastewater, thereby improving the thermal balance of buildings. To measure the actual performance of these systems, the CSTB has been offering tests in its Cofrac-accredited laboratory since September 16, 2014.
New hospital for Ajaccio: a 100% BIM project
Design work for the new hospital center in Ajaccio began in 2014, with handover scheduled for the end of 2017. This complex project is pioneering in many ways. At the request of the community of Ajaccio—the project owner—it uses Building Information Modeling (BIM) as its work tool, from design to operation. As a member of the project consortium, the CSTB is specifically responsible for correct usage of the BIM protocol, which manages digital modeling data throughout the life of the building. The result is a powerful contribution to mutual understanding between stakeholders and reliable project supervision.
Portable indoor air pollutant detector
A new detector makes it possible to monitor and analyze indoor air pollutants, particularly fungal contaminants. Developed from research conducted by the CSTB, it received the Innovative Environmental Techniques Award at Pollutec 2014. Its practicality and reliability make it a prime solution for improving indoor air quality. It offers promising industrial applications in France and around the world.
New systems for measuring actual energy performance
The challenge consists in predicting and demonstrating the energy performance of buildings. The measurement tools developed by the CSTB and its partners are designed to give project stakeholders the assurance they need by offering verification of the outcomes achieved using two methods: REPERE, which assesses the actual long-term performance of occupied buildings, and ISABELE, which measures unoccupied buildings at a given time.
Initial feedback on the Energy Performance Contract
The Centre and Alsace regions of France pioneered the use of the Energy Performance Contract (EPC) for renovating and operating their schools. As part of a study carried out on behalf of ADEME, the CSTB analyzed both projects over three years, from design to full use. The summary of lessons learned was finalized in November 2014 and provides the first operational feedback on the EPC scheme in France. It is an essential guide for widespread deployment. Its recommendations are also extremely valuable to all project ownners and operators seeking sustainable improvement of energy performance in property assets.
Promoting energy upgrades of buildings in Colombes
The city of Colombes on the outskirts of Paris wanted to communicate about the challenges of energy upgrades of buildings and identify stimulus measures. As part of this initiative, it commissioned DRIEA, CEREMA and the CSTB to research specific case examples, the results of which were published in May 2014. The role of the CSTB was to analyze system upgrade scenarios in two condominium buildings.
Studying electromagnetic fields with the Phéline platform
On October 3, 2014, the CNRS, Joseph Fourier University, Institut National Polytechnique of Grenoble, University of Savoie and the CSTB signed a partnership agreement to pool their expertise in electromagnetism to form the Phéline platform. As more and more devices and equipment generating electromagnetic fields appear in our environment, the challenge is to fully understand the levels at which people are exposed in order to meet the expectations of state and the public.
Optimizing use of high performance concrete
With high-profile uses in the mesh walls of the Musée des Civilisations de l’Europe et de la Méditerranée in Marseille and the Louis Vuitton Foundation in Paris, fibre-reinforced concrete is used to create complex architectural components. To optimize its use in terms of performance and cost, a working group led by Lafarge Group in partnership with the CSTB developed new benchmarks for sizing this innovative material.
