Projects focusing on renovation, innovation and reliability in the construction process
To expand renovation massively, it is essential, first, to have good knowledge of the existing building stock to know where we stand, measure the progress made, and determine the work still needed and to make renovation strategies more reliable at the level of a territory or building stock of a real estate company or housing operator.
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.
