The four buildings of the national metrology and testing laboratory located in the Trappes-Elancourt business area, which date from the 1970s, have not seen any major work since their construction. Today they are considered true thermal sieves.
Work that should be completed in the fall of 2023 has been started to improve the thermal quality of the buildings. They must enable an energy gain of 25%, or 1.6 million kilowatts/hour per year. The buildings, which total an area of approximately 50,000 square meters, will be insulated on the outside with biosourced materials, and the joinery completely replaced. The State is injecting 5 million euros into the operation.
Thermal renovation model
The project is part of the objective set by France to reduce the energy consumption of its public tertiary buildings by 40% by 2030 and by 60% twenty years later. This concerns State real estate, local authority buildings and the health sector.
According to Bercy, more than 3.8 billion euros, including 2.7 billion as part of France Relance, have been invested since 2019 to renovate nearly 4,000 state buildings. “These are considerable sums, tens of thousands of tonnes of CO2 are avoided. It is the equivalent of the annual domestic consumption of a city of 200,000 inhabitants which will be saved,” indicated Bruno Lemaire, the Minister of the Economy during a recent visit to the site of the National Metrology and Trappes test.
Nanomaterials, artificial intelligence and quantum
The renovation of the laboratory will in particular serve as a model. The latter specializes in the certification of innovations with a view to placing them on the market. In particular, it carries out tests and analyzes of consumer products, energy and the environment, medical/health and transport. The laboratory is particularly interested today in three new subjects: nanomaterials, artificial intelligence and quantum. The establishment recently created an institute dedicated to nanotechnology metrology to measure the infinitely small. It has a unique microscope in France for calibrating instruments for measuring nanoparticles.
