Dean Lewis, president of the University of Bordeaux, said, “We are a research-intensive university with many laboratories in health biology, and this is very consuming. We want to take concrete action on 10 of them, because if we reduce energy consumption by 15-20% (mainly electricity), it exceeds the consumption of the whole enterprise. For example, a targeted approach that does not exempt the University of Bordeaux, which enrolls 54,000 students, from expected savings measures by lowering the heating or air conditioning of the computer servers by a few degrees.
Avoid wild cuts
“We’ve toured our large energy-intensive labs, and we’re wondering if we can reduce the load there or even postpone particularly energy-intensive operations and thus avoid wild outages.” Among these chasms in terms of energy consumption is, for example, the European Institute of Chemistry and Biology (IECB) in Pessac. “For example, there are 150 constantly working extractors, -84°C and NMR (nuclear magnetic resonance) freezers,” says the president of the university. He also points out that 250 fume cupboards (ventilated laboratory enclosures) are continuously operating to renew the air three times an hour at the Institute of Molecular Sciences (ISM).
For example, the measurement and imaging equipment that Neurocampus is equipped with also significantly increases the consumption of the enterprise. “There are pet stores there that we cannot even stop,” the president emphasized. In Pessac, the clean room (the concentration of particles is monitored for research purposes) causes a major panic of the counters.
Concerned that the voltage in the power supply may drop from 240 to 220, the university administration has also started a kind of check on this equipment to see if the maintenance providers can work well under these conditions. power.
Also update the power filters
With the transfer of the university heritage of the state to the University of Bordeaux, between 10 and 15 million m2, the institution had time to define its energy sieves. “Already 35% of our real estate assets have been upgraded (last delivery in 2023) and a maintenance budget for 25 years, which we have not done before,” claims the president. It remains a large project estimated for the remaining heritage or 400 million euros over 20 years.
“We don’t have a lot of m2 by national standards,” Dean Lewis said, adding that 29 hectares were identified in the build-to-let model and could be sold. The idea is to ensure a certain consistency on campus, for example by prioritizing student housing.
The institution is also considering equipping itself with more photovoltaic panels (today 12,000 m2) and the heating network (biomass geothermal energy) in Talence, Pessac and Gradignan will cover university structures especially from 2024. winter” but about anticipating an ongoing energy crisis.
