Clean rooms are very energy-intensive.
In 2015 a study imputed 80% of LAAS energy consumption to its clean room which represents 7% of its surface.

Since 2018, many actions have been taken to reduce this energy consumption while maintaining the nominal operating conditions of this platform: modulation of extractions, heat recovery on extractions, recovery of "fatal" heat, better monitoring and management end, photovoltaic installation, LED lighting, ...

The result: this work, coupled with that of building A, enabled a gain of nearly 40% in electricity and even more in gas!

The investment of nearly €2 million was financed by the CNRS and the recovery plan following Covid. The return on investment is estimated between 2 and 5 years depending on current energy costs

If you want to know more, do not hesitate to read the detailed presentation of these actions that was made at the European Symposium on Nanofabrication Research Infrastructure - ENRIS 2023: "Optimization of the energy consumption of the LAAS-CNRS micro and nanotechnology platform"
