Operating cleanrooms requires expenditure that is reflected in the operating costs. Part of the operating costs of cleanrooms is due to energy costs. Operating a cleanroom requires electricity, heating and cooling.

It is in the nature of things that companies try to keep operating costs low. Due to the (previously) low energy prices, the high operating costs due to personnel and the high quality requirements in the GMP area, efforts to install energy-efficient systems or optimize the existing system have so far been minimal. Since 2021/22 at the latest, when energy prices rose and there was even talk of power blackouts, companies have been sensitized. Companies need to be competitive in order to survive on the market. Lower operating costs help to increase competitiveness. In addition, companies are forced to reduce their carbon footprint so that we as a society can achieve climate neutrality in the near future.

Therefore, when planning new cleanrooms and optimizing existing cleanrooms, energy efficiency must be considered as an important pillar in addition to quality specifications and operational safety.
