New buildings or alterations to cleanrooms must as much as possible not interfere with the manufacturing process. The conversions were made more difficult by the fact that they are taking place in a very confined space within the existing buildings. The installations had to be GMP-compliant and be tested and qualified accordingly. At the same time, however, they were supposed to use energy as efficiently as possible.

Since 2002, we have been involved in over 100 projects for the pharmaceutical industry. Since then, all cleanrooms have been able to meet the high requirements and be qualified at the first attempt. Keeping to the schedule is very important so that the medicines can be produced on time. Since cleanrooms are very energy-intensive, they offer great leverage for efficiency improvements. We scrutinise the requirements and make it possible to realise large savings with small interventions. Through our work at several pharmaceutical companies, we can benefit from the experience of the competent plant operators and thus incorporate the operational experience, as to which systems are sustainable also in the long run, back into the new construction projects.
