==== Air Cooling/Air Conditioning ====

The seminar room and the meeting room are further equipped with a local air cooling system which cools down the standard ambient air supply in order to avoid people to get tired in meetings.

The server room on the office floor is equipped with a local air conditioning system.

The analytic labs in the center of the lab floor are equipped with a dedicated air cooling device that maintains a temperature of 20°C by active cooling. Since there is no possibility for heating this system is only working downwards. The intention is to protect the machines. Staff working here has to take measures against freezing, if applicable.
