For the construction of a new laboratory building with offices and server room, the electrical system is to be built from the middle voltage supply. To the extent of the plant belongs a transformer station which is to be integrated into the medium voltage ring of the AG.

Power installations and equipotential bonding VE301. The main low-voltage distribution system (NSHV) of the building is supplied via 2 outgoing panels, each with a hermetic oil transformer. The NSHV is divided into a part A and a part B by means of a coupling switch. From Part A, the supply of a centralized modular UPS system for the uninterruptible power supply of the server room and individual consumers takes place. The supply of the subdistributors for the supply of the individual floors (2.UG-3.OG) takes place alternately from part A or B of the NSHV. Cable laying for the power supply of the office and laboratory rooms mainly takes place via cable routes and channels. In order to reduce the formation of harmful flue gases, halogen-free cables are generally used for the installation. For the offices media columns are provided for receiving the installation equipment. In the laboratory rooms, only the connection cables for the separate sub-distribution boards are installed in the laboratory lines.

The lighting system is divided into a general and safety lighting system. As light sources LED lights are used in all areas. A group battery system is provided for the emergency lighting. The lighting is controlled mainly by the building automation. Only for technical rooms and toilets switches and presence detectors are provided. For the power distribution in the server room, busbars with corresponding tap-off units are to be installed for connecting the server cabinets and LCPs.

For part of the technical rooms, a double floor is to be built.
