The department of chemistry of Justus Liebig University in Giessen, one of the institution's key departments, is receiving a new state-of-the-art facility for its research and teaching. With gross floor area of about 29,000 m², the new institute building, located on Heinrich-Buff-Ring, will house a total of six chemical institutes.

Actually a building complex, the new facility comprises three wings. Wing A, a long structure with a five-story main entrance hall, houses the "Physikalisches Praktikum," with laboratories for practical training, study rooms and classrooms. Wing B, a horseshoe-shaped structure behind wing A, is the institute building per se, with research laboratories, offices and meeting rooms. Wings A and B face onto a spacious, green, terraced courtyard. Wing C, with a large lecture hall, four smaller lecture rooms, classrooms, lounge areas and a foyer, is located to the west of wings A and B.

The building systems for the new institute building are housed mainly in its basements and in rooftop technical-systems centers. The control center for the facility's district heating and district cooling systems is located on the first basement level of wing A. The control centers for its ventilation, sanitary and electrical systems are located on the 2nd basement levels of wings A and B and in rooftop control centers. Several chillers and ventilation systems serve both wings A and B. In addition, both wings are connected to the same central hot water supply. Wing C has an underground connection with wings A and B. Wing C also has a ventilation station on its 2nd basement level, along with a control system for sprinkler and fire-extinguishing systems. The sprinkler system serves some sections of wing A and large sections of C. The fire-extinguishing system serves all three wings, with a "wet" hydrant pipeline.

All building systems are integrated within the central building control system, to enable centralized control of all systems and equipment. The main part of the system is located on the 2nd basement level of wing B. Significantly, all control centers have their own primary information focuses, in the interest of maximizing safety. Currently, the central building control system for the new chemistry facility has as many data points as all of the Justus Liebig University's older facilities combined.
