Case Study Education - Freiburg Student union

The student union (Studentenwerk) has upgraded its dormitories to an electronic PegaSys offline access control system from NORMBAU. The new door terminals, which work with contactless, readable identity cards, reduce the workload of the technical personnel and provide a high level of flexibi-lity to students with access permission.
Freiburg, in the southwest of the country, is unquestionably one of the most popular university towns in Germany. The Studentenwerk Freiburg (SWFR) makes a valuable contribution to education there. As a public institution, the SWFR and its 350 employees are responsible for the social support of more than 40,000 students.

At its diverse locations, the SWFR operates dormitories with a total capacity of 3,800 persons, from individual apartments to large group units.

The challenge

"As the student union (Studentenwerk) we must negotiate a path between social pricing and generating enough revenue to cover our costs. To accomplish this goal, we follow a clearly formulated mission statement: 'Quality at a reasonable price'", explains Thomas Wehrle, Executive Architectural at the SWFR for the Residential Department.

In the past, SWFR secured all entrances and apartment doors using purely mechanical profile cylinder locking systems. In addition to getting rather old, the system proved to be increasingly cost-inefficient for operation and maintenance. The costs associated with the replacement of keys and cylinders were high. A fast, need-based adaptation of permissions was not possible in this rigid locking concept.

The solution

WFR chose the intelligent PegaSys System 200 from NORMBAU, which works with contactless MIFARE credentials and consists of centralised software for control and evaluation, a read/write station for issuing and updating the user credentials, high-quality locking terminals for all outer and apartment doors as well as wall reading stations at the house entrances. All residents and employees who are authorised access are recorded in the system and permissions can also be asig-ned on the basis of time and date, facilitating, for instance, the work of external visitors.

The hardware was also developed by NORMBAU to provide customers with a cost-efficient solution for optimal building security with excellent functionality, flexibility, control and safety. The electronic door terminals with their robust stainless steel housings comply with protection class IP 65 and are certified according to DIN 18273.

In the meantime, the PegaSys system has been installed at six SWFR dormitories in Freiburg and Offenburg and manages approximately one thousand students there, with more being added over time.

For the technical personnel, the conversion to electronic access control has meant a continual simplification of their work each and every day. The "key diversity" of the past no longer exists, the loss of a credential can be processed much more easily and thanks to the contactless readable identity cards, the spatially and temporally restricted permissions for workers or other persons can be configured much more quickly and efficiently. Furthermore, explains Thomas Wehrle, the overall overview of the system is significantly better than before: Who has access to which rooms of the building? Which identity cards have already had to be replaced? Where have unauthorised attempts at entrance occurred frequently?

"We have it all", emphasises Thomas Wehrle: "We will continue to use the PegaSys system in the upcoming new buildings and invest further in this comprehensive security system."
