Photovoltaic system on the roof of the existing building of the Heidenheim Cooperative University of Applied Science

STRABAG PFS planned and installed the PV system with subsidiary HUMMEL Systemhaus GmbH

Frankfurt, 3 March 2026
Vermögen und Bau Baden-Württemberg has put into operation a new photovoltaic system on the roof of the Baden-Württemberg Cooperative University of Applied Science in Heidenheim, taking another step towards climate neutrality, security of supply and long-term energy price stability. Vermögen und Bau Baden-Württemberg, Schwäbisch Gmünd office, commissioned STRABAG Property and Facility Services (STRABAG PFS) with the installation of the system, which was planned, constructed and put into operation in collaboration with its subsidiary HUMMEL Systemhaus GmbH. The scope of services also included the planning and installation of an approved fall protection system on the roof.

The new system, with a generator area of over 800 square metres, covers around 20 percent of the annual energy requirements of the existing building of the Cooperative University of Applied Science (Black Cube). With an installed capacity of 184.5 kWp, the system will generate around 186,438 kWh/year of renewable electricity in future. The new photovoltaic system consists of 410 modules, each with a generator area of two square metres. The university uses the electricity generated itself. Surpluses are fed into the public grid.

‘Now all the roofs of the Cooperative University of Applied Science in Heidenheim are equipped with PV systems. I am very pleased that this brings us another step closer to the goal of a climate-neutral state administration. Generating electricity on roofs is not only ecological, but also makes economic sense,’ says Dr Stefan Horrer, head of the responsible office in Schwäbisch Gmünd for property and construction. He adds that in the coming years, all roofs of public authorities and buildings belonging to the federal state will be equipped with PV systems. The only prerequisite is that this is possible in terms of monument protection and statics and makes sense in terms of solar radiation (no shading).

In July 2025, the Schwäbisch Gmünd office commissioned STRABAG PFS to carry out the work to install the PV system. Construction work began in early October and the system was put into operation in early January 2026. DH Heidenheim has been using 100 per cent green electricity from renewable energies since 2022.
