The Diakonie-Klinikum in Schwäbisch Hall is being expanded in two construction phases with several new buildings, while the existing building stock is being renovated, remodelled and functionally integrated into the overall planning. ZWP Ingenieur-AG was responsible for the planning and project supervision of the technical building equipment for the first construction phase from 2013 to 2018. Since 2015, ZWP has also been commissioned with the planning and project supervision for the second construction phase.
The supply and disposal of media is carried out via the hospital's existing infrastructure. As part of the first construction phase, central components of the heating and cooling supply - including the district heating transfer station - were planned and the technical requirements for retrofitting additional cooling generators were created.
The distribution networks taken into account during the planning phase already enable the connection of further construction phases and thus contribute to a secure long-term supply.
A GMP (Good Manufacturing Practice) area, including the associated monitoring system for quality assurance, was planned for the production of medicines. All patient rooms were equipped with a controlled ventilation system in which the supply air is fed directly into the rooms and the exhaust air is discharged via the interior wet room.
A high-performance heat recovery system is used in the circulation system. One heat exchanger is installed in the fresh air intake and another in the exhaust air section. The recovered heat is utilised via a hydraulic module with integrated control to preheat the outside air as required.The system fulfils the requirements of DIN 1946-4 with regard to hygiene and prevents mass transfer between the supply and extract air flows. The heat recovery rate achieved is around 70 % (balanced dry).
