House 5 from the former premises of the Greisinger hospital will be remodeled as a ward for the neurology department of the emergency hospital. The vast majority of the technical equipment in House 5, including its design, is from pre-unification days. Various local renovations and modifications have been made since 1989. However, there was no general overhaul of the equipment. GTB developed a refurbishment concept for the heating, sanitary, and ventilation technology. The existing systems were included and continued to be used, whenever possible.
