The new HELIOS Albert-Schweitzer-Klinik Northeim combines medical excellence with very high standards of service and amenities for patients. In 2009, ZWP Ingenieur-AG was commissioned to develop a special energy concept, plan the technical building services, and monitor their proper construction and implementation. The new facility includes more than 300 planned beds, a 1,200 m² state-of-the-art surgical wing with six operating theaters, and a 24-bed intensive care unit.
The new building is heated by a combined heat and power (CHP) plant with 210 kW thermal 140 kW electrical output for base load supply and two gas boilers rated at 670 kW each. The CHP plant covers about one third of the facility‘s annual heating energy requirements. All electricity generated is used entirely on site.
Ventilation for the surgical and functional areas as well as patient rooms is provided by seven central ventilation systems with a total volumetric airflow of 110,000 m³/h. Heat recovery is ensured via a central, tripartite combined-circulation system with adiabatic exhaust-air humidification.
The control and regulation of the technical systems is managed via five information centers with approximately 4,000 physical data points using BACnet technology. A transformer station with two 630 kVA transformers has been installed in the building. Backup power is provided by an emergency generator with an output of 510 kVA.
A service-neutral network for data and communications services with around 1,400 ports was installed. In total, approximately 300 km of cables and wiring were laid for high-voltage systems, telecommunications and IT installations, and building automation.
