The National Center for Tumor Diseases (NCT), established in 2003, is a joint project of the German Cancer Research Center (DKFZ), Heidelberg University Hospital (Universitätsklinikum Heidelberg), Thoraxklinik (hospital for thoracic diseases) at Heidelberg University Hospital and German Cancer Aid (Deutsche Krebshilfe). The NCT's key objectives include improving standards of hospital care for cancer patients by applying an interdisciplinary range of diagnostic and treatment resources.

The NCT's special structure – with its links between research and patient care – is designed to facilitate faster, more efficient transfer of innovative approaches, emerging via basic research, to applications in the areas of cancer diagnosis, cancer therapy and prevention. The key objective for the cooperation is to achieve the greatest possible benefits for all parties concerned.

The NCT building, with gross floor space of about 13,200 m², is divided into a laboratory area for research and a clinical area for patient care. All supply and disposal requirements are met via the clinic's existing infrastructure.

As part of planning, ZWP carried out thermal simulations for the entire building, in order to check the effectiveness of planned building-component activations. Room conditioning in the atrium, which is naturally ventilated, was simulated and optimized via a flow simulation.

The ventilation and partial air conditioning systems for the structure have airflow rates of 84,000 m³/h for both intake and outflow. Electrical power is provided via a connection to the clinic's 10kV ring, as well as via two 630 kVA transformers. In addition, safety-relevant systems have been connected to a 400 kVA emergency power system. For telephone and data services, a structured voice/data network, with some 1,800 ports, is in place. Building services are controlled via a network of modular, programmable, digital automation stations with links to the hospital's control level. Rainwater that falls onto the facility premises is collected and guided to a French drain for infiltration.
