The new Ommelander Hospital Groningen (OZG) will provide care to around 140,000 people from the Northeast Groningen region in the Netherlands. The health care institution is modern, patient-oriented and equipped with a variety of smart and energy-efficient technologies.
Janneke Procee, project coordinator New Build of the OZG: ‘The interests of our patients are paramount, that has always been the basis for the design. However, we needed the right expertise, because we know how to provide good care, but not how to build a new hospital. We selected the experts in the market: Leeuwenkamp Architecten, Deerns, Pieters Bouwtechniek and Tauw. We really wanted to have an entirely new hospital built with the latest technologies.’
Smart, conceptual, energy-efficient
The hospital is equipped with a variety of smart and energy-efficient technologies. For the central energy generation it uses thermal energy storage with compact tanks stored above ground in which cold and heat are stored. Deerns came up with this sustainable concept with short-term buffers, because a conventional ATES system with sources was not possible due to the too high iron content in the water.
Splitting energy supply and redundancy
Another smart solution is the splitting of the energy supply and redundancy in the different parts of the building: the day-time, the ward and the hot floor with operation rooms and intensive care wards. This distribution makes it possible to design customised systems, depending on the nature and functions of the building part. For example, the air conditioning and lighting are automatically switched off in the outpatient clinic and the offices when they are not in use. And redundancy is only provided where backup of the primary process is needed. The result: less complex and more energy-efficient systems that are easier to maintain.
The design team worked in one BIM model this helped to take decisions faster and better control the cohesion between construction, installations and the architectural part.17 January 2018
