A collection of buildings
The hospital is located on the outskirts of Deventer, near the village of Schalkhaar. Based on the vision on the area, the characteristic high/low location, the historical details and the specific soil structure were used. At the north side, the hospital reaches with its fingers into the landscape that has been kept intact as much as possible as a man-made landscape; fields and boggy pastures were preserved. The building expresses healthcare’s flexibility and capacity to change. It presents itself as a collection of buildings with their own functions, rather than as a massive building.
Care concept
Point of departure was the so-called four streams model. This model is based on the difference in treatment between patients that require acute, urgent, elective or chronic care. Specific organizations were formed and routes were set up in the building for these types of care, also with a separate entrance, where necessary, for instance for acute care. Functions that are not bound to patients, were located around them, for instance, in the basement and on the third floor.
Flexibility
The building has a flexible construction and anticipates changes in healthcare. The building can be adapted to changing needs in relation to space. At the front, the outpatient clinic radiates flexibility. The architectural structure consists of round columns, steel beams, detachable panels in the façade and internal walls that are easy to remove. Both size and arrangement are relatively easily adapted to other requirements. The central building contains the harder hospital functions such as operating rooms, intensive care and examination/treatment areas. Internal flexibility was obtained by integrating moveable functions such as consultation, work and storage rooms on strategic locations. In the future, they can be moved to the office layer or basement, in order to make room for additional examination or treatment rooms.
Integral design
Sustainability is an integral part of the architectural and installation technical design. Point of departure is the ‘trias energetica’. Firstly, the thermal shell should offer optimum insulation. Secondly, the installations fitted in the building should be as energy efficient as possible. And finally, as many alternative energy sources should be used as possible. In this way, fossil fuels are used as little as possible. The integral design results in a remarkably low energy performance coefficient of 0.67. The environmental index for buildings according to the Greencalc method reaches a high score of 212.
European demonstration project
In the project, many measures were taken for the benefit of sustainability: 98% of the permanent measures and 85% of the variable measures from the national package for sustainable building. As a result, the Deventer hospital is a demonstration project for sustainable decision making. In the field of energy, it is a European demonstration project of the European Commission.
