The research institute for aquaculture deployed in Scheveningen as a strategic element in the transition from fishing port to haven of knowledge.The House of the Blue Revolution presents a strategy that picks up on changes in the fishing port in Scheveningen. It shows how this industrial area can be upgraded at different scales, respecting its distinctive character and the history at that site. The research institute for aquaculture has a key role to play in this. It is an incubator where networks of research, market players, politics and creativity in the field of aquaculture intersect.An important stepping-off point for the design is that the area is to be transformed strategically in phases, with the aquaculture institute serving as an incubator. In changing the purpose of the Scheveningen port from production to knowledge, it can develop into one of the Netherlands' first fully eco-effective business zones and a magnet for international investors in future technologies.Visafslagweg is a special road for Scheveningen, not because of its architecture but for the air it exudes of tradition, age-old skills and fisheries. This project therefore proceeds not from demolishing the old industrial fabric in exchange for a new one but rather from designing an increment that can meet a need within the process of transformation. These buildings can then be fleshed out at the required speed.The new structure is draped as a subsequent layer over the port and its received activities leaving few if any scars. The project is a rendition of several socioeconomic graphs of change: the rise of aquaculture as against the decline of the fisheries, economic cycles and the emergence of knowledge technology. Location, building and programme need to be capable of accommodating these changes without compromising the quality of the place and its significance for The Hague.The interaction between the public and the world of science is fuelled by adding a public plaza and deck where the development of the old fishing industry into cutting-edge aquaculture is put on show. The building has three categories of person using it: researchers, professional visitors and the general public. For the researchers, the centre is their daily place of work, divided into a wet programme (breeding pools) and a dry programme (laboratories and workplaces). Among the professional visitors are fish breeders and producers, policymakers and financers. For them the building is a marketplace for knowledge.The general public is just as welcome in the research centre. For the casual passer-by the plaza and deck are most valued as a place to linger. For the swelling group of socially enlightened, environmentally aware and knowledge-seeking citizens, this place is a billboard for research & knowledge and sustainable economics. They can make use of the visitor centre, view the exhibitions in the 'fish forum' and take guided tours through the institute. There is a fish bar on the deck open to all users where they can sample the most recently bred species of fish.The building housing the research centre is conceived of as an assemblage of climatological conditions. The inner and outer leaves of the facade are in effect pulled apart to generate an in-between climate that can act as a buffer to temper extreme conditions. By using locally conditioned spaces the energy consumption for heating and cooling is limited to the spaces that really need one or the other. Depending on the circumstances the surplus heat or cold is stored in the ground or reused directly in accordance with the principle of concrete core activation. This system can also be applied to night cooling whereby the entire building is 'opened up' and can fill itself by suction with healthy cool sea air so that in summer a pleasant indoor climate can be obtained within one day.
