OZEANEUM, Stralsund, Germany

During the design phase an optimized energy and climate concept was developed for the Oceanographic Museum in Stralsund. The museum exhibits different aquariums, flora and fauna of both, the North and Baltic Sea. Due to the technically complex aquarium equipment and the associated high energy consumption for the processing, distribution and circulation of water, the energy and climate concept focuses on efficient and optimized technology and power generation. A power supply based on a cogeneration system proved to be the best option. Compared to conventional technology with compression refrigeration and gas boiler the chosen supply concept of CHP combined with absorption chillers reduces the CO2 emissions by approx. 2,600 t CO2 / year. Cooling works on two different temperature levels: for cryogenic tanks at 0°C and for the high-temperature tank at 6°C which enables the chillers to run energetically optimized. Sea water is used for heat rejection of the absorption chillers. In shoulder seasons the aquarium areas are ventilated naturally via openings in the North Sea and Baltic Section. For the also naturally ventilated entrance area a radiant floor system is used for heating and cooling . In addition to the radiant floor system a façade heating system was implemented in the foyer, so in case of events this space can be comfortably conditioned.
