Energy saving strategy
The energy strategy includes the local public requirements of ecological building, the supply situation at campus north and the demands in reference to sustainable building.
In particular it is realized by:
– no use of sanitary facilities below the tailback level (elimination of pumps), use of water saving fittings and flushing according to state-ofthe- art technology, high standard of water hygiene by minimal amount of heat reservoir
– rainwater drainage with slow down drain by tailback in intensive landscaped roof areas into near-natural trough-trench drainage systems
– reduce of need for thermal heat by a compact thermal envelope according to passive house standard and porch, heat output saving in buffer storage (with regular use of the sports hall in summer months the involvement of solar heat is possible)
– reduce of heat and ventilation output by use of high efficient CO2, temperature and moisture regulated ventilation system with series connection of air consumption for shower rooms and a heat recovery of 85 %
– limitation of heat load in summer by efficient natural ventilation of the triple-sized sports hall, per-cooling of external air of the ventilation regulated areas by geothermal collectors
– efficient ventilation and glare-free lighting by energetic optimized arrangement of motor-driven window opening with external shading including light control elements
– daylight and presence-depending light regulation, control and alert in case of departure from normal demand of energy and water consumption with visualization in foyer
In case of an interior finishing of the triple-sized sports hall with grandstands and with it ventilation and air conditioning a passive house standard can be achieved.
The research sports hall of Humboldt University (HU) Berlin is situated in the core of the historical monument ensemble Campus North in Berlin. The surrounding historical monuments influenced the height and appearance of the new building. This influence and the shape of the site created the idea of the clear and definite differentiation of glass – concrete – metal along the height and the design and arrangement of the building’s mass. Accordant to a highly frequented university use the research sports hall is completely built with materials, which doesn’t need much use of rehabilitation or refurbishment.
Glass and exposed concrete characterize the outward appearance and interior public areas. By applying high-efficient ventilation and heating technology, 20cm mineral heat insulation, triple glazing and a photovoltaic system on the roof minimize the energy demand to passive house standard and feed surplus electricity in the public electricity network. An extensive
landscaped roof and a drainage by a large filter drain system completely repress the rainwater and support the micro climate. The foyer directly connect all areas. From outside the visitor is already able to find out the functional composition of the building. The foyer goes from the lower foyer up to the first floor by voids. The hole building can be used by disabled and visually impaired people.
