TENDER DESCRIPTION

The demonstration centre for sector coupling is designed as a research building, combining laboratory and office space. The building plot is part of the research campus at Schleusengraben. Under building law, the zoning plan (B-Plan) Bergedorf 104 /Curslack 19 is binding. The 3-storey building is arranged gable-end to the road between Am Schleusengraben and Schleusengraben, on the southern boundary of the plot. In the northern part of the plot, the parking spaces are located. The heating and cooling technical systems include heat and cold generation, heat and cold distribution, and the space heating and cooling areas for the demonstration centre for sector coupling. The heat and cold supply is provided by three reversible air-to-water heat pumps (refrigeration units) in rooftop installation, with a heating output of approx. 30 kW and a cooling output of approx. 45 kW per unit, supplemented by buffer tanks, an electric heating unit for peak load coverage, and a hydraulically balanced pipe distribution network made of copper and steel. The conditioning of the spaces is provided via ceiling radiant panels, underfloor heating, and air recirculation coolers/heaters (2- and 4-pipe…
