The highly modern office and commercial space in Hamburg’s HafenCity fulfils the highest efficiency standards and has been certified with DGNB-Gold. Three active probes and one heat pump cascade cover the basic load requirement of heating and cooling and thus is ideally utilised to its capacity. Any requirement peaks exceeding this area managed using district heating and compression cooling. Thus, operating costs and capital expenditure are optimised. The technology of the active probe enables groundwater to be pumped only in to one heat exchanger hidden in a borehole before it is refed in the aquifer through the attached coaxial outer pipe. The groundwater does not escape the ground at any point of time and circulates under the floor panels of the building.
