First climate-neutral cooling and heating concept in Hamburg's HafenCity!
The new PREVIER prevention center is opening in Hamburg's HafenCity, which uses climate-neutral heating and cooling supplies.
First climate-neutral cooling and heating concept in Hamburg's HafenCity!
An exciting innovation in building technology has been completed in Hamburg's HafenCity: For the first time, a building has been connected to a combined heating and cooling concept. The building in question is the new “Previer” training and prevention center of the BGW and VBG, which not only aims to provide modern work but also make a contribution to sustainability. The center is already a real eye-catcher, with a height of 60 meters and space for around 180 employees. Up to 50,000 guests are expected to be welcomed here every year for seminars and events, and there is also an integrated hotel for seminar participants.
Particular attention is paid to the energy supply of the Previer. Thanks to a cooperation with Enercity Contracting, climate-neutral heat and sustainable cooling are provided. The heat supply is based on the almost CO₂-free waste heat from the multi-metal producer Aurubis. This innovative solution is not only valued as a technical improvement for HafenCity, but is also of great importance in view of increasing heat periods.
Sustainable cooling supply
The heart of the cold supply is a modern absorption refrigeration system that is able to convert district heating into cold. This system requires significantly less energy compared to conventional compression refrigeration systems, which reduces electricity requirements by at least 50%. Around 80% of the cooling comes from industrial waste heat and free cooling, while the remaining 20% is covered by a compression refrigeration system. According to information from Baulinks, the “Hummel” type absorption refrigeration machine achieves a connected cooling capacity of 941 kW and is expected to cover a cooling requirement of 480 MWh per year. A consumption of 483 MWh of district heating is expected for cooling.
The technical equipment and energy concept of the Previer are groundbreaking for future construction projects in HafenCity. Stadt & Werk also reported that the idea of using industrial waste heat to provide climate-neutral heating and cooling will also be implemented in other projects in the future.
In times when climatic changes are becoming increasingly important, the new construction of the prevention center in HafenCity shows that it is possible to combine innovative technical solutions with environmental awareness. This not only creates a modern and attractive working environment, but also an important step towards sustainability and resource conservation - and this is important today more than ever!
