Technology meets sustainability

The soon-to-be tallest building in Hamburg will not only stand out in the urban landscape, it will also stand as a beacon of sustainability.

A new stream of energy

A building emits greenhouse gases throughout its life cycle. Three quarters of those emissions are caused during its operation. Heating, cooling and power consumption are the main sources.

Thanks to its smart energy concept, the Elbtower will be practically carbon-neutral. The Elbtower’s heating will be supplied by wastewater heat, district heating and waste heat from various production systems.

Smart energy management

Energy flows are networked to derive synergies from the generation of heating and cooling, and the residual energy is then stored.

100% green electricity

The Elbtower purchases power for all tenants from exclusively renewable sources.

District heating

The hotel and restaurants draw on district heating all year round. It comes from a nearby industrial facility that generates hot water.

Cooling

The cooling tower in the crown uses natural ambient air to cool the entire building.

Heat pumps

Electric heat pumps raise pipe temperatures in winter. Chillers lower the temperature in summer.

Wastewater heat

Wastewater heat is used for air conditioning: In summer, surplus heat is extracted, in winter, additional heat is provided.

Green building

Construction is a source of CO₂ emissions. At least one fifth of these are caused by the manufacturing of building materials.

In building the Elbtower, priority is given to components and materials that have a small carbon footprint.

RECYCLED AND ECO-FRIENDLY MATERIALS

The foundation slab – four meters thick in parts – and the pile foundations are made from recycled concrete.

The materials chosen for the interior and finishing all have particularly low emissions.

Mobility shift

The Elbtower is part of an ambitious smart mobility strategy for the eastern section of HafenCity. The project pursues sustainable structures and mobility options.

The Elbtower is directly linked to the motorway network and the public transport network. Subway and local rail stations are right outside the door.

The Elbtower has a spacious multi-storey car park with contemporary features. It isn’t just for cars; it caters for bicycles too. And it even has chargers for electric bikes and a pick-up zone for bike sharing.
