Danfoss Greenpeace Building

Energy efficient air handling, low CO2 emmissions and integrated safety features behind choice of Danfoss.

The new German headquarters will reside in a 45,000 m² office complex that opens this summer in Hamburg Harbour City. Designed and built to achieve the highest energy efficiency levels, the building uses renewable energy sources for heating, cooling and electricity.

Energy efficiency and safety
15 VLT® HVAC Drive FC 102 ranging from 7.5 – 22kW are installed in building’s air handling units to speed control fans. The Danfoss drives were chosen due to their energy efficiency, ability to control permanent magnet motors and the built-in software functions: flying start and fire mode.

Environmental Gold standard
The combination of solar panels, wind turbines and heat pumps will enable the building to comply with the Harbour City’s Gold standard. This means that the building will have a maximum energy consumption of 100 kWh/m² per year, with CO2 emissions of 89 g. per kWh.

About Flying Start and Fire Mode
Flying start is a protective VLT® feature that enables the drive to catch a motor in motion smoothly. Fire mode ensures that the drive keeps e.g. stairwells free of smoke, by ensuring higher air pressure in these areas.
