Danfoss completes Danfoss House construction in Denmark

Danfoss has completed construction of the Danfoss House in Sønderborg, Denmark—a multi-residential building that doubles as a live-in testing facility for sustainable building technologies. The project is the world’s only brick-and-concrete residential structure to earn DGNB Platinum certification, the highest level under the German Sustainable Building Council’s (DGNB) standard.

Designed as a demonstration of decarbonised multifamily housing, the building integrates a wide range of Danfoss energy solutions. These include both centralised and decentralised heating systems for comparative testing, floor cooling, diffuse ventilation with cooling, and a smart home setup that ensures temperature stability through active monitoring. Ten 100-meter-deep (328 ft) geothermal boreholes support year-round groundwater-based heating and cooling.

The project also received the DGNB Heart for promoting well-being and indoor climate, and the DGNB Diamond for design and architectural excellence. Locally, it was named the most successful and beautiful new building in Sønderborg Municipality by the City and Environment department.
