Ripple Residence: Denmark’s lowest-carbon residential building

Nrep’s Ripple Residence is a residential development in Copenhagen’s Nordhavn district that explores the commercial viability of low-carbon construction. The project features timber as the primary building material, targeted use of upcycled components, and an integrated energy system combining geothermal, solar, and smart controls. It achieves embodied emissions of 250 kgCO₂e/m² and operational emissions in line with CRREM pathways until 2050. Supported by DGNB certifications and green financing, the project shows that low-carbon housing can align with evolving regulatory requirements while remaining commercially competitive.
