Ripple Residence

Project description

New wooden residential building of approximately 13,200 m² across 6 floors in Copenhagen’s Nordhavn. The construction is a development project where life cycle assessment (LCA) is the guiding parameter. The developer, NREP, aims to reduce CO2 emissions to below 5.0 kg CO2e/m²/year. NREP is a real estate investor committed to creating long-term sustainable solutions in the building industry. For more than a decade, they have supported and invested in projects like Ripple Residence.

Ripple Residence is a climate-ambitious flagship residential project located in Nordhavn, Copenhagen. The project goes beyond best practices for low-CO2 construction in terms of programming (challenging function and CO2 per resident), design (maximal use of biogenic materials), execution (low-emission construction site operation and minimal waste), operation (balancing capacity with consumption), and dismantling (easy disassembly and reuse).

The building is a 6-story wooden structure that will house owner-occupied residences for a total of approximately 500 residents, plus common areas and a few commercial spaces on the ground floor. The project is a development project, which is an acknowledgment that the developer and advisor incorporate into the project’s framework.

PART OF THE 4 TO 1 INITIATIVE - Ripple Residence is part of the ’Housing Construction from 4 to 1 Planet Initiative,’ which aims to inspire and challenge material producers, designers, contractors, and developers. The initiative is supported by Realdania and the Villum Foundation, which have an ambition to reduce the climate footprint from the construction of new homes in Denmark by 75%. As a flagship project, the project will explore and demonstrate how buildings can become CO2 banks, where more CO2 is captured and incorporated from the atmosphere than is emitted.

LCA AS A DESIGN PARAMETER - The project has, from the start, involved ambitious goals for reducing the overall CO2 footprint - therefore, our LCA specialists have developed our own LCA tool, which we have used very early in the process. Our approach provides a clear visualization of the most effective options for reducing CO2 emissions, ensuring focus on the initiatives that will have the greatest impact on the building’s overall climate impact.

This method is integrated throughout the design phase, allowing for continuous optimization of the project’s climate impact and making the most appropriate decisions for the project’s climate footprint.

Our self-developed LCA tool supports a successive approach to LCA analyses, enabling the implementation of a sensitivity analysis for LCA results. This is done by including minimum and maximum values for both quantities and environmental data.

The results from our LCA tool at a given stage will therefore highlight the uncertainty in both quantities and specific material choices. We prioritise that our analyses create a concrete positive effect on the planet - and with the tool, it is possible to calculate other LCA methods parallel to the BR18 method.
