As the architecture, engineering, and construction industry begins to explore sustainable and green materials to construct carbon-neutral buildings, what are we to do with the underperforming homes and offices already built and their continuous carbon footprint?
REBUS is a strategic partnership that answers that question: renovating the existing housing stock is by far the least carbon-intensive construction solution available. Post-renovation, buildings will consume 50% less energy, with the renovation process using 30% fewer resources and yielding a 20% higher productivity.
These ambitious goals foster a unique collaboration from all parts of the industry’s value chain, as sustainable building renovations are not only a valuable market for the industry but also increase the quality of life for those who call these spaces home.
The team at Henning Larsen has designed a versatile catalogue of facade renovation options, led by the principals of shortening construction time, using sustainable materials, and limiting nuisances for residents. The result is an adaptable and scalable facade panel that can be quickly mounted onto the building and even on top of the existing facade.
The facade catalogue of modular window and balcony openings enables personal customization— en masse. No matter if residents choose a generous window opening, French balcony, or outdoor balcony, all improve quality of light, ventilation, acoustics, and energy performance.
The facade catalogue reimagines the renovation process, creating smarter, flexible, and more resilient adaptations that considers the entire building lifespan, from cradle to disassembly and back to cradle.
As a point of departure, REBUS focuses on the social housing blocks built during the 1960s and 1970s— the largest amount of square meters ever built in Denmark. Due to the abundance of this housing typology, the potential for improving quality of life and energy performance is immense.
For Denmark to reach its ambitious climate goals, the 12.5 million m2 of public housing built between 1960-1979 must be rapidly renovated. By prioritizing residents' input, we are able to increase not only utility, but architectural quality and quality of life.
This human-centered approach has been able to produce both a product and a process; providing a template for cost-effective facade renovations that can be facilitated faster than the traditional approach and completed without having to rehouse tenants. The cost savings highlight REBUS as an economical and sustainable option for developers and municipalities.
The future impact of the REBUS project encompasses the highlighted UN Sustainable Development Goals.
