An Innovative IKEA Approach to Sustainable Home Renovation

Chapter 1: The Climate Challenge
In line with the Paris climate agreement, global efforts are underway to limit the rise in temperatures to a maximum of 1.5 degrees Celsius. The European Union has set an ambitious goal of achieving climate neutrality by 2050. While traditional culprits like fossil fuel combustion contribute significantly to global warming, buildings in urban areas also play a crucial role in carbon emissions.
A Danish architecture firm is stepping up to tackle this issue by developing simple-to-install kits designed to enhance the energy efficiency of existing homes. If implemented globally, these kits could substantially reduce the climate impact of buildings everywhere.
According to statistics, residential and commercial structures account for over 40% of total energy consumption and contribute more than 30% of carbon dioxide emissions in the United States. This is determined by evaluating two key elements: operational carbon emissions, which arise from daily activities such as heating and cooling, and embodied carbon, which is associated with the materials and construction processes involved in building.
The total energy consumption of a building can be calculated through these two factors, known as the "energy intensity of the built environment." The World Green Building Council indicates that to meet climate objectives, a 30% improvement in energy intensity per square meter of buildings is necessary by 2030. Despite some progress, the pace is insufficient to keep up with construction rates. If measures are not taken soon, CO2 emissions from buildings are predicted to double.
However, the larger issue remains: while new buildings benefit from advanced materials and construction techniques, a significant portion of the housing expected to exist in 2050 has already been built.
How can we enhance the emissions profile of these existing structures?
Section 1.1: A New Approach to Renovation
Henning Larsen, a Danish architecture firm, has joined forces with several organizations to create a strategic initiative called REBUS (Renovating Buildings Sustainably). Their mission is to develop and test prefabricated kits aimed at renovating older housing stock to improve energy efficiency. Their initial focus is on social housing constructed in Denmark during the 1960s and 1970s.
The team has set two primary objectives: to renovate this specific type of housing with lower emissions and to do so with minimal disruption to residents. They have achieved this through a prefabricated panel system that resembles an IKEA-style flat-packed facade. This system can be added directly to existing buildings, enhancing insulation and aesthetics simultaneously.
By employing a straightforward bracket system, the panels can be installed while residents continue to live in their homes, minimizing any disruption.
Section 1.2: Customization and Impact
The ease of installation allows residents and property owners to take an active role in the renovation process. Henning Larsen has developed a versatile catalog of options, enabling tenants to select from a variety of sustainable materials and styles for features like windows and balconies. This flexibility ensures that the prefab kits can cater to the unique needs of each building and its inhabitants.
For instance, if a room lacks natural light, residents can opt for a bay window to create a cozy reading nook. Alternatively, those facing ventilation issues can choose larger windows to improve airflow.
According to Henning Larsen, these renovations could lead to a significant enhancement in building performance: “Buildings will consume 50% less energy, with the renovation process utilizing 30% fewer resources and achieving a 20% increase in productivity.”
Despite initial delays due to the Covid-19 pandemic, the team anticipates starting their first project later this year in a housing development in Copenhagen. The scalability and adaptability of this system could open up numerous opportunities for further testing and implementation, provided the first phase is successful. However, the team recognizes the challenges ahead, as various factors—design, materials, construction, environmental impact, and maintenance—will need careful coordination.

The first video titled "Self-Built Tiny House Tour - Sustainable Living | IKEA Hacks & Minimalist Design Ideas" showcases innovative approaches to sustainable living through DIY projects and smart design solutions.
The second video, "30 IKEA Products & Furniture For Small Spaces (Tiny Homes, Studio, Apartments)," highlights space-saving furniture options that can make small living areas more functional and stylish.
While there are various facade cladding systems currently available, most are designed for new constructions. The REBUS initiative stands out as one of the first to focus on reducing the carbon footprint of existing buildings. This innovative, human-centered design approach promises efficient renovations that enhance both building performance and aesthetics without displacing tenants, embodying the essence of flat-packed design done right.
