TEARING DOWN THE CARBON FOOTPRINT OF BUILDINGS WITH NEW INTERNATIONAL STANDARD

Contributing nearly 40 % of global CO2 emissions from energy, the building sector has enormous potential to clean up our world. A new International Standard helps the industry do just that by optimizing how buildings are used as well as effectively reusing and recycling their components when their time is finally up.

ISO 20887, Sustainability in buildings and civil engineering works – Design for disassembly and adaptability – Principles, requirements and guidance, helps owners, architects, engineers and any other party involved in the life cycle of a building to improve its sustainability, saving time and resources along the way.

It assists users in two ways: by extending the building’s life through effective adaptability that makes it suitable for another use; and by optimizing its resources at the end of life through effective disassembly, reuse, recycling and disposal of its various materials.

The result is reduced carbon emissions through optimal use of the building, lower costs through longer lifespan and better use of resources, and less waste going into landfill.

Philippe Osset, Chair of the ISO subcommittee that developed the standard, said users get the most benefit from disassembly and adaptability guidance if they consider its integration into the very early stages of the building works project.

“This will help them obtain the full potential value of a building throughout its life cycle, from repairs and refurbishments to the reuse, recycling and appropriate disposal of its components when it is no longer able to be used,” he said.

“What’s more, this approach is exactly what supports the circular economy, thus contributing to a more sustainable world.”

In that sense, the new standard also contributes directly to the United Nation’s Sustainable Development Goal 11 on sustainable cities and communities.
