Building and infrastructure are responsible for approximately 40% of the global CO2 emissions. As architects, designers and promoters, we need to rethink the way we design buildings. To ensure they use less material, to make them more efficient in term of material quantities per effective m2/built, and to increase their life cycle.

To do so, we have to consider building flexibility. Integrity issues are not the first cause of building demolition. Too often, buildings in good condition are torn down because their interior layout or their general organization no longer meets market needs. How can we ensure that the buildings we design or renovate today can be easily adapted over time to accommodate the needs of different tenants?

Using the right material at the right place can significantly reduce quantity, price and CO2 emissions. The industry has started to decarbonize the production of basic materials. How is this taken into account and what is the impact at the building level?

Finally, designing a building today is also to think about the end of life. As buildings become taller and taller, how will we manage the end of life? How will we manage the deconstruction? And, what will we do with this massive quantity of materials?
