Hear from Dominique Alba, Wiebke Ahues, Aurélien Delchet and Yvan Okotnikoff.
During the webinar, we analysed the topic or flexibility through a multi-angle approach: Planning & construction; ecology & quality of urban life; heritage & future; regeneration & new development; aesthetic, technical & financial considerations; policies & tools,...
Also find below a quick recap of what has been presented and discussed during the webinar:
- reversible in the long term to allow change of use over time (i.e. transform offices to housing). This is key to reduce the need for demolition due to the change of use
- flexible on a daily/weekly basis to allow several uses over the day/week, with a chronotopic approach. It is extremely important to maximize the use of a building and therefore reduce the need for new buildings (see both examples of the Morland project and the Collective for Climate project)
- Need to design the project twice to make sure the two configurations are working
- As your building space must work for two or several purposes, you need to design and build according to the most constraining rules (fire regulations...)
- The key points of reversible design are the ceiling height, configuration of the structural grid and quality of the construction materials (some buildings cannot be transformed because the quality of materials is too scarce, for instance, the poor quality of concrete)
- Because of the three previous points, it is more expensive to build "reversible". However, the building will last longer, so the developers/investors must develop a new way to integrate this consideration in the balance/return on investment of their projects
- Reuse before demolishing
- Use existing materials. Buildings of today are resources for the future (urban mining)
- If new, build flexible
- Use sustainable materials
- Administer used materials, for the future (two ideas discussed: passports for materials and sites to collect and store materials from deconstruction)
