“We need to move beyond measures like offsetting and, instead, move positively towards embracing a circular economy, reuse of materials and structures, and biodiversity net gain.”
To open the discussion, Chris set out the concept of “environmental equilibrium.” Sustainability to him means “keeping the planet in balance and ensuring that the contributions of the built environment don’t take us over a tipping point.” Chris acknowledged the difficulty of this aim, given a globalised supply chain and development model that rarely has enough consideration for maintaining an equilibrium.
Charlie agreed and wanted to extend this thinking, adding that sustainable development “should not just be net zero, but net positive as a minimum.” This, he said, will help the sector “to move beyond measures like offsetting and, instead, move positively towards embracing a circular economy, reuse of materials and structures, and biodiversity net gain.”
Such ambition clearly poses a challenge because the sector is still struggling to hit its net zero targets, and net positive is therefore even further off. Ana was keen to add that “we can’t let ourselves get overwhelmed by the scale of what we need to achieve. That would stop us from doing anything.” Letting “the perfect be the enemy of the good is not helpful, and working on ever more sustainable projects allows us to build green skills and new approaches in the process.”
“It's time to expand the role of the architect – working on a long-term basis with clients to advise them on portfolios and how to decarbonise or reduce their footprints”
“A bespoke space can still be designed using standard elements and materials – allowing for much easier reuse or redesign potential”
When working on new or existing buildings, noted Ana, “the essential point from a sustainability perspective is to ensure that the structures will have the longest possible lifespan to justify the embodied carbon.” This is achieved by ensuring flexibility is at the centre of the design ethos – that “even when a building is tailored to a client’s needs, there is capacity for it to be easily rejigged when those needs evolve, or as a new occupier comes in – without another big carbon input.”
Charlie raised the importance of “standardisation and consistency” to delivering flexible, reusable spaces. Chris agreed, noting that “a bespoke space can still be designed using standard elements and materials – allowing for much easier reuse or redesign potential.” In conversations with clients, Joyce was impressed with how much this is becoming understood, and that “materials and how they are used or disposed of is much more part of the discussion than it has ever been before.”
For many clients, sustainability is now much higher up their agenda. “All the doors we’re pushing are open now,” said Richard, “both the ethical agenda and the fear of stranded assets are driving a change in occupier attitudes.”
“Architects need to be more ambitious, both in our role, and in our approach to sustainability – moving beyond net zero to net positive.”
