Five-to-ten years ago, retail heads of terms would typically include just a small section on sustainability. Today, sustainability requirements feature prominently in leasing agreements and play a vital role in the sector’s drive to net zero.
One of the key sustainability challenges facing developers, given the massive oversupply of retail spaces in the UK, is whether to demolish and rebuild ageing assets, or repurpose and reimagine them. Rebuilding provides the opportunity to leverage new green methods and materials, such as timbers frames, renewable energy generation and landscaping. But is it right that these assets, some of which aren’t even 40 years old, should be swept away and replaced? Is it right that all the embodied carbon in these structures will have had such a relatively short life?
Often, said Charlie Royle, Executive Director at AEW UK Investment, “there’s going to be a trade-off between keeping that embedded carbon [in the building] versus the social benefits of completely repositioning something.” Some buildings, explained Royle, “we’ll have to knock down because we can’t reposition them; the floorplates are too deep…the structure doesn’t work.” But on other sites “we’re working extremely hard to keep as much of the fabric of the building as possible.”
Participants agreed it’s too early to tell whether occupier demand will be driven by repurposed assets or new green buildings. Where possible, said Royle, the best approach is “keeping [some] of what you’ve got, and then building new to improve the retained element of it”. In this way, by balancing rebuild and repurpose, developers can minimise environmental impacts while maximising the social benefits of asset enhancement.
