The real estate sector’s transition to sustainability demands fundamental changes in how properties are developed, managed and maintained. For instance, landlords are increasingly investing in rooftop solar as it offers significant carbon reductions, optimised use of otherwise wasted space, and attractive financial returns, with an estimated return on investment of around 19% and net savings of up to £ 535,000 over a 25-year period. Tenants benefit from lower-cost green energy, while landlords enjoy the added benefit of increased property value.
