What can Cambridge's historic buildings teach us about the benefits and challenges of reusing heritage buildings?
Key themes: Built Heritage, Adaptation, Environmental Sustainability, Creative Reuse
In Europe, 75% of our building stock is old and inefficient and Cambridge city centre is a reflection of this on a highly concentrated scale. Whilst narrative often focusses on the requirements and standards for new buildings in a future net zero carbon world, current buildings, including their operation, account for nearly a third of total global energy consumption and c.15% of direct CO2 emissions.
Designing-in new technology is deemed easier than retrofit, so this tour focusses on two city centre buildings, both historic, one listed. At Entopia, the Cambridge Institute of Sustainability Leadership (CISL) aimed for, and delivered, a comprehensive retrofit programme. Its lessons of success can be explored and shared. The Guildhall, meanwhile, is the City Council’s central office, and a Grade II listed building. Despite efforts to improve its environmental credentials to date, it remains both economically and environmentally expensive for the Council to maintain, while its design does not encourage the social collaboration central to contemporary working styles. The challenge is to develop a viable programme to redesign and retrofit the building to provide a fit for purpose staff office and civic provision, alongside the potential to share space and derive income.
