This low-energy retrofit project sees the sensitive refurbishment and restoration of Florence Boot Hall, one of University of Nottingham’s three ‘heritage halls’. Dating from 1928, the hall had not received a significant fabric upgrade since it was constructed. Mechanical and electrical systems had not been upgraded since the 1990s.
The University’s vision was a fabric-first approach which would deliver a low-energy hall fit for the next 70+ years of student occupation. This approach included levels of insulation and air-tightness which are close to contemporary new-build levels. This was to be delivered whilst respecting the Hall’s heritage status and appearance, having been the brainchild of Florence Boot as the University’s first hall of residence for female students.
The project team developed an approach incorporating a high-tech aerogel insulation lining to the internal face of the external walls, coupled with ASHP driven wet radiator heating which allowed the external appearance of the building to remain unaltered whilst providing significant performance upgrades to the fabric.
Through the careful adaptation of the existing built fabric, alongside the removal of the ‘warden’ role, an increase in ensuite bedroom and shared kitchenette accommodation was created whilst resulting in a net increase in bedroom numbers.
Three Winning Facts:
- Fabric performance close to new-build levels
- UPVC double glazing replaced with triple glazed timber sash windows
- Fully sprinklered
