The University of Bristol’s refurbishment of this Grade II Listed Georgian townhouse has received a BREEAM Excellent rating
Report from – Damien Carr
The Listed building includes a Grade II* entrance and a modest 1912 extension to the rear. The 3,000m² constricted site in central Bristol and was bought by the University in the 1959 and converted into offices and teaching spaces.
The refurbishment is to accommodate the University’s growing Law School in 2017, Plans include new tutor and seminar rooms, research suites, a state-of-the-art moot court, a public-facing office for its fast-growing pro-bono clinic.
Being a historic building, material specification was extremely important. Initial work included a historic building assessment, combining this conservation approach with more modern considerations such as security, safety and disability access.
The next step was then to consider air quality and responsible sourcing which allowed materials to be specified and purchased that were low in embedded energy, sourced from environmentally sympathetic suppliers with a limited impact on air.
A pre-demolition audit and historic building survey was undertaken to identify what materials could and should be retained. These included reusing historic fabric such as old chimney flues to route building services, and floors that were structurally sound but not level were retained to avoid waste. In some areas, partitions have been designed to be reusable for future adaptation.
Due to the listing, glazing could not be replaced nor secondary glazed in most spaces. However a thermal comfort assessment was undertaken to optimise the location of radiators in relation to furniture, windows and people’s seating positions to ensure that natural ventilation would work in summer and drafts were not a problem in winter. This was combined with an advanced heating control strategy to optimise heat energy.
