The Practice was appointed to undertake an energy audit of the 1438 front quad at All Souls College, and to propose options for reducing energy consumption and carbon emissions from this medieval Grade I listed building.

Arranged in a traditional collegiate style with individual staircases giving access to Fellows’ accommodation, the building has a high thermal mass on the lower floors but a low thermal mass within attic accommodation.

This combination of part stone and part timber posed a particular challenge to improving energy performance.  Through our interventions a 40% reduction in energy use was achieved.
