FEASIBILITY OPTIONS ECD Architects provided two options for the refurbishment of Wilmcote House: 1. The first option being the installation of a communal heating system with insulation to the existing envelope in accordance with UK building regulations Part L2B. 2. The second option was to super-insulate externally and simplify the existing envelope to the EnerPHit standard such that a new heating system might not be required. In this option ventilation would be provided by individual high efficiency MVHR units installed in all flats with triple glazed windows throughout.
