119 Ebury Street
UK’s first 'BREEAM Outstanding' listed building
Eight Associates acted as the Energy Specialist and BREEAM Accredited Professional for the refurbishment of a listed Georgian terraced property, 119 Ebury Street – the UK’s first listed building to achieve a BREEAM ‘Outstanding’ rating at design stage, for which it received a 2015 BREEAM Award.
The conversion of the former hotel into three duplex apartments is testament to the feasibility of achieving BREEAM ‘Outstanding’ in a heritage context and to Grosvenor’s position as a leader in sustainable conservation.
Eight Associates were appointed pre-planning to create the strategy for achieving the desired BREEAM rating, along with associated targets for energy demand and carbon emissions.
Workshops were held between Eight Associates and the M&E engineer Edward Pearce LLP to devise the optimal design parameters for building fabric and services, which deviated from the agreed planning scheme. Westminster City Council approved the revisions and the strategy is now in the process of being implemented on site.
The project’s comprehensive sustainability features include mechanical ventilation with heat recovery, greywater recycling and rainwater harvesting, vapour-permeable solid wall insulation, vacuum glazing, and photovoltaic and solar thermal energy generation.
Eight Associates also carried out a tenant profiling study in partnership with Grosvenor to establish optimal design features to minimise each apartment’s in-use environmental impact.
