119 Ebury Street, the UK’s first listed building to achieve BREEAM Outstanding, wins prestigious sustainability award

18/03/2015

The refurbishment of the listed Georgian Terrace, 119 Ebury Street, achieved the highest level of sustainability certification, a BREEAM Outstanding rating. Now, it has received the accolade of a 2015 BREEAM Award too. 

The conversion of the former hotel into three duplex apartments is testament to the feasibility of achieving BREEAM ‘Outstanding’ at design stage in a heritage context and to Grosvenor’s position as a leader in sustainable conservation. Eight Associates acted as BREEAM and energy consultant for the project.

The Development Managers at Grosvenor were committed to achieving the highest possible level of sustainability on the listed residential property from the project’s inception. Eight Associates were appointed pre-planning to advise on the most appropriate BREEAM strategy and the building services design parameters to achieve the required energy demand figures.

BREEAM Domestic Refurbishment is the leading UK sustainability benchmarking system for residential refurbishment. The assessment measures energy and water consumption, the type of materials used, management of waste and the wellbeing of future occupants. The project’s comprehensive sustainability features include greywater recycling and rainwater harvesting, vapour-permeable solid wall insulation, 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 the in-use environmental impact.

Workshops were held between Eight Associates and the M&E engineer Edward Pearce LLP to devise the optimal energy strategy, 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 under the careful supervision of Grangewood Builders’ own eco champion.

Edward Lowes, Eight Associates: “Having a development management team with strong aspirations for optimal levels of sustainability, as well as a capable and enthusiastic design team has been the key to success”.

Emily Hamilton Sustainability Manager for Grosvenor Britain & Ireland: “Ultimately, a building designed and built to BREEAM ‘Outstanding’ will likely have significantly reduced running costs, whilst ensuring the occupants have a healthy and high quality environment in which to live”.
