The refurbishment of Ten Gresham seeks to minimise environmental impact while creating a more efficient building for the next phase of its life cycle.
All electric
The renovation will improve Ten Gresham’s operational energy use by 46% and will result in a 72% reduction in operational carbon over the building’s service life.
Water
Ten Gresham will use 55% less potable water than a typical building by installing low flow plumbing and utilising rainwater and greywater. This saves an average of 18 litres per occupant per day, the equivalent of 45 swimming pools every year.
Embodied carbon
The RIBA 2030 target sets ambitious goals for minimizing embodied carbon throughout a building’s lifecycle: from extraction and manufacturing to construction and disposal. Ten Gresham is set to surpass the RIBA target for new offices by 67%.
Waste
50-75% of waste generated by the refurbishment will be reused or sent back to manufacturers for recycling. Furniture and equipment is being donated to not-for-profits like charities, schools and NHS trusts via Collecteco.
Health & wellbeing
Targeting WELL Core Platinum, the design aims to add biophilia throughout the building, improve acoustics and provide high quality air, reducing stress and improving wellbeing. Active travel is encouraged with the provision of 480 cycle spaces and lockers.
Biodiversity
A net gain in biodiversity will result from both the new roof, allowing the creation of habitat supporting vital pollinators and other invertebrates, and flower-rich perennial planting at street level, increasing the building’s Urban Greening Factor from 0% to 12%.
