PwC UK, One Embankment Place

London, UK

PwC believes that the experience of this refurbishment project proved the business case for re-use of an old building as well as the associated benefits for employees and the local community.

Tackling the impact of old building stock is one of the major challenges in a transition to a low carbon economy. PwC engaged ChapmanBDSP to develop options that would achieve a minimum BREEAM rating of Excellent, whilst aspiring to ‘outstanding’ status.

Due to the close proximity of the building to multiple businesses, workshops were held with staff and locals to ensure the plan worked for everyone, including issues of noise and timely delivery plan.

New technologies adopted to the scheme include a tri-generation combined cooling, heat and power system. This is fuelled by recycled waste vegetable oil that is collected and refined locally to a new efficiency standard by Uptown Oil and South Bank University.

Chiller beams replace air conditioning and low-power lift braking has been installed, along with eco-friendly carpet tiles and electrical charging points. Open plan spaces and airy atria provide natural light; roof gardens and green walls contribute to the building's ecology; and waterless urinals and low flush toilets reduce water use.

During the work, 95% of materials were sourced responsibly and 96% of construction waste was diverted from landfill. The result is a building with Environmental Performance Certificate A and a BREEAM score of 96.31% – surpassing all others internationally. Today the building emits 40% less carbon than one typical of its size.
