Sustainability

• Sustainability strategy developed in

conjunction with sustainability and energy consultants, XCO2 Energy to explore, identify and optimise the environmental and energy performance of the Development

• Starts with basic principles of site layout

and building orientation and responds to constraints including noise and air quality

• In line with the Mayor’s London Plan (2015)

and LBH’s Local Plan (Substantive Version Part 1 - May 2015)

• Expected to reduce regulated CO2 emissions

by 33.9% (when compared to Part L of the Building Regulations (2013) and will meet the London Plan of 35% through carbon offset payment

• Offjce component to achieve a BREEAM New

Construction rating of ‘Excellent’

• Optimised passive design measures to

ensure a fabric-led approach to sustainability including a parametric facade study and solar radiation analysis to inform the design and integration of solar shading elements

The Proposed Development has been designed with a holistic sustainability strategy to deliver a socially and environmentally responsible scheme
