Environmental performance A 24-hour lifestyle street will act as the central spine to the development


project to push the boundaries and encompass new technology.” He cites the smoke extraction and


control system for the three-storey mall by way of example. The system has been designed so that the space can be purged with outside air at night to help cool the building in summer, saving an addition two to three per cent of energy. The development is fire engineered utilising fire consultants, JGA, and the building codes have been challenged, for example with smoke control to the malls and northern and central arcades. CFD (Computational Fluid Dynamics) analysis was used extensively, followed by presentations to Newham and London Fire Brigade during the approvals process. A


final report was submitted after extensive consultation. The smoke control strategic reports have been approved and are being incorporated into the final detailed design. The open and frank review process


established with Newham has worked well, says Whitmore, and the recent handover of the shell and core works to John Lewis Partnership, Marks & Spencer and Waitrose, on time is another major milestone for the project. The clock’s still ticking with only nine months until Europe’s largest urban shopping centre opens for business but when the scale of the Games legacy may yet be thrown into doubt, the scope and impact of the retail gateway to London’s East End is beyond question.


• The building’s energy performance will achieve an improvement of at least 45 per cent against 2006 Part L2 when the use of the CCHP is taken into account


• The rainwater harvesting system saves water consumption by just under 8 million litres a year; which will be utilised for public toilet flushing. This would achieve more than 60-70 per cent of that demand, while BREEAM only requires 50 per cent


• All public toilets are fitted with dual flush sensors and have reduced flushing capacities


• The CCHP that delivers chilled water and heating includes a biofuel boiler that will deliver a minimum 2 per cent from renewable sources. The option of providing additional PV technology to some of the roofs is being reviewed


• Air supply and extract system for mall and retail units are linked allowing energy recovery from both heating and cooling


• A centralised sprinkler tank installation serves all retail and non- retail buildings resulting in a latent saving of up to 0.75 million litres of mains water


Westfield will connect Stratford Regional station and Stratford International 14 bflmagazine.co.uk


• A considerable number of roofs have been designated brown, green extensive or green semi-intensive, with important potential biodiversity and amenity benefits.
