Strata, central London’s tallest residential building at 147.9m high and the world’s first tower with integrated wind turbines, is on track for completion next month.
Main contractor Brookfield Construction recently installed the turbines after a successful trial erection at ground level reduced this phase of construction from 18 weeks to six.
“The trial erection allowed the team to check the build methodology,” says Brookfield project director Matthew Hewitt.
The turbines were added to help it achieve the mandatory 10% onsite renewable energy target set by London mayor Boris Johnson and the Greater London Authority.
The three, five-bladed, 9m diameter wind turbines are rated at 19kW each and are expected to produce 50MWh of electricity per year. This will provide approximately 8% of Strata SE1’s estimated energy consumption.
Independent analysis by Integrated Environmental Solutions (IES) has found that Strata should achieve a 73.5% reduction in CO2 emissions relative to the Building Regulations benchmark.
Demolition of the vacant six storey office building on the site began in April 2007 to make way for the new tower. Brookfield started on site in December 2007 on a 29 month build programme.
Overall construction cost is £113.5M. Structural engineer is WSP Group with URS as environment assessment consultant and Norwin as turbine consultant and contractor.
