Bold, sustainable high-rise residence features world's first integral wind turbines 

Strata SE1 is a 148-metre-high, 43-storey residential development that creates a dynamic new landmark on the London skyline. The first building in the world with integral wind turbines, it sets a new benchmark for environmental strategy. This development, with 408 apartments enjoying floor-to-ceiling views of London, is a major catalyst for the on-going regeneration of the Elephant & Castle area in central London and was tasked with setting the benchmark for high-rise sustainable urban living in the area. The scheme provides a mix of market (310) and intermediate housing (98) in the form of shared equity (affordable) dwellings to satisfy direct local housing needs.

The building's form evolved in response to a number of key factors: Rights to Light, Daylight and Sunlight requirements for the adjacent Draper House defined a specific envelope for a tall building on the Site; creating an efficient floor plate and core suitable for residential space planning; a strong desire to design and configure the building from the inside out as well as from the outside in; the London Strategic view framework; and the desire to create a landmark building at the heart of the area's urban regeneration.

Strata SE1's striking aluminium-and-glass façade creates a building of distinctive character, with a clearly articulated base, middle and top zone. At the base of the building, outer layers have been peeled back to reveal glazing and create transparency for the retail and entrance to the building. At the top of the building, a similar approach has been taken to reveal a crystalline apex; a top and side-lit sky lobby provides access to the upper-level apartments.

The client's brief called for a concept embracing energy efficiency, targeting an EcoHomes assessment rating of 'excellent'. Located in one of the Mayor of London's Energy Action Areas, Strata SE1 embraces sustainable design and the latest renewable energy technologies. The three wind turbines are expected to produce 50 Mega Watt hours of electricity per year for the landlord's power supply. This figure is equal to approximately 8% of the building's estimated total energy consumption, which is enough to meet the total annual demand from 30 two-bedroom apartments, based on 2006 building regulations.

Other sustainable measures in the scheme include a bespoke, high-performance façade with an air permeability leakage rate that is 50% better than current building regulations, low energy lighting to all landlord areas. Apartment lighting is typically 40% low energy and 60% Tungsten lamping. 96% of all waste material generated during the construction stage was recycled. Strata will be connected to the planned Elephant & Castle MUSCo (Multi-Utility Services Company), a community combined heating and power scheme, which will provide heat and electricity from Biomass CHP energy centres. Independent analysis has compared CO2 emissions from Strata SE1 against the Building Regulations 2006 Part L2 targets. The result demonstrates that Strata SE1 will achieve a predicted 73.5% reduction in CO2 emissions when compared against the Building Regulations benchmark.
