A planned £321m extension at Great Ormond Street Hospital in London is designed to use 20% less energy than a conventional building of its size.

Services by WSP Group include co-generation and cooling, adiabatic cooling techniques, heat/cooling reclaim and mixed-mode ventilation. A natural-gas-fired CHP plant is connected to the entire hospital campus. Boiler plant can in the future run on bio-gas to the generators or bio-oil to the boilers. Architect is Llewelyn Davies Yeang and construction starts in October for completion in 2011. For more healthcare projects, see 'Repeat performance'.
