The new Great Ormond Street Hospital (GOSH) redevelopment will provide all its own energy, aims to be carbon-free, and supply some 20% green energy to other parts of the site as well as aiming to have 20% more capacity to treat sick children by the end of the redevelopment in 2016.

The new 30,000 square metre Mittal Children's Medical Centre, designed by UK-based architectural practice Llewelyn Davies Yeang (LDY), consists of two linked buildings to be constructed over two phases. It comprises the Morgan Stanley Clinical Building and the radical reconstruction and refurbishment of the old cardiac wing. Together, the Mittal Children's Medical Centre will house new wards, operating theatres, imaging facilities, offices and a staff and family restaurant.

The Trust has set the centre a target of 120% carbon reduction and 60+% renewable energy contribution by 2016 (in line with Greater London Authority (GLA) targets). This is achieved in part by Combined Cooling, Heating and Power (CCHP) units and the potential to use biofuels extracted from sustainable resources.


The first phase of the centre, the Morgan Stanley Clinical Building, will feature many energy-saving technologies, including:

• CCHP technology with two tri-generation units providing heating, cooling and electricity, in addition to sensor taps, efficient toilets, showers and appliances. The design achieves a reduction in carbon emissions over and above current building regulation standards
• Natural daylight, presence detectors and LED lighting will all help to reduce energy consumption further
• A glazed natural ventilation flue will extend the full height of the building, naturally ventilating the restaurant on the ground floor
• The bedrooms also use mixed mode natural ventilation
• The glazed facade maximises the amount of daylight to the building's interior whilst minimising the solar gain internally
• As well as natural ventilation and lighting, the green design utilises natural paints and linoleum, and low Volatile Organic Compounds (VOC) materials have been selected in the vast majority of the interior finishes
• All timber will be Forest Stewardship Council (FSC) certified coming from a sustainable managed source
• Sedum roofs

Bill McGill, GOSH Director Of Redevelopment, said: "We believe this is as green as it is possible to get for a central London building. We have faced up to the challenges of the hospital's location, got through stringent planning procedures and will be ready to start building this spring.

"The redevelopment design is being used as an example to other developers and our energy assessment is being used by the Greater London Authority as a guide to best practice in London, something we're very proud to achieve."
