Green heating system unveiled at London shopping centre
Land Securities has unveiled the green heating and cooling system installed at its One New Change shopping centre in central London.
The technology both heats and cools the building by transferring thermal energy from the ground and two water wells located 150 metres below the surface through 60 kilometres of piping laid underneath the complex.
Controls fitted alongside the system allow users to independently heat and cool different sections of the property as needed.
According to the commercial property company, which is the UK's largest, the installation could reduce carbon emissions by ten percent and save £300,000 on energy bills.
Patrick Sherriff, from Geothermal International, the firm that designed the system, said: "Today is the culmination of a three-year project, working closely with Land Securities and building partners to design and install one of the most sophisticated ground source heating systems in the world."
Climate change minister Greg Barker officially switched the system on and said it was "an example of British innovation at its best".
One New Change has been granted an "excellent" rating under Breeam (the Building Research Establishment Environmental Assessment Method).
