When it comes to sustainability, urban environments pose a range of unique challenges to developers. Due to constrained development sites, the close proximity of surrounding buildings and noise and air quality concerns a central city location does not lend itself to large-scale energy generation through the use of solar photovoltaics, wind power, biomass heating or gas fuelled Combined Heat and Power Plant (CHP). However Land Securities is committed to finding sustainable solutions wherever possible.
Conservatively, the Fuel Cell will reduce the carbon dioxide emissions of the building by at least 270 tonnes per annum
