Our target is to cut carbon emissions by at least 50% relative to 2005 levels through energy-efficient building design, the application of the latest technologies and connection to a site-wide Combined Heat and Power (CHP) distribution network.

All buildings will connect to the heat network which will be fed by a CHP energy centre. The power generated at the CHP plant will also be used to supplement supplies from the national grid.

The cooling demands of the office buildings, which represent the largest energy requirement on the site, will be met by a combination of absorption chillers fed from the district heat network (tri-generation) with any extra demand met from efficient mechanical chillers. Cooling systems will use the best chilled beam technology in order to minimise energy use.

We are also using other renewable technologies, including roof-mounted wind turbines, photovoltaics, ground source heat pumps and solar thermal systems for generating hot water.

King's Cross allows us to approach things differently.
