Energy efficiency at the new terminal 2

Sustainability case study

As Heathrow's owner, we are investing in energy efficient technology and renewable energy.

This will cut carbon dioxide (CO2) emissions from Heathrow’s redeveloped Terminal 2 by over 40% compared to the minimum specified for a new building.

With over £60 million spent on energy to run Heathrow every year, this will also help to reduce operating costs.

Technical studies identified the most appropriate energy efficiency design elements, for example use of high levels of insulation and passive lighting. Taken together, these enable the building to be 20% more energy efficient than the minimum specified by planning standards.

The inclusion of renewable energy sources will reduce the building's CO2 demands by a further 20%.

The renewable energy for the building will come from photovoltaic solar panels on the roof, and more significantly through a combined heat and power (CHP) plant that will be fuelled with wood chips, sourced locally to Heathrow. This biomass CHP will be the largest of its kind in London.

The biomass CHP plant also forms part of a wider Heathrow energy strategy that will see the airport's CO2 emissions from the use of buildings and equipment, fall by at least 34% by 2020, compared to 1990.
