T2; our most sustainable terminal yet
Sustainability case study
Millions of people rely on Heathrow to connect them to the world. Our job is to help them travel smoothly and swiftly through the airport.
Since 2003 Heathrow has invested £11 billion on transforming the airport to make the journey of every passenger better, and the opening of the new Terminal 2 is the next step in this transformation.
Because Heathrow is committed to maximising social and economic benefits the airport generates, while minimising its impact on the environment; sustainability as a guiding principle in the design, construction and functionality of T2. This means it will be Heathrow’s most sustainable terminal yet.
Airports operate more efficiently with a smaller number of larger terminals arranged in a more regular layout. T2’s size and proximity to the runways are helping Heathrow move towards this structure; reducing aircraft taxi times and CO2 emissions.
Larger, more efficient aircraft such as the A380 can operate from Terminal 2. A380s have the lowest fuel burn per seat of any commercial large aircraft and emit half the noise of their nearest competitor.
T2’s shape and design features aren’t just a pretty façade. The skylights and 10-metre-high, floor-to ceiling windows maximise the natural light, while the roof’s north-facing skylights provide glare-free daylight all the way from check-in to aircraft boarding.
Terminal 2 has been recognised for best practice in sustainable construction by becoming the world’s first BREEAM certified airport terminal. BREEAM is the world’s foremost environmental assessment method and rating system for buildings.
The building of Terminal 2 has also created many new construction jobs across the country, around 35,000 jobs in total. To equip people with the right skills, we provide a wide range of training and development opportunities through the Heathrow Academy.
We recycled over 99% of demolition waste from the old Terminal 2 - including concrete, metal, plastic and timber.
Once in full swing, the building’s CO2 emissions will be more than 40% lower than Building Regulations require. This will in part be thanks to the terminal’s own renewable-energy centre providing combined heat and power fuelled by woodchip; reducing emissions to air and cutting CO2.
Sophisticated lighting control systems will also keep energy use down by switching off the LED lights when parts of the building are not in use or when daylight is bright enough.
Water-efficient fittings in the terminal reduce water consumption. To cut the use of potable water even further, there are boreholes which will supply most of the water for the cooling plant and toilets.
We aim to recycle or compost 70% of airport waste by 2020. Within Terminal 2, waste management and segregation at source will help us reduce and better manage operational waste.
