Making Every Journey Greener


Designed from the outset with a focus on individual passenger needs and sustainability, and a vision of ‘making every journey better’ Heathrow’s new Terminal 2 is setting a new standard for greener more efficient airports. When completed, the entire project will have a capacity of 30 million passengers a year and will cost £1–1.5bn. 


The new Terminal 2 will produce 40% less carbon dioxide emmissions, than the buildings it replaces. 20% of this target will be achieved through energy efficiency design technology elements, such as high levels of insulation, LED lighting and passive lighting. Also large north-facing windows in the roof will flood the building with natural light, reducing the need for artificial lighting, without generating excess heat. Photovoltaic panels on the roof will further reduce dependency on energy supplies. The second 20% carbon reduction will be due to the new T2 Energy Centre, via biomass CHP fuelled by woodchips from local renewable resources, which will provide heating and cooling to both T2 and T5. 



“The new Terminal 2 building will reward flyers with a modern, technologically progressive and sustainable environment.”



BAA have put sustainability and efficiency at the core of the Terminal 2 project. Green-fuel heating boilers, solar energy and smart lighting control all help reduce energy use, and have ambitious targets on water use and waste management, here Zonecheck ticks both boxes, not only is it 100% water saving, from a logistics point of view Zonecheck is increadibly efficient when compared to conventional methods. When Terminal 2 is finished, with Zonecheck installed, it’s fire systems can all be tested remotely from the building management system (conventionally a trained engineer would have to travel around the building and test every flow-switch individually). These out dated methods, while are imperative to the safety of the passengers at the airport cause a lot of disruption especially in high security buildings, also airports are open 24/7 so there is seldom a good time to carry out these tests. 



A Greener Way to Work

In order to reduce the impact of the new facilities at Heathrow every significant affect on the environment has been taken into consideration including the use of natural resources. The fact is airports use a significant amount of water and BAA Heathrows owner are takling water comsumption by monitoring water use at the airport, checking for leaks, setting water efficiency targets, installing water efficient technologies and encouraging the retro-fitting of water saving devices throughout their airports. To reduce the use of potable water action was taken to review the technical design standards for water intensive assets where Heathrow’s fire sprinkler system fell into this category. Maintaining the sprinkler system at Terminal 2 would normally require large amounts of water to be drained off in order to carry out testing (320 litres per flow-switch, there are a total of 125 flow-switches to be installed at the two Terminals) these tests ensure the system remains ‘fit for purpose’. Our Zonecheck flow-switch testing device is a modern, sustainable way to carry out these tests without the need discharge any water from the system, saving at total of 1280 litres of water per flow-switch annually. With a total of 125 flow-switches to be installed throughout Terminal 2A and T2B, this is a total water saving of 160,000 litres of clean drinking water!


Terminal 2’s satellite building Terminal 2B won a prestigious gold award for sustainability from The Green Apple Awards. Realising the Terminals execution in sustainable contruction, design and innovation, and rewards projects which achieve a low carbon footprint. The award was given for initiatives such as using reusable energy in it’s power substations, the use of construction soil to create new green space and using energy efficient technology throughout the Terminal. Its safe to say that our Zonecheck played a small part in helping Terminal 2B in winning this prestigious award.


So not only is Zonecheck sustainable, saving 100% of the water which is normally discharged to waste it provides the building operator with numorous benefits. Zonecheck saves time and cuts costs when carrying out routine tests on fire sprinkler systems. No additional man power is required plus no fire pumps or alarms are activated during testing. Zonecheck is fully approved to all major international approval bodies including LPCB. 


The new structure at Heathrow has been designed around the needs of the individual passenger although the new facilities will also make the maintenance of the building much easier by installing modern time saving technologies such as Zonecheck.
