Airports are the very valuable asset of a country. Remarkably, Airports plays a very significant role in the country’s revenue. Knowing the importance of the green and energy efficient buildings, blue prints of the budding airports encompasses more eco-friendly and sustainable features. Moreover, the existing airports started to emerge as very efficient airports by revamping their infrastructure with energy efficient features. This saves the expenditure to a notable extent by saving the energy. Here is the list of three famous energy efficient airports in the world.

Heathrow Airport

heathrow1Heathrow Airport is the world’s very busiest international airport in London, UK. This airport belongs to BAA, a leading airport company holding many airports in UK. As a part of the revamping plan of BAA, a very outstanding solar and renewable energy powered airport terminal with investment of £1 billion was designed. This energy efficient terminal is expected to emit 40 percent less carbon when comparing to other existing conventional buildings. This terminal is designed by foster along with its partners.

The design of the terminal consists of many large north facing windows, which will flood the natural daylight inside the terminal. Thus saving the electricity cost to a prominent extent. The roof with very efficient solar system will provide renewable energy to the building and it is coupled with energy center to provide heating and cooling and it is fueled by renewable resources itself. This airport also unveiled a lower energy, battery powered driverless airport pods, which generates no local emissions and moreover it is 70 percent more energy efficient than other cars and 50 percent energy efficient than the traditional buses.

San Francisco International Airport

sanSan Francisco International Airport is located at San Francisco, California. The renovation plan of this San Francisco International Airport’s Terminal 2 (T2) encompasses many energy efficient and sustainable features. Some of the sustainable elements included in this renovation will minimize the green house gas emission by 1,667 tons per year. Electrical lightings and machinery will leads to the electrical consumption by 2.9 giga watt hours per year. The project also includes sensors at hangars and daylight harvestings that will automatically turn the light off when the space is not in use or when there is adequate sunlight inside.

This airport is working forward to achieve the 75 percent recycling by 2010 and 90 percent recycling by 2020 and for this attainment the T2 food vendors will be requested to use biodegradable tableware and the source separate all food waste and direct it to the off-Airport composting facility. The revamping planning also includes a dual plumbing system. Stand-alone plumbing system in the toilets and urinals will be supplied with the recycled water from the Airport’s Mel leong treatment plan.

To reduce the carbon foot prints, T2 includes preconditioned (PC) air and 400 Hz to the aircrafts at T2 gates that helps the aircraft auxiliary power units (APU) to conserve 1,400,000 gallons of jet fuel per year. It also reduces the carbon dioxide emission by 15,000 tons per year. San Francisco International Airport planned to install hydrogen fueling station fuel cell vehicles as a part of reducing carbon footprints.

Denver International Airport

denver-Denver International Airport is sited at Colorado, USA, covers many innovative sustainable features. The roof of the Jeppeson Landside terminal of the Denver International airport is covered by the stressed-skin fabric that provides energy efficiency as well as natural day lightings. This terminal includes high performance glazing on all its fenestrations such as windows, doors, curtain walls or skylights. Jeppeson terminal also contains energy efficient lighting system; energy efficient mechanical system; and an advanced energy management and control system.

Denver International Airport is planning to build a solar electric-generating system at a cost of $ 7 million to generate power to its fuel storage and distribution system. Energy efficient escalators with the controllers soft start electric motors are implemented in this airport. Denver carried out a new contractor acoustic system replaces the old ceiling panels with ceiling grids, which will save $ 2 million. This aerodrome also planned to unveils a solar photovoltaic system. Denver Airport celebrated the Earth Day on 22 April, 2009 by distributing reusable grocery shopping to all the passengers in the Jeppeson Landside terminal.
