klia2: “Embracing Energy Efficiency for Sustainable Aviation”
Malaysia Airports Holdings Berhad
INTRODUCTIONklia2 is the second terminal of KL International Airport (IATA Airport Code: KUL), which is under the management of Malaysia Airports. It is capable of handling up to 45 million passengers per annum (mppa) and occupies a site area of about 232,000 sqm. klia2 was designed based on energy efficient design criteria and was certified Gold in Leadership in Energy & Environmental Design (LEED) Green Building Certificate. Malaysia Airports has ensured that klia2 leads in Green Airport Sustainability and is aligned with the Sustainable Development Goals. On top of which, Malaysia Airports also supports Malaysia’s aim of 45% carbon reduction by 2030. Malaysia Airports also has a long-term masterplan formulated under the KUL sustainability charter. As such, the development of klia2 ensured the incorporation of green design features during its construction. Among the objectives of the KUL sustainability charter is to achieve carbon neutral status. For 2018, the target was set at 2,344tCo2 which it exceeded by achieving 3,132tCo2.
FRAMEWORK AND STRATEGYExceeding the carbon reduction target was achieved through the various ways such as utilising chilled water for the airconditioning cooling system, efficient lighting planning, smart travellator features that detect people movement, energy efficient automatic baggage handling system, utilisation of CO2 sensors to regulate airflow, using renewable energy via solar farm to help generate electricity for terminal building’s operations, and the use of smart water efficient fittings to reduce water usage. Apart from the green infrastructure design, klia2 also embraces green architecture by emphasising the design, material and impact on overall green sustainability. Among the vital outlines in this sustainability design features include building orientation to capitalize on daylight, shape of building to maximise the capture of rainwater and heat transfer, spatial organisation to maximise the space and energy usage, envelope design in materials used to reduce and absorb less heat. Apart from that, other green initiatives undertaken were on waste management, pollution management, and utilising green and sustainable products.
ACHIEVEMENT AND IMPACTAll of the above measures helped to achieve various positive environmental impacts in 2018. For waste management, the solid waste disposed was 2,018.52 tonnes. For renewable energy, the solar farm generated 13,452,899 kWh electricity representing 32% of the terminal’s consumption. Having achieved the carbon reduction target of 132tCo2 for 2018, the target set for 2019 is a 5% increment from the previous year at 3.288.6tCo2.
FUTURE DIRECTIONMalaysia Airports sustainability practices is an on-going effort where new green initiatives are constantly being implemented. These new initiatives are spearheaded by the Company’s Environment Management Committee (EMC) under the Malaysia Airports’ Green Airport Strategy Roadmap. The EMC is led by Ir Khairiah Salleh who is also the Chair of the Airports Council International (ACI) Asia Pacific Regional Environment Committee. This committee outlines strategic priorities in energy management, water conservation, waste to land filled reduction, waste water, fuel, noise, wildlife and carbon reduction initiatives. Current focus include developing the Follow the Green system for Aeronautical Ground Lighting (AGL) system by utilizing LED lighting, deployment of more Electric Vehicles (EV) leasing cars to replace petrol/fuel cars, enhancement of Air Conditioning and Mechanical Ventilation (ACMV) system by integrating Artificial Intelligence (AI) Technology, and also the utilisation of retention pond/ sewerage treatment plant as sustainable water recycling projects.
Malaysia Airports is one of the largest airport operator groups in the world—in terms of number of passengers handled—managing 39 airports across Malaysia (with five international airports, 16 domestic and 18 STOLports) as well as one international airport in Turkey.
