KLIA2 airport

KLIA2 airport

The airport was designed to be energy efficient and to achieve both LEED Gold and GBI green building certification. The airport achieved 26% energy savings compared to base building under LEED. The passive design of the airport includes a well insulated white coloured roof with a low U-value of 0.335 W/m2 K; special attention was paid to reducing thermal heat bridging by 42% through carfull design and insulation of the roof steel members. The airport is designed for 33% daylight autonomy with double-glazing for all facade glazing and with 3% of the roof being skylights. The cooling load was reduced by designing for thermal stratification for the air-conditioned zones, so only the bottom 3.5 meters of the space is air-conditioned. Energy efficient air-foil fans and variable speed drive (VSD) energy efficient motors were used for all air-handling units (AHU). Fresh air was regulated using CO2 sensors placed in the breathing zone with a setpoint of 850 ppm. The airport is connected to a centralised district cooling system with a system COP of 4.22. The baggage handling system was made efficient by using low-friction luggage belts, energy efficient motors and controls, as to minimise - when possible - the operational hours and speed of the individual luggage belts. This airport has the biggest rainwater harvesting system in the country.
