Lighting the Way
Hong Kong International Airport (HKIA) is one of the world's busiest airports. Operating round-the-clock every day, HKIA is a transportation hub that never sleeps. Simply lighting the facilities requires over 130,000 special lighting of different types – accounting for around 10% of the total energy consumption at the airport. To ensure the quantity and quality of lights for safe operations and visitor convenience while meeting energy savings targets, the Airport Authority (AA) spearheaded a project to upgrade conventional lighting with more environmentally-friendly Light-Emitting Diodes (LED).
In 2009 the AA began its LED replacement programme, the largest project of its kind in Hong Kong. At the time there were a number of challenges facing this ambitious initiative including an immature market for environmentally-friendly light solutions and limited supply. To overcome these barriers, the AA's Technical Services Department worked with the Government's Energy Liaison Group to develop a set of far-reaching specifications for LED lighting in Hong Kong. These specifications have since become the AA's procurement standard and set a benchmark for other large organisations' replacement programmes.
LEDs consume less energy than conventional lighting, helping to reduce environmental impact and energy costs. The project was completed in March 2015, 100,000 LED lights were installed, covering various facilities and areas, saving around 18.2 million kWhr of electricity annually and reducing CO2 emissions by 11,500 tonnes. The AA is also sharing its best practice and expertise in LED technology with tenants to ensure a bright, environmentally conscious future for HKIA.
Did you know?
The lifespan of LED lights are around 50,000 hours, versus less than 10,000 hours for compact fluorescent tubes. Therefore LEDs have longer replacement and maintenance cycles than conventional light bulbs.
