The healthcare sector is one of the most energy-intensive built environment worldwide accounting for a range of 5 to 8 percent of global energy consumption. In quest for a green sustainable and eco-friendly healthcare system among all public hospitals, it is a challenge of reducing energy consumption and greenhouse gas emission but without compromising quality of clinical services and pleasant environment, seemingly a double edged sword scenario. Despite HA has long history in embarking into promoting energy savings which started from 1998 with simple staff energy saving awareness measure toward a recently wide array of energy saving initiative across the public hospitals, it remains a definite commitment with clear energy saving goal. In 2016, HA has resolutely moved into target based approach and committed to the Government's 4T (Target, Timeline, Transparency and Together) Charter of pursing 5% energy saving by 2023 using 2015 as baseline. Via various energy saving initiatives like replacing for more efficient building services equipment, adopting of advanced LED control system and carrying out Retro-commissioning etc. and the saving has exceeded the target. Looking ahead, HA has also venturing into new government's announced Carbon Neutrality policy, that is aiming for a cumulative 15-20% energy savings by 2035. Apart from implementing previous successful energy-saving measures, HA is exploring more innovative initiatives such as installing advanced Tri-generation Plant that generates electricity, cooling, and heating within hospital by using renewable landfill gas. HA is also actively considering the use of hydrogen which is now being considered at the forefront of a green fuel driving power generation for our future.
