In 2023, the primary focus was placed on furthering energy efficiency efforts such as:

• Replaced over 4,000 fluorescent light tubes with energy efficient LED.
• Adjusted the Chilled Water System (CHWS) from 7°C to 9°C.
• Introduced an AI-augmented optimisation system to the hospital’s chiller plant.
  

As a result of all the efforts, GHK was able to achieve a 15.1% reduction in energy intensity as compared to the 2022 baseline.
