dnata has successfully installed a new, innovative cooling technology in its facilities at Singapore Changi Airport (SIN), which is expected to save at least 650 metric tonnes of carbon and 1.5 million kilowatt hours (kwH) of electricity per year.
The introduction of Cooling as a Service (CaaS) provides chilled water and air conditioning through a reliable, efficient and sustainable solution. dnata Singapore implemented the CAAS, supplied by provider Kaer, in January 2022 to provide cool water and air to its cargo, catering and support facilities.
Under the CaaS model, Kaer retrofitted the cooling systems serving the two facilities with high efficiency, low-global warming potential (GWP) technology and have deployed their suite of data mining, machine learning and carbon monitoring software.
dnata said this has resulted in a 54 percent reduction in energy consumption at its cargo base, and a 35 percent reduction at its catering and support offices. The technology also allows for real-time monitoring and reporting of service levels, as well as energy use and carbon emissions for ESG reporting.
Dnata has already reduced its electricity-related carbon emissions in Singapore by 20 percent through the use of a rooftop power plant which comprises of 6,500 individual solar panels, generating over 4,300 megawatt hours of green power each year. The energy savings achieved by the new cooling systems is the equivalent to installing an additional 2,400 rooftop solar panels.
Charles Galloway, dnata’s Regional CEO, airport operations Asia Pacific, is proud of the company’s early adoption of low-GWP refrigerants in Singapore, as dnata looks to make its operations even more efficient and sustainable.
“We have plans to expand our CaaS initiatives to additional areas of our operations, and look forward to working with our partners to further reduce our environmental footprint.”
dnata recently announced that it was on track to reduce its carbon footprint and waste to landfill by half by 2030 as part of its 8-year green operations strategy. The company has committed US$100 million to implement green technology and initiatives across its businesses globally to achieve its strategic objectives, which include significant investment in infrastructure, green ground support solutions and process improvement.
