Chiller refresh plans for Hong Kong
Deputy Prime Minister Heng Swee Keat.
GOVERNMENT AGENCIES IN Singapore will be undertaking a chiller refresh as part of re- cently announced sustainability goals for the public sector.
As part of the Singapore Green Plan 2030 the government will switch to chillers that use re- frigerants with low global warming potential.
Deputy Prime Minister Heng Swee Keat said the initiative, known as GreenGov.SG is part of the Singapore Green Plan 2030, which was an- nounced to fight climate change.
"This gives renewed focus to the public sector's contribution towards national sustainability goals, and reminds all public officers that sustain- ability must be at the core of our work,” he said.
The Green Plan, announced last month, is a
blueprint that outlines all of Singapore's sustain- ability efforts to reach the nation's long-term goal of net zero emissions as soon as possible.
The chiller refresh will begin at the Ministry of National Development (MND), Home Team Academy and Temasek Polytechnic.
Temasek Polytechnic's School of Engineering will be replacing five old and inefficient chillers at a cost of about $4.25 million.
Last year, the National Environment Agency said it would be progressively phasing out cool- ing equipment that use refrigerants with high global warming potential for household and commercial use, and would ban the supply of certain air-conditioners and chillers from the fourth quarter of next year.
