Singapore's Green Data Center Roadmap: PUE 1.3 Ahead, and 1.25 for New Capacity
Singapore has not passed a hard PUE law for existing data centers, but it has set the direction and made efficiency a priority for data centers that wish to expand. The National Green Data Center Roadmap, launched on May 30th 2024, aims to bring every data center in Singapore to a PUE of 1.3. An initial release of 300MW of new capacity was awarded only to projects that hit 1.25. If you operate in Singapore, or want to, PUE is now the number that determines your chances.
What the roadmap actually defines
Roadmap Target (all data centers). In 2024 the Infocomm Media Development Authority (IMDA) launched the Green Data Centre Roadmap. It aims to uplift all data centers in Singapore to a PUE of 1.3 or better at 100 percent IT load, over roughly the next ten years. This is an aspiration, not a statute with a penalty.
Capacity Conditions (new builds). Singapore allocates scarce new data center capacity through periodic Calls for Application. The most recent one, DC-CFA2, required winning projects to achieve a PUE of 1.25 at 100 percent IT load, use IT equipment meeting the SS 715:2025 efficiency standard, reach BCA-IMDA Green Mark Platinum, and power a large share of the new load with green energy.
The message is clear: your PUE defines which facilities can grow and those that can’t.
Where you cannot fake the number
Compliance comes down to measuring PUE honestly and continuously, not estimating it once a year.
In Quicklime, AKCP’s DCIM platform, PUE is a live value fed by power meters on the facility and IT sides, updated continuously and alertable like any other sensor. Around it sit the measurements that explain the number and a Green Mark submission expects: per-rack inlet and outlet temperatures, hot and cold aisle differentials, and per-outlet power metering from the Thermal Map sensor range. AKCP has built monitoring hardware since 1981 and monitors more than 200,000 facilities; they have the knowledge and expertise to make sure you have the data you need to accurately monitor and report not only PUE, but the numbers that surround it.
Closing the gap before it is a bid requirement
Once you know your PUE, if it’s missing the mark, the challenge then is how to improve it. sensorCFD runs AI-assisted computational fluid dynamics simulations seeded by a facility’s live sensor data, so a proposed change, new containment, a raised CRAC set point, or a rack rearrangement, can be tested against the room as it actually behaves before anyone moves hardware. For an operator eyeing the next capacity call, that turns a target into a plan.
Frequently asked questions
Is PUE 1.3 the law in Singapore?
No. PUE 1.3 is the aim of the IMDA Green Data Centre Roadmap, a direction set for the industry over about a decade, not a statute with a deadline or a penalty. It is worth preparing for, not a compliance date.
Then where does 1.25 come from?
From the capacity side. The most recent Call for Application for new data center capacity (DC-CFA2) required selected projects to reach PUE 1.25 at 100 percent IT load, along with SS 715:2025 and Green Mark Platinum. It binds those awarded new capacity, not all existing sites.
Does this apply to my existing facility?
The roadmap’s 1.3 aim is directed at all data centers, existing ones included, but as a target to work toward with time to plan, not a rule you are currently breaking. The 1.25 condition applies to new-capacity bids. Either way, the operators in the best position are the ones already measuring.
Can AKCP certify my facility for the roadmap or a capacity bid?
No. AKCP is not an auditor or a certification body. What AKCP provides is the continuous PUE, power, and thermal measurement these targets and submissions rely on, plus the airflow analysis to help improve the number. The determinations remain yours and the assessors’.
See where your facility stands today
The fastest way to know how far your Singapore site is from 1.3, or whether it could make a 1.25 case for new capacity, is to look at the live numbers. AKCP runs a free PUE Health Check: a 15-minute session on your facility’s PUE drivers, where the energy goes, and what would move the number.
