Balancing digital growth with sustainability has become critical for organizations. While rapid digitalization has spurred the need to enhance digital infrastructures, this should not be done at the expense of the environment. Digital Realty will be launching its 3rd data centre in Singapore on April 6th, 2021. Named Digital Loyang II or SIN12, we are proud to say it builds upon Digital Realty’s track-record of sustainable development.
Our Commitment to Sustainability
We have a responsibility to expand sustainably as demand for data centres continues to rise. SIN12 is sustainably designed to utilize up to 50MW of power to provide critical digital infrastructure to customers as they scale their digital business.
Sustainability is a global mandate at Digital Realty. We are a leading purchaser of renewable energy globally and have more energy star certifications than any other data centre provider. In line with the “Energy Reset” pillar under the recently announced Singapore Green Plan 2030, Digital Realty is also ensuring we are using cleaner energy and increasing our energy efficiency to lower our carbon footprint. SIN12 is designed to be among the most sustainable data centres in the region with a power usage effectiveness (PUE) of 1.25 and the Green Mark Platinum certification by the Building and Construction Authority of Singapore. We believe energy efficient data centres will spur enterprises to be more sustainable as they accelerate their journey to the cloud.
SIN12’s Industry-Leading Sustainable Features
Sustainability is at the heart of the design and construction of SIN12. We incorporated indirect evaporative cooling systems, where outside air cools an internal environment without allowing internal and external airstreams to mix. This reduces the energy required for cooling and improves the water-use efficiency (WUE).
Additionally, our advanced Building Management System (BMS) monitors thousands of data points in the data centre to help identify areas with inefficiency energy usage. This system monitors the data centre load in real time and feeds back a data set that enables the smart control systems to use the least amount of energy needed to keep the IT equipment at the correct temperature. This data set is then presented in the form of a dashboard for real time monitoring and further evaluation, if needed.
For power generation, we are moving away from utilizing engines with pistons, to highly efficient Turbine Generators (TG). These generators not only produce lower noise and vibrations, but allow us to be more environmentally friendly with cleaner emissions while obtaining the same amount of energy. We are also using a combination of highly efficient UPS (uninterruptible power supply) and lithium-ion batteries. Compared with traditional batteries, they are able to accommodate significantly higher energy density within a more compact size, boast a much longer life expectancy and are more environmentally-friendly options. They can also be operated at higher ambient temperatures, making them an ideal solution for Singapore’s climate.
The need for data centres is here to stay as long as digitalization continues to take centre stage. The digital economy is growing at an exponential rate and data centres are the backbone of this burgeoning economy. Tech companies and data centre service providers have to lead the way in sustainable growth as part of our responsibility to tackle climate change. Digital Realty is committed to ensure we are expanding sustainably. Beyond SIN12, we are excited to double up our efforts to address climate change by working with our partners, vendors, customers, and employees to build toward a cleaner, carbon-neutral future.
