Vaisala introduces Origo for data centre cooling efficiency
VANTAA, Finland, 2 February 2026: Vaisala highlighted the impact of minor temperature inaccuracies on cooling efficiency in global data centres. Making the announcement through a Press Release, Vaisala said roughly 80% of the world’s data centres still rely on air cooling and that correcting a 0.5 degrees C measurement error could avoid around USD 805 million in cooling waste annually across moderate 10 MW sites. Vaisala added that this could amount to approximately USD 8 billion in avoided waste over a decade.
Vaisala said it introduced Origo as a next-generation modular measurement platform designed to support environmental monitoring in data centres and other mission-critical buildings.
The company said a temperature sensor deviation of just 0.5 degrees C may appear insignificant but can result in more than USD 800,000 in wasted cooling energy over ten years in a 10 MW data centre. Vaisala added that in life science cleanrooms, even small inaccuracies in parameters such as temperature or relative humidity can compromise product integrity or research outcomes, with losses extending beyond energy costs.
Vaisala said there are an estimated 12,000 data centres worldwide, with the United States and Europe accounting for more than half. Vaisala added that while liquid and hybrid cooling solutions are expanding rapidly for high-density AI workloads, air cooling continues to form the universal foundation of data centre thermal management. The company further said hybrid architectures combining air cooling for space-level requirements and liquid cooling for dense loads are now standard in both new build and retrofit projects.
Vaisala said reliable and precise measurement is essential for optimising air-cooled environments. Anu Kätkä, Product Line Manager, HVAC and Critical Buildings, Vaisala, said: “Generic sensors with ±0.5 degrees C accuracy drive overcooling and energy waste, costing operators tens of thousands of dollars annually. Origo’s precise ±0.1 degrees C and ±1 percent RH accuracy and stable measurements reduce unnecessary cooling while ensuring the reliable environmental control that critical facilities depend on. It translates to performance that pays for itself in months and protects uptime for years to come.”
Vaisala noted that data centres currently consume about 1.5% of global energy and that demand is expected to more than double by 2030. The company said precision sensing is essential to managing energy use and emissions while safeguarding IT performance.
Vaisala said Origo is engineered for simplicity and long-term adaptability through a modular design that supports multiple measurement parameters using compatible probes, including carbon dioxide and dew point sensors. The company added that this flexibility allows the platform to adapt to evolving requirements in environments such as cleanrooms, life science facilities and semiconductor manufacturing.
Vaisala said Origo is backed by the company’s commitment to reliability and is designed to deliver accurate measurements throughout its service life. Vaisala said field-replaceable probes enable quick on-site updates with minimal interruption and that a range of services, including accredited calibrations and technical support, is available to complement on-site expertise.
