What’s the cost of a half-degree? Vaisala’s new Origo slashes cooling waste in data centres?

Roughly 80% of the world’s data centres still rely on air cooling. Fixing a ‘half-degree’ error there can avoid around $805 million in cooling waste every year, about $8 billion over a decade, based on moderate 10 MW sites.

Vaisala, a global leader in measurement instruments and intelligence for climate action, introduces Origo, a next-generation modular measurement platform designed to transform environmental monitoring in data centres and other mission critical-buildings.

Why half a degree matters

A temperature sensor off by just 0.5 °C (32.9 °F) might sound trivial, but for example in a 10 MW data centre, that small error can cost more than $800,000 in wasted cooling energy over ten years. In life science cleanrooms, for example, the stakes are even higher: any critical environmental parameter such as temperature or relative humidity can compromise product integrity or research outcomes, with losses that go far beyond energy costs.

Air cooling remains essential in a rapidly evolving data centre market

There are an estimated 12,000 data centres worldwide, with the U.S. and Europe accounting for more than a half. While liquid and hybrid cooling are growing fast for high density AI workloads, air cooling remains the universal foundation of data centre thermal management. It provides the room-level baseline cooling every facility needs, while liquid cooling adds targeted, high efficiency heat removal for the hottest racks. As a result, hybrid architectures —air for space, liquid for the densest loads— are now standard in both new builds and retrofit projects.

Impact at scale

Reliable, precise measurement is critical for optimising air-cooled environments.

“Generic sensors with ±0.5 °C accuracy drive overcooling and energy waste, costing operators tens of thousands of dollars annually. Origo’s precise ±0.1°C and ±1 %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,” says Anu Kätkä, Vaisala’s Product Line Manager for HVAC and Critical Buildings.

Applied at global scale, eliminating the “half-degree” error across predominantly air-cooled installed base — roughly 80% of the world’s ~12,000 data centres — would avoid around $805 million in wasted cooling energy every year, totaling approximately $8 billion over a decade.

With data centres consuming about 1.5% of global energy, and demand set to more than double by 2030, precision sensing is essential to keep energy use and emissions in check while safeguarding IT performance.

Designed for tomorrow’s critical environments

Origo is engineered for simplicity and long-term adaptability. Its modular design enables monitoring of multiple parameters through Vaisala’s compatible probes, such as carbon dioxide (CO₂) and dew point sensors, on the same platform. This flexibility makes Origo a future-proof solution that adapts to evolving measurement requirements also in other critical environments such as cleanrooms, life science applications, and semiconductor manufacturing.

Backed by Vaisala’s commitment to reliability, Origo ensures accurate measurements and dependable performance throughout its service life, helping operators protect processes, reduce risk, and optimise resources.

Origo’s field‑replaceable probes allow quick on‑site updates with minimal interruption. Vaisala’s wide range of services, from accredited calibrations to technical support, is available to complement on‑site expertise.
