With data consumption climbing in both business and private contexts, operators face mounting challenges \u2013 driven above all by the growing energy demand of AI workloads. Power consumption is outpacing infrastructure growth and is pushing energy availability to its limits. At the same time, operators must comply with stricter rules on energy efficiency and CO2 reduction. Cooling plays a pivotal role here because it accounts for up to 30 percent of a data center&#8217;s total energy consumption. Globally, cooling energy use is expected to rise from 136 to 257 TWh by 2028, with costs climbing from around 17 billion euros to around 31 billion euros.<\/p>\n<h2>Intelligent cooling system optimization<\/h2>\n<p>NEXAIRA.Systems from ebm-papst offers a comprehensive answer to these challenges. This AI-driven Cooling Supply Optimizer helps data center operators cut energy consumption, reduce operating costs and hit sustainability targets \u2013 all while maintaining system reliability. The solution optimizes the entire cooling loop through intelligent control and coordination of every cooling component to deliver peak performance. The result: overall cooling system energy consumption drops by up to 50 percent \u2013 which is equivalent to the output of up to 128 terawatt-hours worldwide by 2028, or the generating capacity of 22 nuclear power plants.<\/p>\n<h2>A digital twin for peak performance<\/h2>\n<p>At the heart of NEXAIRA.Systems sits the Cooling Supply Optimizer \u2013 an AI-based energy manager that delivers the required cooling performance at the lowest cost, without compromise on safety or reliability. It creates a digital twin of the HVAC system in the data center&#8217;s grey space (including pumps, chillers, cooling towers and dry coolers) to simulate, predict and calculate the most efficient setpoints in real time. It factors in variables such as weather forecasts and load projections and enables fully automatic control via the building management system (BMS).<\/p>\n<p>This real-time control \u2013 reacting to demand and climate \u2013 reduces energy and water consumption in the grey space while ensuring safe, autonomous operation in the white space. The system also detects anomalies, enabling proactive maintenance, faster fault resolution and stronger ESG reporting with actionable data.<\/p>\n<p><a href=\"https:\/\/www.ebmpapst.com\/de\/de\/products\/nexaira\/nexaira-systems.html?utm_source=cloudmagazin_beitrag_13_10_2025&#038;utm_medium=advertorial_en&#038;utm_content=&#038;utm_campaign=NEXAIRASystems_2025\" target=\"_blank\" rel=\"sponsored noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-26607 size-large\" src=\"https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-700x700.png\" alt=\"Cooling energy costs cut by up to 50% with NEXAIRA.Systems from ebm-papst\" width=\"700\" height=\"700\" srcset=\"https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-700x700.png 700w, https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-250x250.png 250w, https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-150x150.png 150w, https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-768x768.png 768w, https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-120x120.png 120w, https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-24x24.png 24w, https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-48x48.png 48w, https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-96x96.png 96w, https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image-300x300.png 300w, https:\/\/www.cloudmagazin.com\/wp-content\/uploads\/2025\/10\/Cloud-Magazine-additional-image.png 1080w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/a><\/p>\n<p style=\"text-align:center;font-size:0.85em;color:#666;margin-top:-8px;margin-bottom:24px;\">NEXAIRA.Systems from ebm-papst: AI-powered cooling optimization cuts energy consumption by up to 50 percent \u2013 without replacing hardware.
