Thermal optimization

Thermal optimization in data centers from Siemens

Cooling accounts for the largest part of electrical energy consumption in data centers after IT. Our integrated management solutions and services can monitor and manage your data center cooling systems and related air flows. This helps to safeguard continuous and efficient operations. We help you approach cooling from all angles — by leveraging the expertise of our technicians or experienced industry partners, we increase thermal reliability, optimize equipment maintenance and reduce operational costs.

Whitepaper: How artificial intelligence is cooling data center operations

This paper explores AI and its impact on data centers, using White Space Cooling Optimization as an example of how AI can be implemented today. Furthermore it reviews how a global financial firm is using White Space Cooling Optimization as part of its thermal optimization plan.

Siemens Xcelerator

Accelerating the digital transformation

Siemens Xcelerator is an open digital business platform and marketplace with the ambition to create a powerful ecosystem of partners who can jointly accelerate digital transformation tailored to your specific business goals. Making digital transformation easier, faster and at scale.

White Space Cooling Optimization

White Space Cooling Optimization delivers dynamic cooling management for the data center data hall. The solution, White Space Cooling Optimization, uses an on-premise software leveraging data from a dense sensor mesh and an advanced machine learning model to analyze and automatically optimize the cooling distribution on rack-level. Main customer benefits are increased thermal reliability (the solution dynamically manages a maximum rack temperature much more closely and reliably) and energy savings. 


Thermal reliability:


  • Automatic hotspot reduction + visual guidelines for ongoing improvement
  • Increase reliability through intelligent maintenance

Energy savings:

  • 38% ongoing cooling energy savings averaged across 500+ installations
  • 5 to 10% PUE improvement
  • < 3 years simple payback

More IT:

  • New capacity for IT expansions 

Siemens will coordinate on-site deployment and software setup, savings will be documented against baseline. Customers have access to the system user interface, delivering equipment and cooling performance insights via dashboards, influence maps, trends etc. as well as notification tab reports on alarms by criticality.

Chiller Plant Optimization 

Demand Flow™

Demand Flow is an HVAC optimization solution that reduces energy costs and ensures ongoing operational efficiency, with healthy financial returns and long-term value. Whether our Demand Flow for chilled water (CHW) or variable air volume (VAV) system optimization product, this patented solution delivers immediate results through our automated technology and built-in analytics that alleviate constraints on our customers’ internal resources & extend equipment life.


The Demand Flow algorithms also ensure that energy is not shifted from one plant sub-system to another, as in some other energy conservation routines. Demand Flow measures and verifies the total chilled water plant energy usage, including each subsystem, to provide an accurate report of total energy usage before and after implementation.


Gain Transparency with Navigator

Navigator is Siemens’ cloud-based data management platform designed to help you optimize the performance of your buildings. When paired with Demand Flow for Chilled Water Systems and/or Variable Air Volume Systems, you gain the ability to monitor the long-term performance of your HVAC system by tracking, maintaining, and enhancing improvement measures. Very customizable, Navigator allows you to achieve your energy, sustainability, and system performance targets.
