Johnson Controls has recently unveiled a groundbreaking series of thermal management reference design guides tailored to meet the growing demand for high-density compute infrastructure in the global market. Specifically designed to support the next generation of gigawatt-scale AI data centers, these guides aim to assist operators and developers in designing facilities capable of efficiently managing extreme thermal loads while also addressing the rising expectations for energy efficiency, water conservation, and long-term scalability.
With the continued expansion of artificial intelligence workloads in terms of size and complexity, data center infrastructure is being pushed beyond traditional design assumptions. Large AI models require unprecedented power densities, making thermal management a crucial factor in ensuring optimal performance, reliability, and cost-effectiveness. Johnson Controls’ new guide series tackles these challenges head-on by mapping out the full thermal chain for large-scale AI environments and offering modular cooling architectures tailored to different compute densities, climates, and elevations.
The first guide in the series focuses on water-cooled chiller plants and provides an in-depth blueprint for effectively managing thermal loads in facilities operating at gigawatt scale. Future editions are expected to cover air-cooled and absorption chiller solutions, expanding the applicability of the designs across a wider range of deployment scenarios. These guides, according to the company, are intended to serve as practical engineering references rather than mere conceptual frameworks, enabling organizations to expedite their planning and deployment processes.
One of the central themes of the design is sustainability, alongside performance optimization. The guide highlights a zero-water-consumption heat rejection approach utilizing dry coolers to reduce operational costs and mitigate water-related risks in regions facing scarcity or regulatory pressure. Additionally, the design emphasizes elevated condenser water temperatures, bifurcated loops, and high-lift chiller technologies to enhance power usage effectiveness and overall annualized energy efficiency.
Furthermore, the reference architecture aligns with NVIDIA’s data center system designs, enabling operators to deploy scalable, repeatable AI factory environments capable of reaching the 1-gigawatt class. This alignment is deemed critical for enterprises and hyperscalers seeking standardized approaches to building AI-ready infrastructure while retaining flexibility for future hardware generations.
As the demand for gigawatt-scale AI data centers continues to rise, Johnson Controls’ new guide series aims to cater to a diverse range of stakeholders, including data center operators, developers, engineering teams, and sustainability officers. By offering a detailed, system-level view of thermal infrastructure, the company strives to facilitate faster decision-making and more predictable outcomes as AI infrastructure scales up.
