(Johnson Controls: Milwaukee) -- Johnson Controls, a global leader in smart, healthy, and sustainable buildings, announced the launch of its Reference Design Guide Series for 1 Gigawatt AI data centers. Each guide in the series maps the full thermal chain, offering cooling architectures tailored to diverse compute densities, geographies, and elevations. The series begins with a detailed blueprint for water-cooled chiller plants. Future guides will address air-cooled and absorption chiller solutions.

As AI transforms industries, the scale and complexity of data center infrastructure is rapidly evolving. The ability to efficiently manage thermal loads at gigawatt scale is now a critical enabler for AI innovation, and the industry faces mounting pressure to deliver facilities that are not only high-performing but also sustainable and future-ready. Johnson Controls’ Reference Design Guide Series responds to this challenge by outlining how to achieve industry-leading energy and water efficiency (PUE and WUE) while maintaining flexibility to scale across diverse climates and operational requirements.
