Johnson Controls Brings Data Center Cooling into the “As-a-Service” Era

Cooling Without the Risk

Johnson Controls’ Data Center Cooling as a Service (DCCaaS) approach is designed to take cooling risk off the operator’s shoulders. The company doesn’t just provide the technology—it delivers a comprehensive, long-term service package that covers design, build, operation, maintenance, and life cycle management.

The model shifts cooling from a capital expense to an operating expense, providing financial flexibility at a time when operators are pouring billions into AI-ready infrastructure. “We take on the risk of performance and uptime,” Renkis explained. “If we don’t meet the agreed-upon KPIs, there are financial consequences for us—not the customer.”

The AI Advantage

A key differentiator in Johnson Controls’ approach is its integration of AI, machine learning, and advanced analytics. Through its OpenBlue and Metasys platforms—supplemented by partnerships with three to four external AI providers—the company is able to continuously optimize cooling system performance.

These AI-driven systems not only extend the life of equipment but also deliver financially guaranteed outcomes. “We tie our results to customer-defined KPIs,” said Renkis. “If we miss, we pay. That accountability drives everything we do.”

Modularity with Flexibility

While the industry is trending toward modularity and prefabricated builds, Renkis stressed that every DCCaaS project remains unique. Johnson Controls designs contracts with “detour functionality”—flexible pathways to upgrade and adapt as technology shifts.

That flexibility is crucial given the rapid emergence of AI factory-scale demands. New chip architectures and ultra-dense racks—600kW, 1MW, even 1.5MW—are reshaping expectations for cooling and power. “Nobody knows exactly how this will evolve,” Renkis noted. “That uncertainty makes the as-a-service model the most prudent path forward.”

Beyond Traditional Facilities Management

Cooling-as-a-service is distinct from conventional facilities management in both scope and financial muscle. Johnson Controls brings to the table its own capital arm—Johnson Controls Capital—and a joint venture with Apollo Group, known as Ionic Blue, that enables a spectrum of financing models. Options include operating and finance leases, asset-backed loans, and off-balance sheet structures.

The financial guarantees are equally robust. Johnson Controls reports a 99.98% success rate in delivering on its financially guaranteed services across 40 years, underpinned by monthly transparency reports and strict adherence to uptime and life cycle KPIs.

Sustainability at the Core

Cooling isn’t just an operational concern—it’s an environmental one. Roughly 40% of global carbon emissions originate from buildings, with cooling playing a major role. Johnson Controls is investing heavily in R&D through a dedicated Center of Excellence and deploying more than 1,000 sustainability experts to help customers cut water and energy use, exceed ESG targets, and unlock carbon credits.

“Cooling is a front line in the battle against emissions,” Renkis said. “We’re designing systems that are not only reliable, but also built for a decarbonized future.”

The Ownership Question

Interestingly, Johnson Controls itself typically does not own the cooling systems in a DCCaaS arrangement. Instead, ownership is placed in a special purpose vehicle (SPV) created by a financing partner. The operator pays that third-party owner, who in turn pays Johnson Controls for services. This structure allows data centers to avoid direct liability for environmental, noise, or other operational issues tied to the equipment.

The Broader “As-a-Service” Trend

The move toward infrastructure-as-a-service is gaining traction industry-wide. Drivers include capital constraints, labor shortages, deferred maintenance, and tightening decarbonization mandates. Cooling is Johnson Controls’ initial focus, but Renkis sees the potential for a broader wave of infrastructure offerings.

For now, the emphasis is on scale and reliability. As operators grapple with unknowns around AI infrastructure, cooling-as-a-service provides what Renkis calls “a financially guaranteed safety net”—a way to meet today’s urgent demands without overcommitting capital or assuming unmanageable risks.

A Strategic Shift for the AI Era

At its core, DCCaaS eliminates risk, optimizes cost, and unlocks financial flexibility. By transferring ownership and performance responsibility away from operators, Johnson Controls enables customers to focus on their core business—scaling data center capacity for the AI-driven future.

“Cooling is critical to sustainability, uptime, and financial performance,” Renkis concluded. “Our job is to take on that responsibility so operators can focus on what’s next.”
