In this episode of the Data Center Frontier Show podcast, we sit down with Martin Renkis, Executive Director of Global Alliances for Sustainable Infrastructure at Johnson Controls, to explore how Data Center Cooling as a Service (DCCaaS) is changing the way operators think about risk, capital, and sustainability.

Johnson Controls has delivered guaranteed infrastructure services for over 40 years, shifting cooling from a CAPEX burden to an OPEX model. The company designs, builds, operates, and maintains systems under long-term agreements that transfer performance risk away from the operator.

Key to the model is AI-driven optimization through platforms like OpenBlue, paired with financial guarantees tied directly to customer-defined KPIs. A joint venture with Apollo Group (Ionic Blue) also provides flexible financing, freeing up capital for land or expansion.

With rising rack densities and unpredictable AI factory demands, Renkis says cooling-as-a-service offers “a financially guaranteed safety net” that adapts to change while advancing sustainability goals.

Listen now to learn how Johnson Controls is redefining cooling for the AI era.

As AI workloads reshape the data center landscape, speed to power has overtaken sustainability as the top customer demand. On this episode of the Data Center Frontier Show, Editor-in-Chief Matt Vincent talks with Brian Melka, CEO of Rehlko (formerly Kohler Energy), about how the century-old power company is helping operators scale fast, stay reliable, and meet evolving energy challenges.

Melka shares how Rehlko is quadrupling production, expanding its in-house EPC capabilities, and rolling out modular power blocks through its Wilmott/Wiltech acquisition to accelerate deployments and system integration. The discussion also covers the balance between diesel reliability and greener alternatives like HVO fuel, hybrid power systems that combine batteries and engines, and strategies for managing noise, emissions, and footprint in urban sites.

From rooftop generator farms in Paris to 100MW hyperscale builds, Rehlko positions itself as a technology-agnostic partner for the AI era. Listen now to learn how the company is helping the data center industry move faster, smarter, and more sustainably.

Smarter Security Starts with Key & Equipment Management In data centers, physical access control is just as critical as cybersecurity. Intelligent key and equipment management solutions help safeguard infrastructure, reduce risk, and improve efficiency — all while supporting compliance.

Key Benefits:

• Enhanced Security – Restrict access to authorized personnel only
• Audit Trails – Track every access event for full accountability
• Operational Efficiency – Eliminate manual tracking and delays
• Risk Reduction – Prevent loss, misuse, or unauthorized access
• System Integration – Connect with access, video, and visitor tools
• Regulatory Support – Comply with ISO 27001, SOC 2, HIPAA & more

A smart solution for a high-stakes environment — because in the data center world, every detail matters.
