If you’re still treating your building systems as a facilities challenge, you’re managing last decade’s data center. Today, building automation is no longer just a behind-the-scenes tool for keeping lights on and rooms cool — it has become a strategic component of operational resilience, cost control, and sustainability. For data centers, this transformation is particularly evident, as uptime requirements, energy usage, and system complexity have all climbed. At the heart of this shift is the growing role of IT in driving, managing, and even designing the building systems that once belonged solely to facilities.
The convergence of IT and building automation is no longer experimental — it’s operational. This isn’t just a trend anymore. It’s table stakes. Data center operators now rely on software-defined infrastructure that treats HVAC, power, and security systems as nodes in a network. These systems are IP-based, built around open protocols, and integrated through centralized platforms that provide real-time visibility and control. That visibility means operators can act more quickly and decisively, before thresholds are breached, or equipment begins trending out of spec.
At many facilities, these platforms are no longer run exclusively by facilities teams. IT departments now play a direct role in evaluating BAS software, setting up system integrations, and managing data storage and security. This makes sense: modern building automation shares more common with network monitoring tools than with old-school thermostats or breaker panels. The data volume is significant, the architecture is digital, and cybersecurity is a very real concern.
Ascent has observed firsthand how organizations are approaching this shift. More operators are requesting unified platforms that allow users to monitor power, cooling, fire systems, and access control from a single interface — ideally one that’s mobile-accessible and scalable across multiple sites. These platforms are expected to provide alerting, trending, reporting, and analytics capabilities. They’re also expected to integrate with enterprise tools, from ticketing systems to cloud-based data storage.
But the infrastructure side of things has also shifted. Structured cabling and IP addressing must be coordinated with corporate standards. System uptime is measured in IT terms — “five nines” availability — and that expectation now applies to the chiller, the UPS and the fire systems, not just servers.
However, this evolution isn’t without its growing pains. Cultural differences between IT and data center facilities can still create friction. But the benefits are clear: improved monitoring, faster response times, greater energy efficiency and a more agile operating model that can adapt as compute requirements change.
The result is an environment that’s not only more intelligent, but more aligned — one where IT and facilities speak a common language, share a common platform and contribute to a common mission: delivering reliable, scalable, efficient infrastructure.
With IT now embedded in building automation platforms, the data center has become smarter, faster, and more integrated than ever. But the future promises even more: predictive systems, AI-driven insights, and fully virtualized automation. Stay tuned for the final post in the series: what’s next for IT-driven facilities.
