The reason is simple: their data is not accessible.

In many existing facilities today, data is trapped. It lives inside proprietary systems, vendor-specific platforms and aging hardware. It is fragmented, inaccessible and difficult to use. Until that changes, ever-advancing technology will not be able to reach it.

Before buildings can truly get smarter, their data must be liberated.

Get the Data Out of the Building

Many buildings are tightly bound to a single vendor’s ecosystem with limited paths leading in or out. Controls, analytics and reporting tools are often designed to work best, or only, within that closed environment.

Vendor lock-in makes it harder to adopt new tools and increases costs over time. It also slows innovation, because every new capability depends on one provider’s roadmap. At the same time, building systems are tied to hardware that operates on much longer lifecycle timelines. While software evolves rapidly, control systems and equipment are often expected to remain in place for decades. That mismatch makes it difficult to take advantage of new capabilities as they emerge. 

Liberating data reduces that dependency and helps break the link between software capabilities and hardware constraints. When data is accessible outside a proprietary system, interoperability becomes possible. Owners and operators gain the freedom to choose a combination of tools based on value, not compatibility.

Once the data is accessible, the next step is to bring it together. A single building generates data from HVAC systems, energy meters, controls and other subsystems. On top of that, there are external data sources such as weather, utility pricing and occupancy patterns.

Individually, each of these gives information, but together, they can tell a story.

This becomes even more important as building operations scale. Trying to manage an entire campus without a way to standardize and aggregate data across the environment makes it very difficult to identify trends or apply consistent strategies or remedies.

In practice, this does not require replacing every system in a building. You can start by extracting data from existing systems using standard protocols or built-in system integrations, then consolidating it into a centralized environment where it can be normalized and accessed. From there, additional data sources can be layered in over time, creating a more complete and usable picture of building performance.

Managing Trade-Offs in Real Time

Every operational decision in a building involves trade-offs. Energy efficiency versus occupant comfort. Maintenance costs versus system performance. Short-term savings versus long-term reliability.

Too often, these decisions are made with incomplete or disconnected information. Teams rely on experience and intuition because the data needed to evaluate options side by side is not readily available.

When data is centralized and visible in a single interface, those trade-offs become much easier to manage. You can evaluate competing priorities side by side. You can see how one adjustment impacts another.

You’ll be able to make better decisions faster, with less uncertainty and waste.

Operating in a Changing Environment

Buildings do not operate in a static world. Energy prices fluctuate due to global events, regulations change, weather becomes more volatile and occupancy patterns can shift.

For example, a sudden spike in energy prices can significantly impact operating costs. Without visibility into system performance and usage patterns, there is little opportunity to respond by rebalancing priorities.

With accessible data, teams can identify changes early and adjust operations accordingly. This is where modern tools begin to deliver real value.

Preparing for Tomorrow’s Technology

• Today’s technological landscape offers many capabilities above and beyond building control, such as advanced analytics and data visualization
• Fault detection and diagnostics
• Trend identification across systems
• AI-assisted diagnostics and root cause analysis
• Web-based and mobile access to building data

The common requirement for all these tools is access to data. Without it, they cannot function. With it, they become powerful and build on each other.

Looking forward, the next wave of capability will build on that same foundation.

We are already seeing early versions of systems that can interact with building data in more dynamic ways. Agent-based approaches are emerging, where software can interpret data, suggest actions and eventually execute them. Control strategies are becoming more responsive and adaptive. Interfaces are becoming more intuitive, including the ability to interact with or modify systems using natural language.

The feasibility of that future depends on how data is structured and accessed today.

The Data Layer: The Foundation for Everything

Extracting data from systems is only the first step. Raw data on its own has limited value.

To become information, data must be organized and structured. A functional data layer provides context across systems, standardizes information and allows software to understand how different elements relate to one another.

In practice, this often takes the form of a centralized data layer that organizes and contextualizes information across a facility or portfolio. At Harris, our Telemetry platform is designed to do exactly this. It aggregates data from across systems and makes it accessible and readable through a single interface so it can be used for analysis, diagnostics and decision-making.

This approach is often implemented incrementally, starting with a subset of systems and expanding over time as more data is integrated.

The difference is significant. Raw data only tells you what happened. Structured data helps you understand why it happened and what to do next.

From Data Insights to Action

Once data is accessible and structured, the progression is clear.

Data leads to insight. Insight supports better decisions. With the right foundation, those decisions can be continuously reevaluated, and the resulting lessons learned can be applied in the future. As technology continues to improve, systems will increasingly recommend those actions, automate responses and continuously optimize performance in the background.

This shift has implications beyond operations. It should influence how buildings are designed in the first place.

Data accessibility should never be an afterthought in the design process. It should be discussed early and written into specifications. When that happens, systems are implemented in a way that supports long-term performance instead of creating constraints that have to be worked around later.

Forward-thinking organizations are already moving in this direction.

They are prioritizing data accessibility and centralizing building information. They are connecting legacy systems to modern tools instead of replacing everything at once.

At Harris, our Telemetry platform is used to centralize building data into a single, accessible view, making it easier to analyze performance and respond in real time. This gives owners, operators, technicians and project teams a clearer understanding of how their facilities are operating and allows them to make more informed decisions over time.

The Real Competitive Advantage

Building performance will not be defined by adding more hardware or layering on new tools.

It comes down to having access to the right data, at the right time, and being able to use it effectively.

Organizations that prioritize data accessibility today will be in a much stronger position to adapt as technology continues to evolve. They will be able to respond to change more quickly, make more informed decisions and take advantage of new capabilities as they emerge.

That foundation, not any single platform or device, ultimately determines whether a building can truly become smart.

You may not be able to future-proof the equipment in your building, but you can future-proof your data.
