Every Monday, industry leaders and innovators gather for MondayLive!, an interactive session dedicated to navigating the future of smarter buildings and intelligent infrastructure. They delve deeply into the technologies, strategies, and big ideas that shape our industry. Join the conversation and help us compose what’s next.
Ever feel like the concept of a “Digital Twin” has become a modern-day bogeyman for the built environment? A complex, all-seeing, all-knowing digital monster that’s expensive to create and even more costly to maintain?
A recent industry roundtable offered a powerful antidote to this fear, reframing the digital twin not as a single terrifying entity, but as a harmonious, composable system. The conversation moved beyond the hype to deliver a practical and liberating message:
Your path to a smarter building isn’t about building a monster; it’s about conducting an orchestra.
Here are a few key insights
1. The “Aha!” Moment: It’s Twins, Not Twin
The most powerful shift in thinking came from a simple change in vocabulary. One panelist cut to the heart of the issue, stating:
“We need to be deliberate to use the plural ‘twins’ and never use the singular.”
This isn’t just semantics. Using the plural “twins” shatters the illusion of a single, monolithic system. It acknowledges a fundamental truth: a building is a complex ecosystem. You don’t have one twin; you have a dynamic collection of them—a digital twin for an HVAC system, another for occupancy tracking, another for energy grid interaction, and more. The magic happens when these specialized, purpose-built twins are composed to work together.
This composable approach makes digital twins accessible. You don’t need to boil the ocean. You can start with a single, high-value use case, such as optimizing a chiller plant or simulating airflow in a critical space, and build from there.
2. The Ultimate Clarifier: It’s a Program, Not a Product
A second major insight emerged to dispel another common myth: that a digital twin is a product that can be purchased off the shelf. The panel was clear on this point. A digital twin is not a shrink-wrapped software suite. As one expert clarified:
“It’s a collection of capabilities, not a single product you install.”
Thinking of it as a “collection of capabilities” is liberating. It means you likely already have the foundations in place—your building management system, your data historians, your BIM models. The journey involves architecting existing capabilities and adding new ones to enable synchronization and intelligence. The ultimate goal, as another voice succinctly put it, is to “get to the damn data.” If you can achieve open, accessible data that flows across traditional silos, you are well on your way.
3. The Killer App: Unleashing the Power of Simulation
So, what’s the ultimate payoff for composing your digital twins? The panel pointed to one area with immense ROI: simulation.
This is where the digital ecosystem truly shines. With a composable model, you can run “what-if” scenarios in a risk-free digital environment. What happens if we change the setpoints across an entire floor? How does a new piece of equipment impact energy load? Can we simulate emergency evacuation routes? By testing in the digital realm, you can optimize performance, predict outcomes, and make smarter decisions without ever touching the physical asset.
Your Takeaway: Start Composing, Not Building
The collective wisdom from the discussion provides a clear and actionable roadmap:
- Start with a Use Case, Not a Technology: Identify a specific business problem—energy, maintenance, tenant experience—and let that guide your first step.
- Think Plural: Plan for a team of specialized, interoperable digital twins, not a single, all-powerful one.
- Focus on Data Flow: Prioritize unlocking and standardizing your data above all else. This is the bedrock of composition.
- Aim for Simulation: Keep the high-value goal of predictive modeling and scenario testing in sight as your ultimate competitive advantage.
By letting go of the monolithic monster, we can embrace a future where digital twins are practical, powerful, and profoundly helpful. Stop building the beast and start conducting your digital symphony.
