Deployment Challenges Exist: Legacy systems, sensor calibration issues, and limited access to skilled professionals can complicate implementation—but can be overcome with planning.
For many smart building owners, a digital twin is not just a buzzword but a proven technology that has demonstrated tremendous value in the short time it has been available. The creation of virtual replicas of physical assets, fueled by real-time data and artificial intelligence to perform advanced analytics, is becoming increasingly sophisticated and accurate. In fact, a recent Digital Twin Industry Report from Hexagon shows that 62% of respondents claim “immense value” from their digital twin initiatives.
How are these companies deriving such value? Let’s examine a couple of relatable smart building use cases illustrating how digital twins enhance efficiency through predictive maintenance and energy modeling within typical smart buildings.
Use Case 1: Predictive Maintenance in a Class-A Office Building
Our first use case example is a Class-A office tower, where building operators implement a digital twin to monitor critical systems like heating, air conditioning components, and elevators. With the help of a network of IoT sensors, the digital twin collects real-time data on equipment performance, looking for changes in baseline behavior, including aspects such as motor vibrations, temperature fluctuations, and humidity spikes.
AI analytics is used to predict potential failures, anticipate when failures will occur, and offer guidance on precisely what maintenance needs to be performed. This type of proactive and intelligent modeling has the potential to eliminate major outages and to identify and remediate small mechanical faults at a lower cost compared to waiting until these small issues turn into much larger (and costlier) incidents.
Use Case 2: Energy Modeling in a Mixed-Use Retail Complex
A second relatable use case involves a mixed-use retail complex that includes retail shops, offices, and restaurants. Here, building operators deploy a digital twin to optimize energy consumption across the diverse tenants. The digital twin aggregates data from smart meters and occupancy sensors and collects real-time weather forecast data from the internet to model energy usage across smart lighting, HVAC, and escalator management platforms. By simulating hundreds of different scenarios within the digital twin, operators learn that adjusting HVAC settings during low-occupancy evening hours significantly reduces energy waste, aiding compliance with local and state regulations and lowering operating costs.
Digital Twin Challenges and Considerations
While digital twins deliver clear benefits, it must be pointed out that smart building owners, operators, and integrators face adoption challenges. For predictive maintenance use case examples, integrating IoT sensors with legacy systems can end up being a complex process, often requiring more time than anticipated, along with significant investments that likely were not initially accounted for. Additionally, poor data quality, such as inaccurate or mis-calibrated sensors, can unintentionally skew AI predictions, leading to tedious troubleshooting and manual adjustments.
As for energy modeling use cases, challenges can occur when attempting to build baseline models that are accurate. Doing so requires high-quality historical data over a sustained period of time, which older buildings and IT/OT equipment may struggle with.
It’s also important to note that smart building digital twins are still a relatively new concept for building operators and integrators. Thus, a seamless digital twin deployment requires finding the right skillset. This can be a scarce resource depending on the market or geographical location.
That said, with the right planning, coordination and patience, these challenges can be overcome, giving building owners the ability to harness digital twins for smarter, more efficient operations.
Conclusion
Despite some remaining early-adoption hurdles to overcome, digital twins are transforming smart buildings, further driving cost, resource, and energy efficiencies through predictive maintenance and energy modeling. From preventing costly HVAC and elevator failures in our Class-A office building to cutting energy usage and costs in mixed-use retail complexes, these virtual replicas enable data-driven management. As long as integration issues, data quality, and strategic planning are conducted with trained professionals who have experience with digital twin technologies, significant smart building operations have significant potential.
