How Open Protocols An Digital Twins Are Shaping Building Automation

Modern buildings are more connected and intelligent than ever before, thanks to the steady evolution of building management technology. Over time, the industry has moved far beyond simple control panels and limited integration. Today’s smart infrastructure relies on advanced digital platforms that coordinate heating, cooling, lighting, security, and other essential systems in real time. 

This transformation has been fueled by a variety of technological breakthroughs, but one advancement stands out: open protocols and interoperability. According to a recent industry poll, open protocols and interoperability captured 41% of the vote as the most significant development. Other key innovations, including IoT integration, digital twins, and remote access, also emerged as essential trends, highlighting the increasingly connected world of building technology. 

While each of these advancements has made a substantial impact, open protocols and interoperability continue to be the backbone of progress, enabling smarter, more efficient, and more adaptable buildings. 

The evolution of building management technology 

In the past, building automation systems were typically designed as closed platforms, tightly linked to a single vendor’s proprietary hardware and software. This vendor lock-in created obstacles for building owners and facility managers, including high maintenance costs, limited flexibility, and slow adoption of new technologies. Systems were challenging to scale or upgrade, leaving operators dependent on a single supplier for support. 

This lack of flexibility slowed innovation, making it harder for buildings to adapt to emerging technologies and shifting operational needs. 

Open protocols leading the way 

The introduction of open protocols has revolutionised building technology by enabling seamless communication between devices from different manufacturers. Standards like BACnet, Modbus, and KNX have created a more competitive and innovative environment. 

Scalability is a major advantage of open protocols. As buildings evolve, facility managers can incorporate new devices and systems without worrying about compatibility. This futureproofing ensures that investments made today remain relevant as technology advances, whether that means adding renewable energy sources, enhancing lighting controls, or expanding safety features. 

Cost efficiency is another key benefit. Competitive bidding for components, software, and maintenance reduces overall lifecycle costs. Building owners are no longer tied to a single vendor’s pricing, giving them the freedom to negotiate better terms and select solutions that meet their specific needs. 

IoT integration in smart buildings 

Open protocols provide the foundation, but IoT integration truly elevates building automation. IoT devices and sensors gather data at scale, offering real-time insights into building performance. This information allows facility managers to monitor and optimise energy use, ensuring systems operate effectively and sustainably. 

Predictive maintenance is one of the most valuable uses of IoT, enabling operators to anticipate and address equipment failures before they occur. This proactive approach reduces downtime and extends the life of critical systems. 

Additionally, IoT improves occupant comfort by enabling personalised controls that adapt to individual preferences and occupancy patterns. Smart systems can adjust temperature, lighting, and air quality to create a more comfortable and productive environment, enhancing tenant satisfaction and employee well-being. 

Digital twin technology 

Built on the wealth of data provided by IoT, digital twins create detailed digital representations of physical assets or systems. Updated continuously with real-time information, they allow operators to simulate and test changes without disrupting daily operations. This flexibility is invaluable for exploring energy-saving strategies, evaluating equipment upgrades, and optimising building layouts. 

Digital twins also enable proactive maintenance by identifying issues before they become serious, reducing the risk of costly failures. They bridge the gap between design, construction, and operation, ensuring that insights gained at each stage of a building’s lifecycle inform future decisions. This ongoing flow of knowledge results in better performance and lower overall costs. 

Remote access enhances efficiency 

The COVID-19 pandemic highlighted the importance of remote access. With secure connectivity, operators can monitor and control systems from anywhere, staying updated on alarms, performance, and energy use without needing to be on-site. This capability reduces travel needs, saving time and expenses while ensuring continuous operation. 

Remote access also enables engineers and technicians to troubleshoot and configure equipment off-site. This flexibility is especially valuable when in-person presence is limited. It enhances safety by reducing the need for on-site staff during health crises or emergencies. 

Integrating open protocols, IoT, digital twins, and remote access 

The combination of open protocols, IoT integration, digital twins, and remote access has reshaped the landscape of building management. Open standards remain central to this transformation, ensuring that these technologies work together seamlessly. Without them, the benefits of IoT, digital twins, and remote access would be limited to isolated ecosystems, restricting innovation and scalability. 

Open protocols have democratised building automation by giving facility managers the freedom to choose the best solutions and integrate them effortlessly. This openness has driven the adoption of cutting-edge technologies, transforming buildings into responsive, efficient, and comfortable spaces. 

Building technology talent 

As building technology continues to evolve, the demand for skilled professionals who can design, implement, and manage these systems is growing rapidly. The integration of open protocols, IoT, digital twins, and remote access requires a workforce that is both technically adept and adaptable. 

Toby Northfield, Head of Building Automation & Data Center Controls Engineering, explains: 

As systems become more interconnected and technologies like IoT and digital twins become standard, the complexity of projects is increasing. It’s no longer enough to have professionals who specialise in one area; we need people who can bridge disciplines—who can think holistically about systems integration, cybersecurity, and user experience. The most effective projects are led by teams that thrive on collaboration, creativity, and the ability to see the bigger picture. As technology evolves, the human element is what ensures that innovations translate into real-world impact.
