Energy Wins with Digital Twins

In a world obsessed with sequels-Avengers: Endgame, Top Gun: Maverick, Stranger Things-the idea of a ‘twin’ conjures something familiar yet evolved. Now, imagine if buildings had sequels too-not in bricks and steel, but in data. That’s exactly what digital twins are. And in the race to combat climate change, improve efficiency and manage costs, they might just be the superheroes the built environment has been waiting for.

What Is a Digital Twin?

A digital twin is a virtual replica of a real-world object or space that’s synced with the physical world via sensors, IoT devices or smart systems. This connection allows it to receive live data, simulate future scenarios and support predictive decisions. Think of it as the FitBit of buildings-constantly monitoring, analysing and optimising performance in real time.

For buildings, this means a digital version that includes all physical elements-walls, windows, HVAC systems, lighting, elevators, sensors and even the people who interact with them. When integrated into platforms such as Autodesk Tandem, digital twins become intelligent tools that help design, maintain and operate buildings more efficiently.

Working in Tandem

Autodesk Tandem for AEC transforms Revit and BIM data into a comprehensive digital twin. From visualising mechanical systems and measuring design performance post-handover to tagging and tracking assets, Tandem is part of the digital twin software matrix that bridges the gap between design intent and real-world operation. Its key features include:

The Energy Equation

Buildings account for approximately 36% of global emissions, with the majority coming from outdated and inefficient infrastructure. A staggering portion of Europe’s building stock was built before 2001, offering a massive opportunity for sustainable retrofits. Digital twins can address this by:

From temperature and lighting automation to integrating solar and geothermal energy, digital twins enable buildings to shift from reactive to intelligent renewable energy systems.

Real-World Wins: Energy Efficiency

Multiple studies and real-life applications have demonstrated the value of digital twins and energy system models in energy savings and operational efficiency:

BIM + IoT = A Well-suited Pair

While BIM (Building Information Modelling) provides detailed structural data, it’s largely static. Enter IoT-real-time sensors that capture what’s actually happening inside the building. Together, they offer a complete picture: design + performance. The result? Intelligent building management systems that can self-learn, self-regulate and forecast demand. For instance, smart facades equipped with sensor networks can monitor temperature, humidity and light exposure and transfer this data to digital twins for more effective insulation strategies or trigger cooling systems before occupants feel the heat.

AI, Automation & Beyond

Digital twin technology and virtual energy systems are still evolving. The next frontier lies in integrating AI and machine learning to forecast load behavior, automate control systems and manage energy supply in real time-especially when connected to smart grids and EV infrastructure.

Research suggests that in the future, digital twins for energy systems could operate Energy Operation Centres (EOCs) where managers can monitor and control all building systems centrally, reducing manual oversight and management overhead.

Smart & Strategic

In a climate-conscious world where both carbon footprints and energy bills matter, digital twin technology offers a powerful, actionable solution for environmental sustainability. More than just a digital mirror, digital twins are a decision-making double engine, helping building owners, designers and operators turn insight into impact.

So, while Batman has the Batcave and the Batmobile and Iron Man has Jarvis and the Suit, the buildings of the future have digital twins- a win for energy, the environment and the economy.
