Buildings must now learn from the data they produce

Imperial's Department of Civil and Environmental Engineering, Venturous Group and Neuron Digital are exploring how intelligent building technologies can make buildings more efficient, resilient and sustainable. The initiative brings academic research, smart building platforms and urban innovation expertise into one collaboration, with an initial focus on AI, digital twins, sensing systems and building performance during climate stress, including extreme heat.

The timing is important. Buildings and construction account for around 34 percent of global CO2 emissions and 32 percent of global energy demand. At the same time, heatwaves and rising temperatures are putting more pressure on cooling systems, electricity networks, building envelopes and urban infrastructure. This means the building of the future cannot only be designed well on day one. It must also operate intelligently throughout its life.

A smart building is not simply a building with many sensors. It is a connected system where heating, cooling, ventilation, lighting, shading, access control and safety systems can exchange data and respond to real conditions.

The Internet of Things provides the sensing layer. Sensors collect information on occupancy, temperature, air quality, energy use and equipment performance. Actuators then convert control decisions into physical actions, such as adjusting ventilation, lighting or shading.

The digital twin provides the operational layer. It represents the building, its systems and its processes in digital form, allowing current and historic data to be linked. This makes it easier to understand why a building is using energy, where performance is drifting and which interventions could improve comfort, cost and emissions.

AI adds another level by identifying trends that are difficult to see manually. It can help predict demand, detect abnormal system behaviour, optimise cooling strategies and support faster decisions in complex operating conditions.

The Imperial initiative is expected to use living labs, meaning real buildings where researchers and industry partners can test technologies in operational settings. This matters because building performance is highly dependent on real use. Occupant behaviour, weather, equipment age, maintenance and control settings can all change the result.

The building is no longer only a structure, envelope and services package. It becomes a monitored asset that can be tuned, tested and improved over time.

The challenge is to make these systems commercially attractive, technically reliable and socially useful. Smart buildings must reduce energy demand, improve resilience and maintain user comfort without becoming overly complex or difficult to manage.

If successful, collaborations like this could help move the built environment away from static design assumptions and toward adaptive operation, positioning intelligent buildings as practical tools for climate resilience, energy efficiency and healthier urban living.
