In recent years, smart buildings have become a key element in the transformation of cities and the move towards a more sustainable and efficient society. These buildings combine the integration of digital technologies, automation, and connectivity to respond to increasingly demanding energy, environmental, and urban management challenges.
The commitment to digitalization and smart control in the building sector allows for greater operational efficiency and enables us to address challenges such as decarbonization, reduced energy consumption, and improved quality of life in urban environments. Specialized companies, research centers, and public administrations are working together to make this paradigm shift a reality.
Digital tools for a more efficient real estate portfolio
The European Union's Digital Building Model (DBSM) has become one of the most cutting-edge resources for analyzing Europe's building stock. With a structure based on geospatial and energy data, it allows for precise assessments of building use, height, age, and energy efficiency across the 27 member states.
Developed by the European Commission's Joint Research Centre, the DBSM allows for the study of key aspects such as energy consumption , the deployment of renewable infrastructure, risk management, and urban policy planning with a solid empirical foundation. The latest version, R2025, integrates information from satellite imagery, official databases, and recognized sources such as OpenStreetMap and Eubucco, achieving high resolution and reliability.
Thanks to its open nature , both public bodies and private agents can access the information, which facilitates everything from rehabilitation strategies to comparisons between different regions.
Automation and efficiency in building renovation
The momentum behind initiatives like the Renomize project highlights the importance of industrializing and automating deep energy retrofit processes. This initiative, with the participation of leading centers such as Tecnalia, is committed to developing advanced automation systems, robotics, and production methods to modernize Europe's building stock.
Key advantages include significant cost and time reductions , as well as enhanced workplace safety through the introduction of robotic technologies and automated processes. Furthermore, construction solutions are being designed and validated to improve fire performance while ensuring sustainability, efficiency, and protection.
This work ranges from factory optimization to on-site installation, incorporating decision-support tools for selecting HVAC technologies, renewable energy, and space-time planning.
Materials innovation: self-regulating cement and bio-inspired solutions
The pursuit of greater efficiency in smart buildings also involves the development of innovative materials . A prime example is the new cement developed by researchers at Drexel University, which incorporates an internal network of paraffin-filled channels. This material, inspired by natural thermal regulation mechanisms found in animals such as elephants and rabbits, allows building surfaces to passively regulate their temperature .
The use of phase-change materials within cement provides a gradual cooling or heating effect depending on ambient conditions, thereby reducing dependence on conventional air conditioning systems and lowering energy consumption.
Initial studies confirm that the design of these channels, especially the diamond shape, achieves an excellent combination of structural strength and thermal efficiency, accelerating the transition toward more sustainable and intelligent buildings.
Intelligent control platforms and technology parks in urban environments are demonstrating the potential of innovative solutions for managing large infrastructures. One example is Sevilla TechPark , which promotes the implementation of digital twins to simulate scenarios, anticipate risks, and automate responses to events and emergencies.
The integration of open data platforms and interoperable systems enables real-time management of building operations, resource monitoring, increased efficiency, and facilitated strategic decision-making. With multimillion-euro investments and the support of public administration, these projects pave the way for smart, sustainable, and self-sufficient buildings, aligned with European decarbonization goals.
Advances in technologies such as cloud computing, 5G, and artificial intelligence reinforce this trend, enabling the connection of sensors, communication systems, and analysis platforms to create increasingly adaptable and resilient environments.
With all these advances in automation, digitalization, and innovative materials, smart buildings are consolidating their position as key players in the creation of more sustainable, comfortable, and safe cities, where buildings actively participate in the transformation toward a green and connected future.
