Managing healthcare infrastructure requires balancing patient care with strict environmental responsibilities. In the UK, the National Health Service faces a complex challenge: modernizing aging facilities to meet aggressive net-zero carbon targets without disrupting critical medical services. Addressing this need, Edinburgh Napier University is spearheading new research into digital twin technology to develop sustainable hospitals capable of withstanding future climate disruptions. By creating precise virtual models of physical healthcare estates, researchers are providing facility managers and policymakers with the data required to make informed, cost-effective decarbonization decisions.

The Need for Sustainable Hospitals in the UK Healthcare System
The UK healthcare sector is inherently resource-intensive. Hospitals operate continuously, requiring massive amounts of energy for heating, ventilation, air conditioning (HVAC), lighting, and powering advanced medical equipment. Consequently, healthcare facilities account for a significant portion of the nation’s public sector carbon footprint. To combat this, the NHS Scotland Climate Emergency and Sustainability Strategy outlines ambitious targets to reduce emissions and adapt to the realities of climate change.
Meeting these targets requires moving beyond basic energy efficiency measures. Facility managers must implement comprehensive decarbonization strategies that account for the unique operational constraints of clinical environments. For example, operating theaters require strict air change rates and temperature controls that limit traditional energy-saving methods. Furthermore, as extreme weather events become more frequent, healthcare infrastructure must adapt to remain operational during heatwaves, flooding, and severe winter storms. Creating truly sustainable hospitals in the UK demands a systemic approach that evaluates entire estates rather than isolated buildings.
NHS Greater Glasgow and Clyde (NHSGGC), the largest health board in Scotland, illustrates the scale of this challenge. The board serves approximately 1.3 million people across a vast network that includes 23 hospitals, nine acute sites, and more than 70 health centers and clinics. Upgrading and decarbonizing an estate of this magnitude requires precise planning, significant capital investment, and a clear understanding of how various interventions will interact across different facility types.
Applying Digital Twin Technology to Healthcare Estates
To address these complexities, researchers at Edinburgh Napier University are utilizing digital twin technology. A digital twin is a highly detailed virtual representation of a physical asset, system, or process. In the context of healthcare infrastructure, it involves creating a dynamic, real-time digital replica of a hospital or an entire health board’s estate. This replica is continuously updated using operational, energy, and environmental data collected from sensors and building management systems.
Professor Berk Canberk, Head of Cyber Security & Systems Engineering at Edinburgh Napier University, leads the initiative. The research focuses on integrating disparate data streams—ranging from real-time energy consumption metrics to historical weather patterns—into a unified digital environment. By building a real-time replica of a hospital estate, administrators can visualize current performance and run complex simulations to test future scenarios.
For instance, before investing in a large-scale solar array or a district heating network, facility managers can use the digital twin to model the technology’s impact on the hospital’s energy grid. They can observe how the new systems perform during peak demand, identify potential bottlenecks, and calculate the actual return on investment. This capability significantly reduces the financial risk associated with major infrastructure upgrades.

Developing a Framework for Climate-Resilient Healthcare
Reducing carbon emissions is only one aspect of the research. The project explicitly focuses on climate-resilient healthcare, ensuring that facilities can withstand and adapt to the impacts of a changing climate. Resilience in healthcare means maintaining continuous patient care even when external conditions are severe.
The Edinburgh Napier University team is developing a specialized framework designed to assess the potential impact of various climate adaptation interventions. This framework evaluates how different renewable energy technologies, building envelope improvements, and passive cooling strategies perform under projected climate scenarios. If a region is expected to experience more intense summer heatwaves, the digital twin can simulate how those temperatures will affect indoor climates and the subsequent strain on cooling systems.
By analyzing these stress tests, healthcare administrators can prioritize capital expenditures on the adaptations that offer the greatest protective value. The framework moves the conversation beyond simple compliance, providing evidence-based recommendations that support long-term strategic planning for climate-resilient healthcare.
Strategic Partnerships Driving NHS Innovation
Solving the sustainability puzzle requires interdisciplinary collaboration. Edinburgh Napier University has partnered with Glasgow Caledonian University (GCU) and NHS Greater Glasgow and Clyde to ensure the research is grounded in real-world clinical and operational realities.
This partnership bridges the gap between academic theory and practical application. GCU contributes expertise through its Healthcare Built Environment Doctoral Academy, bringing deep knowledge of how physical spaces impact patient outcomes and staff efficiency. Edinburgh Napier University contributes through the Scottish Healthcare Built Environment Network (SHBEN), providing technical prowess in systems engineering and data analytics.
Crucially, NHS Greater Glasgow and Clyde serves as the active testbed and external collaborator. By working directly with the health board’s facility management and sustainability teams, the researchers ensure that the digital twin models address actual pain points rather than theoretical assumptions. This collaborative approach accelerates the translation of research into actionable policies. Have questions?

Scaling Net-Zero Solutions Across the UK
While the initial research focuses on NHS Greater Glasgow and Clyde, the long-term objective is to create a scalable model. The challenges facing NHSGGC are mirrored by health boards and NHS trusts across the UK. If the digital twin framework proves effective in managing Scotland’s largest health board, the methodologies, algorithms, and best practices can be adapted for smaller clinics, rural hospitals, and entirely different geographic regions.
The project is one of 14 initiatives funded through the latest Scotland Beyond Net Zero (SBNZ) seed funding round. This backing underscores the national importance of developing scalable solutions for the transition to a low-carbon economy. By treating the NHS estate as a connected data ecosystem rather than a collection of isolated buildings, Edinburgh Napier University is establishing a blueprint for sustainable hospitals that can be replicated nationwide.
The Future of Healthcare Infrastructure Management
The integration of digital twin technology into healthcare estate management represents a fundamental shift in how the UK approaches public sector sustainability. Rather than relying on reactive maintenance and piecemeal upgrades, facility managers can leverage continuous data streams to make proactive, optimized decisions. This approach not only accelerates progress toward net-zero targets but also ensures that vital healthcare services remain protected against climate-related disruptions. As the research progresses, the insights generated by Edinburgh Napier University and its partners will provide a critical roadmap for building the climate-resilient healthcare infrastructure of the future.
