Cyber-Physical Energy Dynamics: Custom Pathways to Community Decarbonization and NetZero                                                   

Clipping off Embodied Carbon in Sandstone Heritage Buildings

The Crichton Trust

Established in 1839 by Elizabeth Crichton as an internationally recognised centre of excellence in mental health research and care, The Crichton was considered surplus to requirements by 1980s. In 1995, the local authority took the decision, with courage and foresight, to purchase the site with the primary objective of ensuring that this important public asset was saved and sensitively developed for the good of the wider community.

The Challenge

What was the need?

The Challenge

Decarbonization pathways presents complex social-techno-economic challenges, requiring specialized knowledge for effective multi-objective optimization. The Crichton Trust operates an extensive and varied asset base, posing both challenges and opportunities in delivering lean, green, and sustainability services to the Crichton community. Currently, there are no off-the-shelf solutions for managing such a large and diverse portfolio of assets. The primary challenges addressed through the KTP project includes:

  • Operational Efficiency / Effectives (Lean/Green): The need for low-cost solutions and operational adjustments through data driven strategies.
  • Infrastructure Digitalization: The necessity of a “Digital Twin” to minimize estate upgrade costs for a decarbonized economy, particularly addressing the unique challenges of improving the building fabric of heritage and predominantly listed sandstone buildings.
  • Transition to Low-Carbon and Low-Heat Network Ready: Detailed studies to understand the thermal behaviour of the buildings for adopting low-carbon technologies.

Organisational Readiness for Industry 4.0: Assessing readiness to adopt new technologies and identifying the best Industry 4.0 tools to ensure the estate’s resilience and adaptability.

What did we do?

The Solution

Our initiative involves the establishment of a Cyber-Physical Energy System (CPES) architecture and a smart local energy system design framework. This CPES is the first of its kind and aligns with the UK governments emergent 2023 priority – The UK’s Cyber Physical Infrastructure [ Link Reference ]. The CPES permits us to better understand, model and optimise, the integration of critical networks and services i.e. Transport + Energy + Heating. The transformative value this offers, is that we can map, explore and learn to understand this complex adaptive system of systems, and undertake disruptive research into the social-techno-economic and environmental multi-objective optimisation of decarbonisation pathways. The CPES integrates real-time monitoring, machine learning, and AI-based digital services to optimize energy consumption and streamline data management for various decarbonization efforts. Designed to be technology-agnostic, our framework ensures interoperability and coordination of multi-physics sensing and actuator assets, making it widely applicable.

We have successfully implemented this system at The Crichton Trust estate in Dumfries, UK. The CPES has empowered the estate to enhance processes through real-time data visualization, accurate forecasting, and intervention tracking, fostering a culture of innovation and evidence-based decision-making across the entire community.

The Impacts and Benefits

Impacts for the Company 

The Cyber-Physical Energy System developed through KTP project has created a real-time digital persona for the estate, enabling intelligence-led adaptation, improved operational decision support, and net-zero investment. By exploring low-cost solutions and operational adjustments, we have tackled challenges posed by heritage sandstone buildings. This has led to significant outcomes, including a 20%-28% reduction in natural gas usage in these buildings. These savings could translate to annual financial savings of £65,000-£132,000 across the entire estate.

Our framework's transferability and scalability promise future impacts at local, regional, and national levels. The abundance of sandstone buildings worldwide means our findings have immense social and commercial value. Our efforts have gained credibility, allowing The Crichton Trust to host a stakeholder meeting for Whole-System and Regional NetZero Planning. This innovative approach fills a crucial knowledge gap for achieving NetZero pathways.

Decarbonizing heat in the UK and beyond requires wider adoption of low-temperature heat. There is a significant knowledge gap regarding the capability of existing buildings to utilize low-temperature heat. Our work has already influenced plans for a district heat network at The Crichton estate, 4 NHS hospitals, local council estates, and over 600 homes, driving the community towards NetZero and contributing to economic sustainability.

Impacts for the Academic Team

Cyber Physical Energy Systems are crucial for a comprehensive energy transition. Through our KTP work, we have developed a concept of symbiotic systems engineering to explore, understand, and coordinate dynamic interactions among the community, built environment, technology, and environmental factors. With no off-the-shelf solutions for decarbonization and NetZero, our initiative fills these gaps, promoting public understanding of sustainable energy practices.

At The Crichton Trust, we have facilitated events focused on whole-system energy and regional NetZero planning for south Scotland. Collaborations with EPSRC-funded projects and guest lectures, including one at the Royal University of Bhutan, underline our engagement. Presentations to national bodies such as Zero Waste Scotland and South of Scotland Enterprise emphasize our work's significance.

Our initiative has received nominations for the Scottish Knowledge Exchange Awards 2024 and the Innovate UK Knowledge Transfer Partnership Awards, recognized by industry partners like SPEN and SGN. This recognition has enhanced collaboration with industry and community partners, broadening our impact.

Our established CPES architecture has led to partnerships with the University of Glasgow’s Communication Sensing and Imaging research group and Radisoft Sensor. We are exploring replication at the University of Glasgow’s campuses, demonstrating the broader applicability and impact of our research.
