Climate Action Series 2: Retrofitting

Dr. Carlos Calderon followed with a presentation on energy and carbon modelling in buildings and communities. He discussed the role of smart technologies in enhancing energy efficiency and the potential of integrated grid retrofitting packages to meet energy targets at both domestic and international levels. Dr. Calderon shared insights from his work on housing projects in Newcastle, demonstrating how these innovations can be practically applied. 

Dr. Carlos Calderon is a Senior Lecturer in the School of Architecture at Newcastle University. With a background in civil engineering and applied computer science, his research spans energy and carbon modelling, smart materials, and intelligent systems. He collaborates with local authorities, policymakers, and technologists to transition cities towards a clean and affordable energy future. 

Dr. Bartolomeo Pantò concluded the presentations by discussing the impact of climate change on building structures. He highlighted the need for sustainable seismic retrofitting techniques to address the vulnerabilities of older buildings. Dr. Pantò showcased innovative materials, such as sisal-based bricks, that enhance structural resilience against climate-induced stresses like groundwater fluctuations. 

Dr. Bartolomeo Pantò is an Assistant Professor in Structural Engineering at Durham University. His research focuses on ensuring the sustainability and resilience of the built environment, with a strong emphasis on historical structures and climate change. Dr. Pantò has led significant projects, including developing new environmentally sustainable retrofitting techniques for masonry structures. 

During the Q&A session, the speakers underscored that many retrofitting technologies are ready for adoption. They stressed the need for consistent political will, long-term financing, and comprehensive support to encourage widespread uptake. The experts proposed creating one-stop shops where councils can offer advice, support, and access to retrofitting packages. They emphasised that retrofitting is a practical solution that individuals can control, making it an essential component of the energy transition. 

Other key questions addressed included: 

• What are the main reasons for the low levels of deployment of energy efficiency and low carbon technology retrofits in residential properties across the city? 
• How do we encourage the use of smart technologies in residential properties across the city? 

• How can we best encourage the uptake of retrofitting measures through advice and support? 
• What funding is available to support communities on retrofitting? 
• What are the latest developments in retrofitting that can be employed at the local level? 

This seminar provided a comprehensive overview of retrofitting as a viable pathway to sustainability. It highlighted the importance of strategic alignment across sectors and a deep understanding of human behaviour in promoting sustainable practices. By continuing this dialogue and fostering community engagement, we can make significant strides towards a greener, more resilient urban future. 

As we reflect on the insights shared, it’s evident that achieving sustainability requires a collective effort. The Climate Action Series has provides a venue to discuss the evidences present in the university, challenging us to critically consider our role in the ecosystem and how we can contribute to a sustainable future. Through ongoing research and collaboration, we can make meaningful progress in retrofitting our environments for the better.
