London, 28 April 2025 – The CIBSE IBPSA-England Technical Symposium 2025 concluded successfully in London on 24th and 25th April. The event, which brought together industry leaders, researchers, and professionals from around the world, focused on cutting-edge advancements in sustainable building design and performance.
Organized by a collaboration between CIBSE (Chartered Institution of Building Services Engineers) and IBPSA-England (International Building Performance Simulation Association), the symposium merged two of the industry’s leading events: CIBSE’s annual Technical Symposium and IBPSA-England’s biennial Building Simulation and Optimisation event. With the theme of “Fit for 2050 – Achieving Net-Zero through Intelligent, Resilient, and Sustainable Design in the Built Environment”, the symposium provided a critical platform for showcasing research, innovation, and best practices in achieving a net-zero future for the built environment.
The comprehensive 2-day programme featured 34 sessions and nearly 100 expert speakers. Keynote addresses were delivered by CIBSE’s President, Fiona Cousins, and IBPSA-England Chair, Neveen Hamza, setting the stage for dynamic discussions on the future of building performance and sustainability.
The symposium covered a diverse range of topics aimed at transforming the industry and equipping the sector to meet the challenges of decarbonization and climate resilience. Attendees were immersed in technical reviews, case studies, poster presentations, and thought-provoking discussions.
Key topics included net-zero carbon methodology and benchmarks for commercial buildings, decentralized ventilation for carbon reduction in UK offices, decarbonization strategies for stadium buildings and homes, the role of passive design and smart technologies in achieving sustainability, building resilience against climate change through effective design strategies, and innovative approaches to district heating systems and energy-efficient retrofits.
Fiona Cousins, CIBSE President, stated, “The CIBSE IBPSA-England Technical Symposium 2025 was a vital forum for exchanging ideas and fostering partnerships, equipping our sector with the tools needed to model and measure building performance for the future. This partnership encompasses well-established and urgent work in support of decarbonization, as well as emerging research and innovations focused on occupant health and well-being – an area rapidly evolving due to advances in sensor technology and AI-driven analytical methods.”
Neveen Hamza, IBPSA-England Chair, added, “The collaboration between IBPSA-England and CIBSE to organize and host this conference reflects the challenges and opportunities we face, as both an academic and professional community, in our efforts to be fit for achieving net-zero in a built environment where more than 80% of the building stock that will exist in 2050 is already in place. This conference showcases the latest cutting-edge research and technologies to help realize our ambitions for a more sustainable and climate-resilient built environment.”
The symposium not only advanced the conversation around sustainable building design but also paved the way for ongoing collaboration within the sector. As the industry continues to tackle the challenges of decarbonization and resilience, the momentum from this event will undoubtedly influence the future of building performance for years to come.
