SBUK Symposium welcomes Jonathan Davies to 2025 speaker line-up



We are delighted to welcome Jonathan Davies to the SBUK Symposium 2025.


Jonathan will present High Performance, Low Carbon: Parc y Rhodyn, telling the story of the UK’s first certified off-grid Passivhaus.



Working with Huff & Puff, this straw-insulated self-build in Carmarthenshire, a finalist in the Passivhaus Trust Awards 2023, was delivered under the Welsh One Planet Development framework. It demonstrates how bio-based and recycled materials can deliver resilience, affordable warmth and very low energy demand.


A long-standing advocate for improved building standards, Jonathan promotes the demand-based metrics of AECB CarbonLite and Passivhaus to deliver low impact, high performance homes.


Early bird and member discounts are now available.
