Last year's CIBSE Technical Symposium took place from 11-12 April at the Welsh School of Architecture, Cardiff University. 

The focus of the 2024 CIBSE Technical Symposium was on defining and delivering building performance so that buildings, new and existing, are fit for the future, in the context of the digital revolution, increased climate change impacts, a new focus on health and wellbeing, and the renewed imperative for building safety.
