The 9th annual CIBSE Technical Symposium, “Transforming Built Environments - driving change with engineering” took place at the University of Sheffield from 25-26 April 2019.


The 2019 symposium provided an opportunity to examine and share research, development and applications that will drive change in the regulation, creation and maintenance of the built environment as well as evidence where there are still clear opportunities to benefit from established practices.
