In it, Butler gives an overview of his work experience at BRE, talks about what motivated him to become a CIBSE trainer, and discusses what he’s most looking forward to in this new role.

Asked what he would tell someone who is just about to start or considering working in the sector, he says that building services are key to making buildings healthy, comfortable and productive places to live or work, and stresses the importance of the role of building services in the context of climate change.
