Role Models


As part of our work to drive diversity and inclusivity within the built environment sector, we recognise that it is important to shine a light on positive role models from underrepresented groups of people within our industry. We're working to ask a diverse range of individuals from across the CIBSE community to share their stories and experiences to help inspire our future workforce.
