The career path of a building services engineer can take a very wide range of directions. Within the broad field of building services engineering, new roles are emerging, for example specialization in renewable energy, sustainability, low-carbon technologies, energy management, building automation, and building information modeling (BIM). Building services engineers increasingly seek status as accredited LEED (Leadership in Energy and Environmental Design), BREEAM (BRE Environmental Assessment Method), or CIBSE Low Carbon Consultants (LCC) and Energy Assessors (LCEA) auditors, in addition to their status as chartered/professional engineer.
