Building Environmental Systems - BES™ Program

Building Environmental Systems - BES™ - Setting the standard for certification of building operators and managers in Canada for over 40 years.

Building Environmental Systems - BES™ is the most highly recognized certification for building operators in Canada. There are two levels of certification: BES™ Operator Class II and BES™ Operator Class I. These programs train technicians in the operation and maintenance of today’s complex buildings.

The BES™ Operator Class I certificate is recognized by the Building Owners and Managers Institute (BOMI) of Canada. Upon successful completion of BES™ Operator Class I, you can apply for the BOMI System Maintenance Technician (SMT®) designation. BES™ Operator Class I graduates can also apply to be registered provincially in the Energy Training Ontario registry as well as with the Interprovincial Facility Training Accreditation Council (IFTAC).

The BES™ Facility Manager Certificate program was subsequently created to support building operators in their career paths towards management as well as a certification for entry-level managers or current managers of building systems and operations staff.

Seneca’s BES™ programs adhere to the fundamental premise that the building is a holistic system in which heating, air conditioning, refrigeration, ventilation, electrical power, lighting, water and air supply are connected and interdependent.

They focus on the knowledge required to understand the functioning of all systems in commercial, institutional and residential buildings with a strong emphasis on sustainability and energy efficiency. The programs also cover how buildings can be operated and maintained more efficiently.
