The new Elementary Teachers' Federation of Ontario office building is located in a historic residential neighbourhood. The building is four-storeys and also includes one level of underground parking.

The ETFO headquarters is conceived as a pinnacle of sustainable building practice with a minimum 60% energy reduction over the Model National Energy Code Building (MNECB), achieving LEED Platinum Certification. The ambition is to be the greenest, and most energy efficient commercial office building in Metro Toronto.

S + A Services Included:


The ETFO building is serviced by a customer owned, high voltage substation containing a 1000kVA high voltage transformer located in the basement parking level. A 150kW natural gas generator, located in an outdoor sound-attenuated enclosure on the roof of the building, provides the emergency power for the life safety and non-life safety systems. The building's lighting system uses a lighting control system with wireless control devices to maximize energy efficiency through the use of occupancy sensors and daylight sensors throughout the building. All lighting located near windows were specified to be dimmable to provide occupant comfort while maximizing energy efficiency. The building's fire alarm system was also a fully addressable, single stage system and used to control an active smoke control system for the interconnected floor space in the main atrium.


The telecommunications design consisted of Category 6 horizontal cabling infrastructure, with complimentary single mode and multimode backbone cabling infrastructure. A server room was also part of the design, housing the client's critical information servers that are accessed regularly by teachers all across Ontario. This facility was the first deployment of Voice over Internet Protocol (VoIP) technology for ETFO. The facility also incorporated an IP enabled audio/visual system that was integrated into the network infrastructure design.


Security services included design of and integrated Internet Protocol (IP) video surveillance (CCTV) system as well as electronic card access control and intrusion detection system throughout the facility.
The intrusion detection system was integrated with the Building Automation System (BAS) to facilitate automated opening and closing of windows during days when weather conditions are favorable.
An audiovisual duress alarm system was also designed to provide building occupants with ability to request urgent assistance with the parking levels. The CCTV system was integrated with the duress alarm system to facilitate automated surveillance of activated duress stations.
