This project is piloted by the firm SPI from Toronto, fluorescent ballasts were replaced by new dimming ballasts controlled by 0-10 Vdc analog input. It is thereof possible to control the intensity of fluorescent fixtures to fit the required level resulting in a reduction of energy consumption.

Relays using PLC technology (Power Line Communications) which uses the same pair of wires that bring electricity to the device for conveying control signals were used, significantly reducing installation time system.

Light sensors were installed in the periphery and constantly measure the contribution of natural light from windows to subsequently communicate to all relays the intensity required to get the desired lighting level. These sensors also use PLC technology and communicate directly with the relay without requiring central control system.

This approach is commonly called Daylight harvesting. (follow this link to Wikipedia's definition)

This project is still ongoing and is done in stages, gradually and as the customer completes the upgrade of floors of the building.
