Shoppers Drug Mart recruited AirTest to increase the efficiency of the HVAC systems at many of their existing locations.

1140 locations were retrofitted with 4-5 sensors per store (1 per RTU).

The energy payback period was under 2 years, and the installation at all locations was funded in part by rebates from gas and electricity providers.

Initial findings showed a savings of 18% on energy consumption.
