BrainBox AI installed its leading-edge technology into a 509,612 sq. ft. shopping centre in Granby, Quebec, where approximately 60% of the building was controlled, to convert the existing HVAC system into an autonomous one using artificial intelligence, cloud computing, and a set of custom curated algorithms. After a few weeks of data mapping, building analysis and an AI learning period, BrainBox AI was able to establish a strategy unique to the building by enriching its existing data sets with external weather and tariff structure data, resulting in an impressive reduction in asset and equipment runtimes as well as energy consumption from HVAC operations.
Having a small building management team, BrainBox AI engineers and project managers also offered significant value by delivering ongoing client support and acting as an extension of the client’s team.

This resulted in electricity savings on HVAC equipment of 205,214 kWh (21%) after a year of operation with BrainBox AI. Total monetary savings for the year amounted to 19,249 CAD, significantly reducing the shopping center's operating expenses and improving its net operating income.
Aligned with the clients primary goals, BrainBox AI’s technology helped improve operational efficiency by optimizing the usage of certain HVAC equipment autonomously, the result of which was an average reduction in equipment runtime of 55% (see table for breakdown per piece of equipment). BrainBox AI was able to achieve these savings and reduction in equipment runtime while avoiding any fluctuations in average zone temperature* (average temperature of 69 °F with BrainBox AI, versus 68.9°F without BrainBox AI.)
The success story of this shopping center is a prime example that building efficiency can be easily and quickly achieved with smart HVAC technology. At BrainBox AI, we are proud to have helped the client in realizing these great results.
