A pilot project in two of the organisation’s managed properties

In 2020, BrainBox AI and GWL Realty Advisors launched a pilot project in two of the organisation’s managed properties located in downtown Toronto.

BrainBox AI installed its cutting-edge technology into a 300,000 sq. ft. commercial office tower, where BrainBox AI controls approximately half of the building, and a 500,000 sq. ft. multi-residential building, where common areas on various floors are controlled, to convert the existing HVAC equipment into autonomous systems using artificial intelligence, cloud computing, and a set of custom curated algorithms. After few weeks of data mapping, building analysis and an AI learning period, BrainBox AI was able to establish a strategy unique to each building by enriching the buildings’ existing data sets with external weather and tariff structure data, resulting in a significant reduction in asset and equipment run times as well as energy consumption from HVAC operations.

Achieving 25-29% energy savings in two properties

Energy savings on HVAC* equipment



Metric tons of CO2 avoided per year


This resulted in energy savings on HVAC equipment of 29% and 25% respectively after only a few months.

Annualised savings for both projects amount to over half a million kWh, which is equivalent to approximately 400 metric tons of CO2 avoided per year. Satisfied with these promising results, GWL Realty Advisors is now looking to implement BrainBox AI across more buildings within its portfolio, starting with another commercial building in the city of Toronto.

"As a leading real estate advisor, we’re focused on evolving our sustainability platform to meet the demand for smarter, climate-resilient buildings for our tenants. We’ve seen great results in our pilot projects with BrainBox AI and are evaluating other assets where we can implement this technology."
