Case Study: GWL Realty Advisors Inc achieves up to 29% HVAC energy reduction and 500,000+ kWh/yr savings with BrainBox AI

Gwl Realty Advisors Enabling Greener Buildings In Downtown Toronto

GWL Realty Advisors Inc, a leading North American real estate investment advisor, aimed to reduce the energy and carbon footprint of its downtown Toronto assets. In 2020 the company piloted BrainBox AI’s technology in two properties — a 300,000 sq. ft. commercial office tower (BrainBox AI controlling roughly half the building) and a 500,000 sq. ft. multi‑residential building (common areas on multiple floors) — to address HVAC energy use and support a transition to more sustainable, climate‑resilient buildings.

BrainBox AI installed an AI‑driven autonomous HVAC control solution, performed data mapping and learning, and enriched building data with weather and tariff information to tune each asset. The vendor’s system reduced HVAC energy use by 29% and 25% in the two buildings, with estimated annual savings of 309,000 kWh and 254,875 kWh respectively (totaling over 500,000 kWh and roughly 400 metric tons of CO2 avoided), prompting GWL Realty Advisors Inc to plan broader deployment across its portfolio.
