Case Study: Global Insurance Provider achieves 50% energy savings with Building Engines Hank

Hank drives savings and reduces energy consumption by 50%

A Global Insurance Provider was struggling with a Class A office building that had a unique HVAC configuration, pressure-control problems, and energy waste from systems running 24/7. Building Engines, through its Hank service, was brought in to help the ownership team reduce the portfolio’s carbon footprint and address these operational and security challenges.

Building Engines and Hank worked with onsite technicians to correct a misinstalled pressure sensor, then applied AI-driven control logic, optimal start/stop scheduling, and regression-based optimization for supply air temperature and fan control. The result was an average reduction of 70,000 kWh per month, nearly 50% lower energy use, and more than $3,500 in monthly cost savings, while also achieving 50% total energy savings.
