Case Study: GPR Ventures achieves 30% energy savings and vastly improved tenant comfort with Building Engines' Hank

Hank maximizes tenant comfort throughout office campus with no capital investment

Hank, a JLL company, was engaged by GPR Ventures to address persistent comfort complaints at Metro Center, a 258,806 sq ft Class-A office campus. Despite a relatively new BMS and well-maintained hardware, tenants logged more than 80 temperature-related complaints per week; the BMS contractor recommended a >$400,000 HVAC controls replacement, but the root cause was software — and the owner wanted a fix with no capital investment.

Hank was installed, analyzed operations for two weeks, and within two more weeks took full control, using AI to reconfigure air handlers and VAV reheat units to maintain tenant setpoints within one degree and eliminate unnecessary reheating. The result: resolved comfort issues, a 30% drop in energy use, 50% fewer HVAC service calls, faster remote resolutions (within 15 minutes), roughly $400/day saved from eliminated reheating, and a 400% ROI — dramatically improving tenant experience with no new capital outlay.
