Case Study: Financial Services Company achieves 12% energy savings and restores ENERGY STAR score with PointGuard

Financial Services Company - Customer Case Study

Financial Services Company, a single-tenant 104,000 sq. ft. office in South Carolina with four 65-ton York rooftop units, was experiencing building performance drift—its ENERGY STAR score slipped from the 90s into the 80s. PointGuard was engaged, using its PointGuard/SkySpark (Cloud-Hosted) MBCx platform and managed service, to investigate widespread issues including all RTUs running 24/7, BACnet/MSTP network faults, a fan VFD left in hand mode, conflicting zone setpoints causing simultaneous heating and cooling, failed supply-air control points, overcooling, off-hours reheat, and occupant comfort complaints.

PointGuard implemented continuous diagnostics, prioritized algorithm-driven findings, and supported targeted fixes (stopping 24/7 runtime, correcting VFD and network faults, resolving setpoint conflicts and control point failures). The results included first-year energy savings of $31,580 (12%, $0.30/sq.ft.), recommissioning in four months, a simple payback under six months, an immediate 18% energy reduction in one month, and recovery of the ENERGY STAR score back into the 90s—with improved comfort and asset health observed after PointGuard’s intervention.
