Case Study: Grubb Properties achieves around 20% energy savings and improved tenant comfort with PointGuard

How PointGuard deployed analytics to help reduce energy consumption and spend and proactively address maintenance and comfort issues in a Charlotte property

Grubb Properties engaged PointGuard to address inefficient operation at 1523 Elizabeth, a 39,000 sq ft office building in Charlotte. Although the building had “smart” equipment, it operated passively without fault detection or optimization, relied on reactive comfort fixes, and lacked real‑time energy visibility; PointGuard deployed its cloud‑based data analytics suite (PointGuard Intelligent Building Analytics) to tackle these issues.

PointGuard integrated the existing gateway into its analytics platform, repaired or replaced faulty sensors, installed an interval electric meter, deployed active reset algorithms, tuned economizer controls, and fixed stuck terminal dampers. The result was immediate and sustained energy savings, improved tenant comfort and extended asset life — winter electric bills dropped and long‑term energy savings held around 20% thanks to PointGuard’s solution.
