Case Study: Large Research Laboratory achieves $286,000 in annual energy savings with Clockworks Analytics

Clockworks™ building analytics implemented in large research laboratory enables energy cost savings and utility program incentives

Large Research Laboratory, a 450,000 sq. ft. research facility in Cambridge, MA, struggled with widespread HVAC issues across its central and zone ventilation systems — hundreds of VAV boxes, leaking and malfunctioning coil valves, and instances of simultaneous heating and cooling that drove up energy use and maintenance needs. To address this, the lab implemented Clockworks Analytics’ Clockworks building analytics for automated, always-on diagnostics and prioritization.

Clockworks Analytics pinpointed high-impact faults and helped the facility schedule targeted repairs, including re-commissioning 84 VAV boxes, replacing 52 VAV reheat valves and 12 actuators, and making multiple control adjustments. Those actions delivered $286,000 in validated annual energy savings and $50,000 in utility incentives, with notable savings broken out (e.g., $137,000 from a leaking preheat valve, $61,400 from a leaking cooling valve, and $87,600 from reduced VAV reheat load), demonstrating Clockworks Analytics’ measurable ROI and continuous fault detection.
