The Challenge
GPM had a global objective of reducing greenhouse gas emissions and energy consumption by 20% from 2012 levels, by 2020.
To this end, GPM was interested in implementing energy conservation measures and technologies, which help achieve these goals while improving the overall reliability of their operations.
Results achieved
• Energy savings financial summary
• Energy savings: $152,173 (annual)
• Simple payback: 0.19 years
• Net present value: $177,856
• Other operational benefits
• Improved sustainability and environmental stewardship. Achieved 800+ tons in annual CO2 emissions reduction, which is the equivalent of taking 170 cars off the road
• Increased staff and contractor productivity. Quantification of savings for each opportunity allowed for prioritization of workload. Root cause analysis provided by Analytika allowed maintenance staff and contract automation personnel to target their efforts and work more efficiently. Productivity as measured by savings achieved per hour improved by over 30%.
• Improved central plant load capacity by more than 10%. Reduction in building side energy consumption allowed central plant capacity to be utilized elsewhere..
Cimetrics’ Solution
Cimetrics was selected to provide its Analytika Pro solution for a 100,000 square foot, laboratory and office building, which is part of a one million square foot manufacturing, R&D and office campus. Cimetrics collaborated with GPM and their building automation system providers, Johnson Controls and Schneider Electric, to connect to and collect sensor and actuator data from almost 5,000 physical points. Data was collected every 15 minutes, 24 hours a day, 365 days a year – averaging approximately 480,000 data samples per day. The following systems were monitored: 3 Air Handling Units, 2 Hot Water Pumps, 2 Chilled Water Pumps, 10 Fan Coil Units, 29 Fume Hoods, over 400 Terminal Units, and other miscellaneous equipment.
Over 1,000 Fault Detection and Diagnostic algorithms then analyzed the data to identify opportunities to reduce energy, improve environmental conditions and reduce maintenance, operations and regulatory costs. Analytika also uncovered potential equipment problems and identified opportunities for operational uptime improvements and profitable retrofit projects.
Experienced Cimetrics engineers leveraged Analytika software to identify opportunities, determine root cause, and calculate annual savings impact for each identified opportunity. Actionable recommendations were documented and provided to the client both online through the Analytika web based portal and offline through periodic reports. Cimetrics’ role didn’t end at recommendations. Cimetrics engineers met with the client team on a regular basis to help answer technical questions, coordinate implementation, and provide regular feedback on progress.
