Energy Savings

Manufacturers, utilities and facilities management are all seeking ways to comfortably lower power usage in order to save money and reduce environmental impacts. The Tignis solution detects issues that decrease efficiency—including mechanical, control and situational changes.

Expanded Detection Capabilities Saves Energy

  • Detecting efficiency losses immediately: Tignis builds models that predict how much energy usage an individual asset—as well as the aggregate system—should be expected to consume. Tignis can detect when more energy is being used than expected, at the earliest possible moment.
  • Deviation from normal: The type of detection includes, for example, identifying manual values that are open/closed when they should not be, automatic valves that are stuck or leaking, and cases where automated controls are being overridden, leading to suboptimal conditions.
  • Underperforming assets: Since Tignis understands system-wide structures, when there are multiple comparable assets, their asset power utilization at given loads can be compared—thus identifying assets with less than optimal efficiency.

 

Tignis Delivers Real Value, Every Day

Heating, ventilation and air conditioning (HVAC) is responsible for a significant portion of power consumption, so this is where Tignis focused its initial energy savings efforts. Optimum Energy uses Tignis software to detect faults in vast amounts of chiller plant sensor data. Tignis helps Optimum Energy achieve the following efficiencies.

  • Automate condition monitoring of hundreds of chiller plants worldwide, solving the “snowflake” issue of sensors configured differently at each location.
  • Provide reliable fault detection with analytical models covering situations too labor-intensive to monitor.
  • Reduce false positives by monitoring and assessing a vast amount of anonymized data, resulting in a curated list of meaningful faults that can be acted upon.
