What is Verdigris?
Verdigris is a powerful energy management platform for commercial facilities. Our technology combines proprietary hardware, artificial intelligence, and software applications to deliver actionable insights about your building operations.
What forms of operational efficiency can you detect?
We can help you detect:
- Broken Equipment – figuring out what’s not working, why, and repairing the problem
- Unexpected Scheduling – someone on staff changes the BMS schedule incorrectly
- Undiagnosed Issues – you learn about problems in your building from occupants, not your staff
What is short cycling?
Short cycling is the rapid turning on and off of a mechanical system, and occurs frequently in air-compressors, furnaces, chillers and AC units. It can be caused by dirty air filters, an oversized system, or the differential pressure being set too small. This rapid state-change adds unnecessary stress on the system, reducing its lifespan and efficiency. In addition, it can mean that the air-conditioning running off the chiller, or the power-tools connected to the air-compressor will underperform.
What is motor current signature analysis?
Motor current signature analysis (MCSA) is a highly valuable predictive maintenance tool that we use to detect motor faults. Motor current signals are analyzed and characterized as a waveform. Electrical or mechanical faults contribute to the current signal and impacts the waveform. The current signals are analyzed for specific fault signatures that deviate from expected behavior.
What is disaggregation?
Disaggregation is the ability to detect and track individual appliance loads from the context of their aggregate circuit feeds. Our smart sensors collect thousands of data points per second. This enables us to characterize and separate device signatures, something that would otherwise require a lot of sensors to understand.
How do you automatically detect issues?
Verdigris takes hundreds of millions more data points than a utility smart meter - every hour. We use smart sensors that attach to your electrical panel wiring. This enables our artificial technology and algorithms to ’learn’ about your building.
How does Tracker work?
Tracker is a mobile app that you can configure to notify you about important electricity-based, building activities. When an event you care about happens, you will receive an alert instantly. For example Tracker can inform you of setpoint deviations, equipment operating anomalies, increasing power demand during peak periods, occupancy-based lighting, etc.
How do you detect machine health or motor faults?
Our smart sensors sample information at very high frequency and look for anomalous energy signatures. In the case of motors and other rotary equipment, we can currently detect most rotor bar failures and stator winding faults. We have a rich set of data and are continuing to work on ways to detect more common types of failures.
What is your analytics offering?
We have three products:
- Web dashboard to provide insights on your building's energy consumption.
- Tracker, a configurable mobile app, to send you alerts.
- Lobby dashboard, a visual presentation of your energy use that can be displayed on a screen in your building’s lobby.
How is Verdigris software (web and firmware) managed, and how is it done remotely?
Verdigris relies on persistent network connectivity to remotely manage and update hardware firmware. Firmware releases are tested and deployed to the full network of Verdigris hardware. The system intelligently unpacks software updates in a separate partition to preserve data collection during upgrade cycles. When the system verifies the complete update, the system boots to the new firmware partition. Updates result in roughly 3-10 seconds of downtime. The system architecture supports future upgrades where we will be able to deploy partial package upgrades to minimize downtime and increase robustness.
For software access, all our current applications are developed as web-based services, accessible via any internet connected device. Software updates are continuously delivered on an ongoing basis. Anyone accessing our systems through a browser will get the latest updates.
Restful API access is versioned and developer keys are authenticated to all versions and a notification is sent to holders of all developer keys when a new API version is released.
Where can I access the data?
Your data is stored in the cloud and can be accessed from any mobile device. The communications gateway transmits the data either through Verizon 4G/LTE or your WiFi network.
What is demand management?
Demand management means reducing the power that your building uses (demands) at certain times of the day. Demand charges can account for 30-50% of your monthly electrical bill so controlling demand can have significant economic impact. For example, while your kWh rate could be $0.10, the single highest 15 minute usage could be charged at $20.00/kW.
Based on your electricity rate structure, you may be charged for high demand during peak periods of the day.
Does this require a trained electrician?
While we pride ourselves on the simplicity and ease of our installation process, we recommend working with a trained installer especially when installing in live panels. It typically takes 30-120 minutes for an experienced electrician to install our system.
How does Verdigris integrate with my BMS to control lighting, hvac, fans, etc?
We install our highly secure computing appliance onto your existing network operating center via internet. Once configured for your BMS system, our AI will run through a calibrated discovery of your BMS system and identify potential optimizations. Our team of highly skilled solutions architects then work closely with your team or your control vendor to implement the automation strategies that mean the most for your business.
What is a demand charge?
A demand charge is the largest kW interval for the month. A typical interval would be 15 minutes. An electricity bill often includes two components: total energy consumption (based on $/kWh) and the demand charge (based on $/kW).
Does the system need any maintenance after it’s installed?
Our systems are connected to an always-on self-healing network. Firmware updates are automatic so that you don't have to worry about routine maintenance. For specific malfunctions or hardware defects, our support team is on standby to fix any issues.
Can Verdigris install on a live electrical panel?
Yes. In certain high-voltage panels without spare breakers, a special live-clamp adapter needs to be installed by a trained electrician. Always use the proper safety precautions when operating in live-voltage conditions and check your local code compliance before attempting a live install.
Where can I install the systems?
Our systems can be installed anywhere there’s a wire with power on building mains, distribution panels and branch circuits. You can capture building level data from primary distribution panel or if you’re looking to target high value or critical systems, we recommend installing on branch circuits.
What makes it smart?
Our patented sensors track energy through an always-on AI that consumes more detailed information than any other solution, and can learn your equipment over time. It tracks energy output down to the microsecond and has equipment-level data.
What does your smart sensor do?
Our smart sensors clamp onto electrical circuits to track your energy consumption and sends the data securely over Wi-Fi or Verizon 4G/LTE to the cloud.
Does it work in my country?
Our system is currently certified for use in 38 countries including the United States, European Union (32 countries), China, Malaysia, Mexico, India, Canada. While each system natively supports wifi and 4G, we currently have 4G partners in US and are expanding.
Other territories not listed here may accept our CB certificate. Please reach out to us to inquire about a specific region.
How are Verdigris hardware systems managed?
Once the manufactured devices are activated on our network, our systems behave very much like a mobile smart phones. Each device is characterized as always-on and architected to dial home. Two-hour heart beats are applied to make sure the network connection is alive. Devices can operate independently without network for up to 2 hours after that they will enter a network keep alive mode where data is backed up and network retry will continue indefinitely. Each device has unique identifiers that can be commissioned through a central system which is managed on our cloud.
Can one system track more than one panel?
In some instances, one system can monitor more than one panel - as long as the panels are next to each or less than three feet apart. You can connect up to 42 sensors to a single system which serves as the communications gateway. We may recommend installing more than one system depending on your needs and configuration such as the electrical usage patterns of the facility, the electrical equipment you wish to monitor and where electrical panels are located.
