Unlike a lot of sustainability platforms, Redaptive ONE is supported by our best-in-class Internet-of-Things (IoT) meters. Weve installed over 10,000 of our IoT meters throughout the US, Canada, and Europe since , measuring ~ 300,000 pieces of equipment. However, not all energy meters can track the same types of data or at the same scale.

Here are 4 factors to consider when choosing an energy meter:
1. Granularity
To meet your energy savings goals, youll need timely asset-level data to make decisions. Many facilities get a utility bill that reflects what the monthly energy usage was, but not when, where or why.
Look for meters that provide real time data (hourly or even minute-by-minute) and equipment/circuit-level visibility that tell the whole energy story of your building.
2. Data Verification
One of the biggest challenges in the Energy-as-a-Service industry is making sure the data is correct. This is often due to the fact that your electrical infrastructure changes over time, and your panel schedules may contain old or incorrect labeling.
Look for a meter system that (1) utilizes software and AI to analyze the data and validate mapping and data quality (2) offers human support to help analyze the data further and provide QA.
3. Security
Know where your data is stored and how its accessed. When researching meter options, look for one that transmits data outside of the in-building network (perhaps by cellular) and that offers strong encryption and segregation of data.
4. Cost Efficiency & Scalability
To get the best picture of equipment usage in a building, you will want to measure as many circuits as possible. Select a solution that captures at least 42 circuits to drive down price per point. Most meters only have around 2-18 channels; save yourself time and effort by choosing a meter, such as Redaptive ONE, that can capture real-time insights across 48 channels.

As my colleague Arvin Vohra recently wrote, Fortune companies are headed for a climate cliff in part because they dont know how to properly address their energy usage. Data is important, but it wont get you far if you dont have the right visibility. Choosing the most effective energy meter and insights platform will help your business identify cost-savings opportunities and address potential energy usage issues before they have a major impact on your business.
We go into even more depth on this issue and on our recent blog post. Redaptives solution collects data for smarter decision-making and building resilience. Reach out to learn more.
The type of din energy meter to be selected should be determined according to the type of load.
The principle of selecting a din energy meter should be based on the electric load within 20%-120% of the rated current of the din energy meter. The appropriate din energy meter should be selected based on the value of the load current and voltage, so that the rated voltage and rated current of the din energy meter are equal to or greater than the voltage and current of the load.
The rated capacity of the din energy meter should be selected according to the user's load. The upper limit of the load current should generally not exceed the rated current of the din energy meter, and the lower limit should not be lower than the load current specified within the allowable error range of the din energy meter.
1. For a din energy meter that is not equipped with a current transformer and is directly connected to the line, the actual electricity consumption for the month is calculated as: actual electricity consumption for the month (kW·h) = (this month's reading - last month's reading) × multiplier.
2. When connected through a current transformer:
When the din energy meter is used in conjunction with a current transformer, the actual electricity consumption for the month is calculated as: actual electricity consumption for the month (kW·h) = (this month's reading - last month's reading) × current transformation ratio.
When the din energy meter is marked with a multiplier, the actual electricity consumption for the month is calculated as: actual electricity consumption for the month (kW·h) = (this month's reading - last month's reading) × multiplier.
When the din energy meter is used in conjunction with voltage and current transformers, the actual electricity consumption for the month is calculated as: actual electricity consumption for the month (kW·h) = (this month's reading - last month's reading) × current transformation ratio × voltage transformation ratio.
When the din energy meter is marked with a multiplier and used in conjunction with voltage and current transformers, the actual electricity consumption for the month is calculated as: actual electricity consumption for the month (kW·h) = (this month's reading - last month's reading) × current transformation ratio × voltage transformation ratio × multiplier.
If the current ratio and voltage ratio are marked on the din energy meter, this is a set of meters. If the current transformation ratio is marked as 100A/5A and the voltage transformation ratio is V/100V, it means that the current transformer equipped with the din energy meter should be 100A/5A, and the voltage transformer should be V/100V. Therefore, the reading of the matched din energy meter is the actual electricity consumption, and there is no need to multiply the current and voltage transformation ratios.
If the transformation ratio marked on the din energy meter does not match the changes of the voltage and current transformers, the actual electricity consumption for the month is calculated as: actual electricity consumption for the month (kW·h) = (this month's reading - last month's reading) × (the multiplier of the transformer × current transformation ratio × multiplier / the marked voltage transformation ratio × current transformation ratio).
