ASHRAE 90.1 is a standard for measuring energy in commercial buildings. It covers many aspects of energy management, such as total consumption, HVAC and lighting systems, and individual circuits. For buildings over 10,000 square feet, with or without tenants, it is more cost effective to have multi-load, branch circuit, and high-density monitoring equipment. In buildings with tenants, both individual and total building usage need to be monitored every 15 minutes at a minimum and be recorded hourly, daily, monthly, and annually.

IPv6 is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers. First developed by the Internet Engineering Task Force in the 1990s, IPv6 became a full standard in 2017. However, its spread and usage in the world has not been as fast as anticipated. In 2012, IPv6 was permanently enabled by Internet Service Providers, networking equipment manufacturers, and web companies.

Power meters are used in a wide variety of applications to measure electricity use on a more granular level than the main utility meter. Power meters, or submeters as they can sometimes be referred to as, can tell you where, how, and how much electricity is being used in the building.

Revenue grade power meters are defined in the American National Standards Institute (ANSI) standard C12.20-2010 Class 0.2. The intention of such a standard is to establish the requirements for power meters so the meters in question accurately and reliably provide monitoring. This ANSI standard has 3 accuracy classes: 0.1, 0.2, and 0.5. These classes correspond to accuracy at full load and include CTs.

Power meters measure utilities like electric, gas, or water to increase building performance. With a power meter, users can get granular data on the use of energy of a building. Such granularity can reveal any equipment or systems adding to energy waste. Submeters can be used in any type of building, from manufacturing to apartments. Meters make it easy to visualize and optimize energy usage.

Before delving into the importance of granular data for power metering, it is essential to understand why a submeter is used. Submetering provides the ability to monitor the actual energy usage of individual tenants, departments, or pieces of equipment in real time. It allows for measuring electricity on a more granular level than the building's main utility meter. With submetering, the user can determine system efficiency and identify equipment problems, thereby better understanding trends and energy usage. This is useful for:

Companies today don't invest in energy management for a myriad of reasons. Many view energy management as an expense rather than an investment. Energy costs often account for the largest portion of a company's expenditures, but there way be several barriers to overcome before investing in energy management.
January 09, 2020
Choosing the right power meter involves considering many factors. Whether it is for tenant submetering, submetering a commercial building, power monitoring for energy management, or another application, a power meter should meet certain specifications. Although each individual application will have its own requirements, there are several common factors to evaluate. When exploring options for a power meter, it is important to know the:

Many costs are associated with implementing an energy management strategy for a company, including hardware, software, and labor. Choosing the right power meter to fulfill the needs of said strategy is critical for the success of any project. Delivering on the ROI of the strategy is key to meeting the objectives of the energy management strategy, so be sure to keep in mind the initial cost for a faster ROI.
