Types of IPv6 Addresses

Unlike the 32-bit addresses of IPv4, IPv6 addresses are 128-bits. These longer addresses are partitioned into 16-bit bocks; then, each of these smaller blocks is turned into a 4-digit Hexadecimal number. Built into IPv6 addresses is notation identifying the application it will be used for. The first 64-bits of the address are for routing and the last 64-bits represent the interface or node.

What is ASHRAE 90.1?

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.

What is IPv6?

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.

How Power Meters Work

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.

What are Revenue Grade Power Meters?

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.

What are Power Meters?

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.

Getting Granular with Power Metering

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:

How to Budget for Energy Management

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.
