What is the Open Energy Efficiency Meter?

The OpenEEmeter creates a standard weights and measures for energy efficiency that is reliable for both markets and grid operators. In simple terms, this means that using the meter, private companies, utilities, and regulators will all calculate the same level of savings for a given set of building efficiency projects.

By providing near real-time access to metered gross savings, realization rates, and other performance metrics, the OpenEEmeter creates a virtuous cycle in which good results are reported and rewarded.

Real-time measurement and verification of actual savings will enable both regulated utilities and private markets to invest in energy efficiency as a reliable, cost-effective resource with consistent and reliable returns.

Because it is open source, you can see how it works, so you can trust it, and anyone can use it for free.

The OpenEEmeter is an open source public tool that provides performance feedback based on a standardized, data-driven approach. The OpenEEmeter platform is built on existing open industry tools including HP-XML, Green Button, and the DOE Building Energy Data Exchange Specification (BEDES). All source code is Open Source and available for scrutiny and contribution for stakeholders.

The OpenEEmeter is based on an open standard calculation that is both transparent and replaceable and represents the equivalent of a standard weights and measures for energy savings.

The Open Energy Efficiency Meter calculates savings where it matters, at the meter.
