OpenEE opens the door.

Deploying open source metering to change the world of energy efficiency.

OpenEE is an enterprise software company that has taken the lead on developing the OpenEEmeter. We help utilities, aggregators and programs deploy the OpenEEmeter.

Our guiding principles

No more black-box algorithms.

Openness is so important to us that we carry it in our name. Our goal is to create a generally accepted standard for energy efficiency—one that anyone can see, discuss, validate, modify or poke holes in. It’s time for all of us in the energy efficiency community to get on the same page. The OpenEEmeter core stack is protected by the MIT License, an open source mainstay that allows software to be copied and modified without restriction, as long as the open copyright is maintained.

Multiple third parties have cross-examined our code and methods. Their analyses are available along with the source code link for anyone to closely inspect against public datasets.
Our enterprise products and consulting services help companies seamlessly deploy the OpenEE meter and visualize savings results. Find out more about OpenEE products.
To create consensus, a standard for energy efficiency must be entirely replicable. This means that any two parties using it should always get the same result. This stability allows the standard to be used as the basis of markets, creating predictable cash flows and enticing new investment into the industry.

Traditional efficiency measurement and verification (M&V) was never designed with markets in mind. By adding control groups and ex post facto adjustments to its calculations, M&V makes replicability difficult and creates uncertainty.

The OpenEEmeter solves this problem by rigorously factoring out the replicable, market-ready component of traditional M&V, while maintaining a foundation upon which supplemental M&V methodology can be built.
OpenEE can work with your company to deploy and customize the OpenEEmeter for specialized use-cases. Because the core stack is open source, you can be sure that your results will be consistent and replicable by third parties.
Built with scalability in mind, the OpenEEmeter is battle-hardened and ready to take on on massive amounts of data. Our methodology has been carefully developed to use statistical methods that allow for linear scaling. And because the OpenEEmeter requires only simple inputs--just project date and consumption figures—there’s no need to clean messy program data in order to get valuable results for any efficiency team.
OpenEE’s enterprise products build on the open source base to make data loading seamless and our Periscope dashboard provides customized, client-specific outputs for different users, from high-level overviews for team leaders to more in-depth analytical tools for data specialists.

Matt Golden

Chief Executive Officer

Whether testifying before Congress or auditing Ellen DeGeneres' house, Matt Golden has been spreading the word about energy efficiency for years.

An entrepreneur, policy advocate, and efficiency agitator, Matt is committed to bringing energy efficiency in the built environment to scale as a demand side resource. He has made presentations on emerging efficiency markets to the US Senate Finance Committee, at COP 21, and to the UK Parliament among many others.

Matt is CEO of Open Energy Efficiency, the company that developed the OpenEEmeter, an open source platform for measuring energy savings and load shape based on smart meter data. Open Energy Efficiency works with a variety of utilities, government agencies, and private efficiency providers to track savings and load shape using AMI data and enable pay for performance markets for demand side capacity.

Matt also leads the GBCI Investor Confidence Project implementing a system to certify commercial and multifamily Investor Ready Energy Efficiency™ projects in order to reduce transaction costs, and develop actuarial data to unlock capital markets for commercial and multifamily retrofit projects.

Previously, Matt founded Recurve, which developed tablet based energy auditing software for the residential energy efficiency industry based on real world experience gained through thousands of energy efficiency audits and retrofits as a licensed CA energy efficiency contractor.
