OpenEE turns energy efficiency and electrification into grid resources. 

Open source, secure and transparent, so you can have confidence in the results.

Efficiency is a Resource

Problem:  Efficiency and electrification don't meet the needs of emerging distributed energy markets.

Solution: Measure time and locational impacts, support pay-for-performance, and finance efficiency the way we finance grid infrastructure.

Let Data Drive

Problem: Efficiency and electrification are too expensive, complicated and slow to improve, with little feedback or transparency.

Solution: Rapid feedback, data-driven quality assurance, targeted optimization, and alignment of incentives.

Open Enterprise

Problem: Black-box methods and PDF evaluation reports years after the fact create lack of confidence.

Solution: 100% open source, with the modular architecture you need to support innovation and enterprise scalability.

OpenEE's time- and location-based resource curves provide unprecedented power to manage efficiency and electrification projects while helping markets pave the way toward a clean and stable distributed energy grid.

Our Mission

OpenEE's mission is to transform efficiency and electrification into time and locational distributed energy resources. 

Regulate markets, not businesses

The utility of the future doesn’t have time to micromanage efficiency programs

The current model for energy efficiency is broken. It’s time to do something different. For too long, efficiency programs have been locked into costly, top-down approaches that take years to validate and provide ambiguous results.

Energy efficiency in its current form faces an existential problem. After forty years, investment in efficiency is still just a fraction of what it needs to be to meet our climate and energy goals. At the same time, given their costs, if current efficiency programs were truly to scale up, they would go bankrupt. Typically 30-50 percent of energy efficiency budgets are allocated to administrative costs instead of projects.

There is another way: open metering and real time pay-for-performance can unlock innovation by regulating markets, not businesses. With an agreed-upon system of weights and measures for efficiency, utilities and aggregators can procure energy savings just as they would bid for any other DER.

It’s time to stop forcing utilities and regulators to pick winners and let them do what they do best: enabling markets and protecting consumers.

No more black boxes

Let’s find out what actually works, what doesn’t, and why.

Proprietary, engineering-model black box approaches to EM&V focus on deemed savings models and measure attribution, requiring complex, ex post facto adjustments to account for variable results.

As a result, actual information on which efficiency providers are getting real, verifiable results is hard to come by.

By calculating efficiency on an open platform using only energy consumption and weather data as inputs, we can provide insights that were never before available. And the results are open, third-party verifiable and reproducible.

Grid 2.0 is coming

Will energy efficiency be able to meet the challenge?

In a world of smart energy grids and distributed, renewable resources, a system that measures efficiency based on monthly metering and calculates results years after the fact simply won’t cut it. To take its place as a true DER and meet the needs of Grid 2.0, efficiency will have to deliver savings at the times and places where it really matters.

Unleash the pent-up innovation of the efficiency industry

Innovators are ready to transform the efficiency industry. We just need to give them a platform to do it.

From smart thermostat makers to demand-response app developers to home zero-down home performance financiers, businesses are coming up with more and more innovative ways to drive efficiency investments and deliver energy savings.

What these companies need is a more streamlined access to markets that can value the benefit they’re creating along with the new revenue streams and larger demand that comes from a pay-for-performance, procurement-centered market.

With access to open measurement tools, these companies will be able to use data to make deploying and managing their businesses more efficient.

And by focusing on procuring measurable, verifiable savings at the meter and paying for actual performance, utilities and program managers can stop worrying about what measures will work, and allow the market to come up with efficiency innovations that none of us have even thought of yet.

The OpenEEmeter makes it possible

What is the OpenEEmeter?

The OpenEEmeter is an open source software platform for calculating energy efficiency. Using the meter, private companies, utilities, and regulators can all calculate the same level of savings for a given set of building efficiency projects.

The meter’s core stack is 100% open source licensed, meaning that anyone can download the code, inspect it and modify it.

Being open source makes third-party verification of methods easy, which in turn helps to validate results and ensure that all parties are working under the same set of assumptions. It also prevents vendor lock-in.

At the same time, anyone is free to build proprietary tools on top of the code.

Focus on deemed savings models and measure attribution requires complex, ex post facto adjustments to account for variable results.
Focus on normalized metered savings at the site level allows for a radically simplified and scalable approach.
Different proprietary models get different results depending on what factors are considered.
Uses only energy consumption and weather data as inputs; process and results are open, third-party verifiable and reproducible.
Time consuming - results often come years after the fact.
Outputs updated in real time as fresh data is received.
Typically 30-50% of energy efficiency budgets are allocated to administrative costs instead of projects.
The OpenEEmeter can be downloaded and used for free to calculate energy savings.
Long feedback loops require top-down micromanagement of projects by programs.
Quick feedback of reliable results reduces uncertainty and sets the stage for pay-for-performance programs.
Focus on monthly averages limits measurement to overall savings.
Using building smart-meter data, the OpenEEmeter can calculate the hourly impact of efficiency measures on load-shape, allowing utilities to procure greater savings at different times of the day.

The OpenEEmeter is the open source measurement tool the industry needs.
