How to Use the OpenEEmeter on Your Desktop (No Python Required)

This webinar is for M&V professionals, aggregators, regulators, and program managers interested in being able to calculate weather normalized metered energy consumption and corresponding savings for individual projects or portfolios. While there is an assumption of mastery of the basic principles of M&V, participants do not need to be able to program to interact with this self-contained version of the OpenEEmeter.

This webinar will give you all the tools you need to use the OpenEEmeter to calculate normalized metered energy consumption (NMEC). The Open-Source OpenEEmeter runs the CalTRACK NMEC calculation methodology, and can now run locally on your desktop -- no need for servers, python, or databases.  

In this Webinar, you will learn:  

  • What the OpenEEmeter is and how it works;
  • Why the CalTRACK methods are important for standardizing energy efficiency calculations;
  • How you can deploy your own version of the OpenEEmeter by downloading the OpenEE CLI tool and calculating normalized metered energy savings for sets of efficiency projects.

Technical knowledge required: Comfort using your computer’s Terminal functionality; familiarity with pre/post weather-normalized energy savings calculation methods.

Tuesday, September 19th, 12 pm EST/9 am PST. Register here.


Earlier this year, PG&E launched a residential Pay-for-Performance (P4P) pilot program that lays the groundwork for an entirely new approach to energy efficiency.

To make this new approach possible, PG&E and a working group of energy experts (including our company, OpenEE) agreed on a set of open methods to calculate payable energy savings. The first version of this set of methods was released this summer under the name CalTRACK.

Alongside CalTRACK, OpenEE is releasing a downloadable version of the OpenEEmeter, the open source library that includes a reference implementation of CalTRACK methods.

With this version of the OpenEEmeter, any analyst who has access to basic energy consumption data will be able to plug in numbers and get a quick and simple output of site-level energy savings. This tool is supported by extensive documentation that breaks down the mysteries of how to perform site-based weather normalized savings calculations.

In our next webinar, Tom Plagge, senior data scientist at OpenEE, will demonstrate how to use the OpenEEmeter CLI tool and will provide a primer on calculating weather normalized metered energy savings. We invite all experts in M&V to join us in exploring how consistent, transparent methods can lead to new innovations in energy efficiency programs.
