EEmeter — an open source python library for creating standardized models for predicting energy usage. These models are often used to calculate energy savings post demand side intervention (such as energy efficiency projects or demand response events).
OpenEEmeter, as implemented in the eemeter package and sibling
eeweather package <http://eeweather.openee.io>_ builds upon the foundation of the
CalTRACK Methods <https://caltrack.org/>_ to provide free, open-source modeling tools
to anyone seeking to model energy building usage. Eemeter models have been developed to
meet or exceed the predictive capability of the CalTRACK models. These models adhere to
a statistical approach, as opposed to an engineering approach, so that these models
can be efficiently run on millions of meters at a time, while still providing
accurate predictions.
Using default settings in eemeter will provide accurate and stable model predictions suitable for savings measurements from demand side interventions. Settings can be modified for research and development purposes, although the outputs of such models may no longer be an officially recognized measurement as these models have been verified by the OpenEEmeter Working Group.
.. note::
Please keep in mind that use of the OpenEEmeter is neither necessary nor
sufficient for compliance with the CalTRACK method specification. For example,
while the CalTRACK methods set specific hard limits for the purpose of
standardization and consistency, the EEmeter library can be configured to edit
or entirely ignore those limits. This is becuase the emeter package is used not
only for compliance with, but also for *development of* the CalTRACK methods.
Please also keep in mind that the EEmeter assumes that certain data cleaning
tasks specified in the CalTRACK methods have occurred prior to usage with the
eemeter. The package proactively exposes warnings to point out issues of this
nature where possible.
EEmeter is a python package and can be installed with pip.
::
$ pip install eemeter
Models:
Flexible sources of temperature data. See EEweather <https://eeweather.openee.io>_.
Data sufficiency checking
Model serialization
First-class warnings reporting
Pandas dataframe support
Visualization tools
Documenation for this library can be found here <https://openeemeter.github.io/eemeter/>_.
Additionally, within the repository, the scripts directory contains Jupyter Notebooks, which
function as interactive examples.
The OpenEEmeter project growth goals for the year fall into two categories:
A number of users have expressed how hard it is to get started when tutorials are out of date. We will dedicate time and energy this year to help create high quality tutorials that build upon the API documentation and existing tutorials.
As our user base grows, the need and desire for users to contribute back to the library also grows, and we want to make this as seamless as possible. This means writing and maintaining contribution guides, and creating checklists to guide users through the process.
Technical goals
1. Implement new OpenEEmeter models
The OpenEEmeter Working Group continues to improve the underlying models in
OpenEEmeter. We seek to continue to implement these models in a safe, tested manner
so that these models may continue to be used within engineering pipelines effectively.
2. Weather normal and unusual scenarios
The EEweather package, which supports the OpenEEmeter, comes packaged with publicly
available weather normal scenarios, but one feature that could help make that easier
would be to package methods for creating custom weather year scenarios.
3. Greater weather coverage
The weather station coverage in the EEweather package includes full coverage of US and
Australia, but with some technical work, it could be expanded to include greater, or
even worldwide coverage.
