About EnPI Lite and Energy Performance Calculators

The Energy Performance Indicator Tool Lite (EnPI Lite) is an online regression-based calculator for modeling energy performance at the facility level. EnPI Lite has been designed to follow the 50001 Ready Measurement and Verification Protocol, which follows a top-down approach for determining facility-wide energy performance based on energy consumption and relevant variables.

EnPI Lite is recommended but not required to meet the 50001 Ready energy reporting requirement. For your initial 50001 Ready designation, energy reporting recommendations and requirements are as follows:

1. The recommended approach for all participants is to submit an EnPI Lite Output File, using the baseline and reporting year guidelines as described in the Navigator.

EnPI Lite accepts inputs from the Energy Footprint Tool and EPA's ENERGY STAR Portfolio Manager to perform regression-based modeling.

Visit EnPI Lite for detailed instructions on how to use the tool.

2. If you are a Better Plants partner, the next recommended approach is to submit your most recent Better Plants Annual Report with data reported at the facility level. If you do not have access to your most recent Better Plants Annual Report at the facility level, complete the 50001 Ready Baseline Reporting Template below.
3. If you are a Better Buildings Challenge partner, the next recommended approach is to submit your most recent Better Buildings Challenge Annual Report with data reported at the facility level.

If you do not have access to your most recent Better Buildings Challenge Annual Report at the facility level, the next recommended approach is to use Portfolio Manager.

If you do not use Portfolio Manager, complete the 50001 Ready Energy Consumption Baseline Report below.

4. If you use Portfolio Manager, use the 50001 Ready Energy Report for Portfolio Manager report template.

Participants will need to run the report for one full year of data, with the starting date being no more than 23 months from the submission date. It is recommended but not required for the data to cover the 12 months leading up to the implementation of the EnMS.

ENERGY STAR Energy Performance Indicator reports may also be submitted.

5. All participants are permitted to use the 50001 Ready Energy Consumption Baseline Report.

Download the 50001 Ready Energy Consumption Baseline Report, also available in the 50001 Ready Navigator (Task 24 - Task Overview).

The Period Covered should be one full year, with the starting date being no more than 23 months from the submission date. It is recommended but not required for the Period Covered to be the 12 months leading up to the implementation of the EnMS.

This form is valid only for initial 50001 Ready recognition.

For all reports, a separate form should be created for each facility requesting 50001 Ready recognition, or relevant facility data must be clearly indicated within the document. If multiple facilities are listed in a single document and not clearly identified, they will be assumed to be covered under a single scope for a single 50001 Ready designation.

For subsequent 50001 Ready designation renewals, participants will be required to demonstrate energy performance improvement.

If your facility uses an energy reporting form approved by a utility- or state-sponsored program, please Contact Us to inquire if it is an acceptable format to satisfy reporting requirements.
