This area of EnergyIQ provides a list of potential energy upgrades tailored to your building(s), enabled by the information you enter in Features. While upgrade recommendations are available for both the California (CEUS) and U.S. (CBECS) peer group buildings, savings estimations are only available for CEUS.

You can sort these recommendations by clicking on the column headings. You can also filter the recommendations by clicking on the Filter link on the top-left corner of the table.

To see more and more plausible upgrades, click on a building name and enter more Features so that we can better estimate the eligibility of your building for a particular upgrade.

For more information on the methodology behind this process, visit our engineering documentation.


END USE: Each measure is associated with a top-level end-use (e.g., Lighting), corresponding to the end-use choices on the Benchmark tab.


ACTION: We select actions from a library of 35 possible upgrades, a total of 132 efficiency-level variations.


BUILDING: You can generate recommendations for one or more of your buildings, as described in the My Buildings tab. The default will be the first (alphabetical) building in your My Buildings list.


POTENTIAL SAVINGS: The savings are derived from computer simulations of each actual building in your peer group (as selected by you on the Benchmark tab). Savings can be show in terms of site energy, source energy, electricity, peak electricity demand, fuel, carbon emissions, or money. The three values shown reflect the range of outcomes for the simulations of your peer-group buildings, i.e., for the 25th, 50th, and 75th percentiles. The savings values  are expressed in  percentage of whole-building savings. Rigorous savings estimates require an investment-grade energy audit. The sort key for this column is the 50th percentile value.


In some cases, savings can be negative.  These can happen where non-HVAC measures influence HVAC energy use.  Electric lighting savings, for example, can cause increased gas use for heating (as well as cause increased whole-building electric savings thanks to reduced cooling loads).


ROI: This column provides a rough qualitative sense (low-medium-high) for the return on investment of each measure.


STATUS: This field indicates the status of the recommendation. The choices are: Pending, Accepted, Implemented, Rejected, and Not Applicable.


ADD NOTE: You may add specific notes to any measure by clicking on the “Add Note” button.  Deleting a note will restore the button.
