3.3 Metrics Sync Errors

Once your profiles are synchronized between the EUDS and ENERGY STAR Portfolio Manager, any metrics errors present on your ENERGY STAR Portfolio Manager profile will also be pushed to the “Metrics Sync Status” section on your building’s ENERGY STAR® tab in the EUDS.

Most errors must be addressed within the ENERGY STAR Portfolio Manager, however, below are some commonly seen errors and how they can be rectified.

↑ Return to top

3.3.1 Insufficient data for Baseline or Current Date

• You have gaps

ENERGY STAR Portfolio Manager requires a full calendar year to calculate metrics. Ensure that the usage request you’ve submitted begins in January OR that the ENERGY STAR® virtual meter contains a full calendar year of usage. See Section 3.2.3.1 of our Building Owner User Guide for information on how to submit a usage request.

If you are using a virtual meter that has usage data provided from another source, and the meter entries use real bill dates, you may need to prorate usage, as the EUDS utilizes ENERGY STAR Portfolio Manager’s calendarization method. See https://energystar.my.site.com/PortfolioManager/s/article/How-does-Portfolio-Manager-calendarize-bills-1748912950876

• You have overlaps

Review your ENERGY STAR Portfolio Manager virtual meter to ensure there are no overlapping meter entries

• Your “Date Meter became Active” is AFTER some of your bills, so those bills are ignored

The “Date Meter became Active” should coincide with the earliest meter entry that you’re able to provide, even if your building’s physical meter has been active prior to this date.

• Your “Date Meter became Inactive” is BEFORE some of your bills, so those bills are ignored

If you have multiple meters that are being included in metrics, you should ensure that there are no overlaps and that the “Date Meter became Inactive” coincides with the last available meter entry.

• You haven’t entered 12 full calendar months of data

ENERGY STAR Portfolio Manager requires a full calendar year to calculate metrics. Ensure that the usage request you’ve submitted begins in January OR that the ENERGY STAR® virtual meter contains a full calendar year of usage. See Section 3.2.3.1 of our Building Owner User Guide for information on how to submit a usage request.

5. ENERGY STAR® Portfolio Manager® Information

ENERGY STAR® Portfolio Manager® is an interactive resource management tool that enables you to benchmark the energy use of any type of building. It is known as the industry standard for benchmarking commercial buildings. ENERGY STAR® Portfolio Manager® metrics allow you to compare your building’s energy use to a yearly baseline, national medians, or similar buildings in your profile.

5.1 ENERGY STAR® Portfolio Manager® Metrics

To view a building’s ENERGY STAR® Score and building Source Energy Usage Intensity (EUI):

1. Navigate to the Overview page for the building whose ENERGY STAR® score and EUI you would like to view. The ENERGY STAR® score and source EUI can be found at the top of the Overview page.

OR
2. Navigate to the Buildings page. From here, you can view the ENERGY STAR® Score and Source EUI for each building in your building list.

↑ Return to top

5.1.1 What is an ENERGY STAR® Score?

The 1 – 100 ENERGY STAR® Score is populated once complete and accurate energy and property detail information is entered into an ENERGY STAR® Portfolio Manager® building profile. An ENERGY STAR® score of 50 is the median, so a score above 50 means your building is performing better than 50% of its peers, while a score below 50 means your building is performing worse than 50% of similar buildings nationwide. A score above 75 or higher designates a building is a top performer, making it eligible for an ENERGY STAR® building award. An ENERGY STAR® score helps you assess how your building is performing and allows you to identify which buildings in your portfolio should be targeted for upgrades or recognition.

Further information on ENERGY STAR® scores can be found here: https://energystar.my.site.com/PortfolioManager/s/article/Calculation-for-ENERGY-STAR-score

↑ Return to top

5.1.2 What is Energy Use Intensity (EUI)?

There are two types of energy usage intensity (EUI): Site EUI and Source EUI. Site energy is the amount of heat and electricity consumed by a building as you would see on your energy bills. Source energy represents the total amount of raw fuel that is required to operate the building, including transmission, delivery, and production losses. Energy Use Intensity is expressed as energy per square foot per year. Site EUI uses the site energy per square foot per year, while Source EUI uses the source energy per square foot per year.

The U.S. EPA has determined that Source EUI is the most equitable unit of evaluation, therefore, this is one of the metrics the EUDS pulls back from an ENERGY STAR® Portfolio Manager® building profile.

For futher information on the difference between Site and Source energy, please visit: https://energystar.my.site.com/PortfolioManager/s/article/What-are-Site-Energy-and-Source-Energy-1748912950362
