1. ENERGY STAR Portfolio Manager Overview
ENERGY STAR® Portfolio Manager® is the United States Environmental Protection Agency’s (US EPA) online tool for measuring and tracking of energy and water consumption.
For information on how to sign up for ENERGY STAR Portfolio Manager, create a building profile, etc., please visit: https://www.energystar.gov/buildings/benchmark.
The Energy Usage Data System (EUDS) provides monthly energy usage data that can be submitted directly to ENERGY STAR Portfolio Manager from within the EUDS. This guide will present the steps to connect a building between the EUDS and an existing ENERGY STAR Portfolio Manager profile. The high-level steps are as follows, with detailed instructions provided further below:
2.Initial ENERGY STAR Portfolio Manager Connection
Connecting your EUDS building to ENERGY STAR Portfolio Manager is a multi-step process between the EUDS and ENERGY Star Portfolio Manager. We recommend opening separate web browser tabs to complete the process.
2.1 Connect with Data Exchange ComEd (COMEDABS)
2.2 Download your ENERGY STAR Property
We recommend downloading a copy of your ENERGY STAR Portfolio Manager property. Once a connection is set up between the EUDS and ENERGY STAR Portfolio Manager, any existing data in the ENERGY STAR Portfolio Manager meter that the EUDS is mapped to will be overwritten.
To download your building’s current ENERGY STAR property:
2.3 Create a New ENERGY STAR Portfolio Manager Meter
To create a new meter:
2.4 Connect Your Building Between ENERGY STAR Portfolio Manager and the Energy Usage Data System
On the ENERGY STAR tab, you can view the ENERGY STAR Property ID, Meter ID, and sync status. The EUDS will synchronize the last 24 months of data to ENERGY STAR Portfolio Manager daily.
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.
You cannot make changes within the EUDS to make these errors go away. Errors must be addressed within the ENERGY STAR Portfolio Manager. For further information on ENERGY STAR Portfolio Manager alerts, please visit https://www.energystar.gov/buildings/tools-and-resources/list_portfolio_manager_alerts.
Once the EUDS building has successfully synchronized with the ENERGY STAR Portfolio Manager property, the metrics on the building’s Overview page will populate. “Gross Floor Area,” “Energy Star Score,” “Source EUI,” and “Primary Function” will now be populated with information from your ENERGY STAR Portfolio Manager property.
3. Troubleshooting Connection Issues
This section will walk through troubleshooting steps should you have difficulty connecting to ENERGY STAR Portfolio Manager.
3.1 Connection Status: No Properties Shared
The ‘No Properties Shared’ message indicates that you have successfully connected your account with Data Exchange ComEd (COMEDABS), but have not shared a property, or the property has been shared with the wrong Building Manager or Building IDs.
To share a property with Data Exchange ComEd (COMEDABS), see Section 2.4 Connect Your Building Between ENERGY STAR Portfolio Manager and the Energy Usage Data System.
To modify the Building ID or Building Manager ID, you must remove the connection with Data Exchange ComEd (COMEDABS) and re-share the property.
3.1.1 Removing a Property Share:
3.2 Connection Status: No Meters Shared
The ‘No Meters Shared’ message indicates that you have connected your ENERGY STAR property to the EUDS, but a meter has not been shared or the wrong permissions have been granted.
To modify the share settings for an already shared property:
3.3 Finding your Building Manager ID
Your Building Manager ID is a unique ID used for connecting to ENERGY STAR Portfolio Manager.
To find your Building Manager ID:
Each building in your portfolio will have a unique ID used for connecting to ENERGY STAR Portfolio Manager.
To find the building ID:
4. Disconnecting Meters and Properties
Disconnecting a meter from within EUDS will terminate automatic syncing to the ENERGY STAR meter but will not remove any usage data that has already been synchronized.
To disconnect an ENERGY STAR Portfolio Manager meter from your building:
Disconnecting your ENERGY STAR property from within EUDS will terminate automatic syncing to your ENERGY STAR Portfolio Manager property and will remove all share settings with EUDS. Disconnection will not remove any already synced usage data from any previously shared meters in ENERGY STAR OR any ENERGY STAR metrics that are displayed within EUDS.
Please note: Buildings that are deactivated by an Operational Administrator will be automatically disconnected from ENERGY STAR (properties and meters).
To disconnect an ENERGY STAR Portfolio Manager property from within EUDS:
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):
OR
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 as 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://www.energystar.gov/buildings/benchmark/understand_metrics.
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 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 further information on the difference between Site and Source energy, please visit https://www.energystar.gov/buildings/benchmark/understand_metrics/source_site_difference.
