Frequently Asked Questions


How do I view my data and update "Date Meter Became Active?

To view your data:

  1. Log in to Portfolio Manager
  2. Select your property, then click on the "Energy" or "Water" tab
  3. Click on your virtual meter, then select "2018" from the "Display Year(s)" dropdown menu
  4. You should then see 2018 data for your building 

Note: Data for the past five years has been uploaded to your account, and you will need to change the date the meter became active to reflect the earliest date for which you have meter data.  

To change the "Date Meter Became Active":

  1. Go to the Energy or Water tab for the meter you want to edit
  2. Click on the name of the meter you would like to edit and you'll be taken to its Basic Meter Information page
  3. Expand the Basic Information bar
  4. Edit the "Date Meter became Active"
  5. "Save Changes"

Note: The first meter entry and the Date Meter became Active should align. If they do not align, you will see an alert (warning message) each time you save new meter entries.

What is a benchmarking report?

Per LADBS, a report, generated by ENERGY STAR Portfolio Manager, summarizing the whole-building energy and water performance of a building.

What software tool is used for benchmarking and reporting?

Per LADBS, ENERGY STAR Portfolio Manager is the free, online tool used for benchmarking and reporting. 

How often do I need to benchmark my building?

Per LADBS, buildings that are subject to the EBEWE Ordinance must be benchmarked every year by June 1st after the inital benchmark. 

How should I classify my property or building type?

Per LADBS, property owners can choose from the Portfolio Manager list of property use types to classify a property or building type. 

How do I benchmark if I have multiple buildings sharing a meter?

Per LADBS,  in Portfolio Manager, there is a feature called “Campus.” When you set up your property address, indicate that you have multiple buildings. Later in the process, you can specify a building ID for each building on the “Campus.” You must also calculate the water and energy usage for each building based on your best estimate of what each building uses.

I have less than 5 tenants with individual meters. One of the tenants refuses to sign a consent form required by LADWP. LADWP will not release the data. How can I still comply?

Per LADBS, you may estimate the water and electrical usage by comparing the benchmarked building with other similar buildings to the best of your ability.

An existing building was occupied for only a few months during the calendar year to be benchmarked. How do I benchmark it for 12 months?

Per LADBS, prorate the usage by taking a monthly average of the number of months for which you have data. Then use that data to estimate the remaining months for the year.

What is the difference between occupancy and vacancy?

Occupancy refers to the percentage of your property gross floor area that is occupied and operational. If you have people working in all floors/areas of your building then you are 100% occupied. You do not need to count empty cubicle spaces – but, you do want to make sure your number of workers is correct when tenant usage patterns change. Vacancy refers to a portion of the building that is not in use. This is not a few empty cubicles but rather a suite or entire floor that is not leased or occupied. When more than 10% of your property is vacant, you are required to create a separate “Vacant Space” property use for certain property types

Does occupancy rate affect my score, and how do I report changes?

The value you enter for occupancy rate will not affect your ENERGY STAR score or any other metric. However, this value could affect your eligibility for ENERGY STAR  Certification as certain property types have minimum occupancy rate requirements. You can adjust your occupancy rate on the "Details" tab under "Basic Information" in ENERGY STAR Portfolio Manager.

Energy & Water Audits and Retro-Commissioning

Do I have to get an energy and water audit?

Yes, beginning in 2021, building owners or representatives will have to prove that a building is energy and water efficient or that it is on a pathway to efficiency.  See Section 91.9708.2 for the schedule and more info on audits and retro-commissioning report compliance.

How often do I have to show my building is energy and water efficient?

Every five years after the initial deadline. Your initial deadline for showing performance is based on the assessor’s parcel number of your building.  View the schedule for audits and retro-commissioning report compliance here.

Are new buildings subject to the Ordinance’s performance requirements?

Energy audits and retro-commissioning are not required for buildings that are new and have been occupied for less than five years from their first due date, based on the Temporary Certificate of Occupancy, or Certificate of Occupancy. See Section 91.9706.2.3 Exemptions #4 in the Ordinance.
