Building IQ DIY

The “Do It Yourself” Guide to Benchmarking Your Own Building

Welcome to the Building IQ DIY Hub

This page will walk you through how to comply with Building IQ from benchmarking to reporting. Download this How-To Guide for more information. If you get stuck, reach out to CORE anytime. We’re here to help. The requirements for DIY participants are the same as those working with CORE:

  1. Get an energy assessment if you have not had one in the last 5 years. CORE’s commercial Walkthrough meets the requirement and it’s FREE. 

  2. Benchmark your building using Energy Star’s Portfolio Manager. Building IQ starts with the biggest buildings – 20,000 sq ft. and above* – and rolls out to smaller buildings in subsequent years. Before getting started, find out when your building is required to be benchmarked in the “Benchmarking FAQs ” on the City’s Building IQ page.

  3. Report energy and water usage data to the City. Covered buildings are required to submit their benchmarking report by Dec. 1, 2022.

    Building Performance Standards are the next phase of Building IQ. Get a head start improving your energy and water efficiency. Learn more at the bottom of this page. 

Step 1: Create an ENERGY STAR Portfolio Manager Account

You will need to create an ENERGY STAR Portfolio Manager account to complete your benchmark and report to the city. Click the sub-steps in each section for screenshots and details:

C. Make Your Account Searchable
In the box asking “Do you want your Account Name (and username) to be searchable by other Portfolio Manager users?” choose “yes

D. Create Your Account
Then hit “Create My Account”


Why does my Portfolio Manager account need to be searchable?

Making your account sharable enables automatic data uploads from the utility, allows you to share your account with CORE or the City and makes reporting simple.

Step 1 Tips

  • Write down your username and password. Once you choose a username, it can’t be changed.
  • You can generate a Data Collection Worksheet to help you identify building information and data required for steps 1 through 3.

Step 2: Add a Property to Your Portfolio Manager Account

In this step, you will enter information about your property, how your space is used, the size, and more attributes. 


What if my building has a parking garage?

If your property includes a parking garage, you will need to account for it. Use the Parking Garage Reference Manual to make sure this is done correctly.

What is the Unique Building Identifier (UBID) and where do I find it?

The Unique Building Identifier (UBID) is a number the City of Aspen will use to link your property and data when it comes time to report. You can find your UBID on the City of Aspen’s Building IQ page.

What if my building has multiple uses?

Go to the “My Portfolio” tab. Find “Add Another Type of Use,” and then click “Add.” This will open a different list of attributes for that space type.

Step 2 Tips

  • Leave plenty of time for this step. Once you start, there is no way to save progress until you finish adding the property.
  • Gather the following information ahead of time: Square footage, type of property, address, occupancy, and how and how frequently your building is used. You can generate and print a Data Collection Worksheet to work offline.
  • If you have a parking garage, it needs to be included. Use this Parking Garage Reference Manual to account for it correctly.

Step 3: Add Utility Meters and Manually Enter Data in Portfolio Manager

This is where you enter your property’s energy and water usage from the past 12 months. You will need utility data from every source of energy and every meter. Click the sub-steps in each section for screenshots and details:

B. Select the different energy sources your building uses and how many you have of each.
  1. Check the applicable fuel type (electric, natural gas, water, etc.) boxes for all meters
  2. Provide any additional requested information (such as whether the electricity is purchased from the grid or generated onsite)
  3. Enter the the number of meters for each

E. Add your energy and water usage data
  1. Use the “How to Gather Utility Data” section below. 
  2. Click “Click to add an entry,” enter each month’s usage for all 12 months for that meter
  3. If you have tenants that pay their own utility bills, make sure to visit the FAQs in this section for more information on data gathering.
  4. Repeat for each type of meter and click “Continue”

F. Verify the meters entered to account for total energy and water usage
  1. Check the boxes for each meter
  2. Check “these meters account for the total energy/water consumption for this property.”

How to Gather Utility Data

Read this if you have tenants that pay their utility bills

If the owner pays the utility bills for the whole building, or there are four or more tenant meters the utilities can provide aggregated data for the whole building directly to the owner or their designee.  This data is also available from bill copies if the owner is able to obtain them. If this applies to you, skip to the instructions for gathering data from each utility in the following drop downs.

Buildings with three or fewer tenants that pay their own utility bills will have to gather utility data from their tenants. This can be accomplished by the tenant submitting the proper data consent forms for each of their water and energy utility providers. For water and other city utilities, tenants will reach

From the City of Aspen

Fill out the City of Aspen Utilities Data Consent Form to receive your building’s water and, if applicable your electrical consumption data and then email it to

Note, ALL BIQ participants receive your water through the City of Aspen Utilities and should fill out the City of Aspen Utilities Data Consent Form, regardless of your other energy providers.

From Black Hills Energy

Black Hills Energy (BHE) has set up a process that allows building owners to apply for energy usage information that can be provided to the state or local governments.  

  1. Visit Energy Usage for Large Buildings webpage.
  2. Register your building – complete and submit the form 
    1. Confirm all addresses are associated upon receipt of the Building Association email from BHE.  
    2. If any addresses are missing, reply to the email with the missing addresses.  
  3. Request Energy Use data through the Energy Benchmarking Form Request – complete and submit the form 
    1. If applicable, check the box verifying permission has been received from tenants to provide their usage data for aggregation purposes. If the building has 3 or fewer tenants, permission is required. 
    2. Confirm all addresses are accounted for upon receipt of Energy Benchmarking Report email from BHE. 
    3.  If any addresses are missing, reply to the email with the missing addresses.


How do I account for solar panels or other renewable energy generated on-site?

The electricity use from onsite solar and wind must be reported and included in your total energy consumption and ENERGY STAR score calculation. The use of onsite renewable electricity is part of your overall site energy consumption (i.e. the energy requirement of your property). A property with onsite solar or wind power is likely to receive a higher score.

You can enter this into Portfolio Manager when setting up your meters. Obtain data from your installer on the energy used, any energy exported out to the grid, and about any renewable energy certificates generated. If you report your renewable energy generation and use accurately, it will be reflected in your building’s greenhouse gas emissions. For additional details on green power, see this document.

Step 3 Tips

  • Gather the last 12 months of utility bills in advance if you are not using Data Release Forms. You will also need this info for your energy assessment or Building IQ Walkthrough.  
  • “Date Meter Became Active” will be the date of the first-meter bill reported for the building.

Step 4: Check for and Correct Data Errors

Once you have added all of your building information and energy and water usage data, Portfolio Manager will help you check to make sure it’s accurate. 


Can I run the Data Quality Checker more than once if I make changes?

Yes. You may rerun the Data Quality Checker as many times as it takes to correct all of the errors.

Building Performance Standards

Once you understand how your building uses water and energy, it’s time to start using resources more wisely. That is where Building Performance Standards–AKA BPS–come into play. 

BPS is a policy that requires building owners to meet performance targets for energy use by actively improving their buildings over time. Since the majority of commercial and residential building stock that will be standing in 2050 is already built, BPS will help accelerate carbon-reduction at the rate necessary to meet local and national climate action goals. From a building owner’s perspective, BPS provides flexibility as owners can use whatever technologies and operational strategies they decide are most effective and economical to meet the target. Multiple state and local governments have passed BPS policies, including Washington D.C., New York City, St. Louis, and Colorado and Washington states.
The BPS policy details for the City of Aspen have not been defined, yet. We are interested in getting feedback from community stakeholders and will be starting stakeholder engagement beginning in 2022 with the goal of collecting input to implement policies the following year, in 2023. CORE provides technical and financial resources to help aid in the process. Check out our grants and rebates to receive funding for energy efficiency projects.
