Frequently Asked Questions

• Q: Can this tool be used on a Mac computer?
  • A: Yes, the Companion Tool is compatible with Mac operating systems.
• Q: Is there a specific order to follow when using the tool?
  • A: It is recommended to follow the steps in sequence for accurate evaluation of building performance.

To gather stakeholder feedback on the proposed fuel neutral approach in the ENERGY STAR MFNC ASHRAE Path, simulated building performance data needs to be collected using the DOE Compliance Form and the new “Companion Tool”.
This document provides the specific steps to evaluate a building using the proposed fuel neutral approach.
Step 1: Download and open the “90.1 Performance-based Compliance Form”. It should open with the “Instrucons” tab visible. If you see a different tab, navigate to it by selecng the blue “Instrucons” tab at the bo©om of the spreadsheet.

Step 2: Go to the “General Informaon” tab. Use the screenshot as a guide to complete the missing cells. Select ENERGY STAR MFNC v1.1 or an earlier program version from the dropdown menu. Select either ASHRAE 90.1-2016 (for Version 1.1) or ASHRAE 90.1-2019 (for Version 1.2). Finally, select the correct simulaon program.
Step 3: Next, navigate to the “Contact Informaon” tab and enter your Project Name. The Project Name will also be the name of the CSV file exported.

Step 4: For the purposes of this comment period, there is no need to complete the other tabs. Navigate to the green “Results from [soLware]” tab and follow the instrucons provided there to upload your model data from the soLware (eQuest is shown as an example below.) For regularly submi«ng your projects to the MRO, you will need to complete the rest of the file.
Step 5: Navigate to the green “Compliance Calculaons” tab and scroll down to Table 7. Note the % improvement beyond ASHRAE 90.1-2016, or ASHRAE 90.1-2019 for Version 1.2, excluding proposed design on-site renewable energy and exceponal calculaons. The example shows 7.8% and 8.6% for cost and source energy savings respecvely.

Step 6: Proceed to the blue “Dashboard” tab.
Step 7: Scroll down the page unl you locate the opon labeled “Export Data.” Click on this bu©on to generate a CSV file containing the necessary data.

Step 8: Download and open the 90.1 Performance-Based Compliance Form Companion Tool. It will open onto the “Instrucons” page.
Step 9: Navigate to the “Instrucons for CF Import” tab. Click on “Import from the Compliance Form” and select the CSV file generated by the Compliance Form.

Step 10: Go to “Project Performance” tab. This sheet is where the energy calculaons will be found. Select the applicable program (ENERGY STAR MFNC Version 1.1 or 1.2) from the dropdown menu.
Step 11: Scroll down to Table 4 (Compliance Calculaons) and Table 5 (Fuel Neutral Compliance Calculaons). Table 4 shows the energy cost and source energy savings. This should match the Compliance Calculaons table in the Compliance Form from Step 5 above. Table 5 shows the new fuel neutral calculaon (under the “Cost $” column). These are the savings calculated when using the proposed fuel neutral approach.
Step 12: Please use these results to answer the quesons on the ASHRAE fuel neutral approach in the MFNC Stakeholder Feedback Form. Along with this form, please also submit the Companion Tool, Compliance Form, and either the Building Efficiency Characteriscs form or the MFNC Workbook. Thank you for your support of the ENERGY STAR MFNC Program. If you have any quesons about this guide or the proposed changes, please contact EnergyStarHomes@epa.gov and we will be happy to assist you.
