The Energy Savings Opportunities section allows auditors to enter and report energy savings opportunities identified during the energy audit. This is a two-step process:

  1. Enter individual Energy Efficiency Measures (EEMs) in the Building Energy Saving Opportunities – Measure tab.
  2. Designate packages of EEMs in the Building Energy Savings Opportunities-Packages tab.

Note: Only EEMs assigned to a package will appear in the Building Energy Savings Opportunities Summary tab and the downloadable PDF report.

To learn more about how to create measures, refer to WA Commerce Grants Report Building Energy Savings Opportunities - Measures.

Package Guidance

All EEMs must be assigned to a package.

To create a new package:

  1. Enter the Package Name
  2. Select the Recommendation Category from the dropdown menu.
  3. Choose the first measure from the dropdown (the drop down is populated with Measure Identifiers from the Energy Saving Opportunities -Measures)
  4. Click the green “Add Energy Savings Package” button to add it to the table.
  5. Click Save/Refresh to update the table.

To add more measures to an Existing Package:

  1. In the “Add Energy Savings Measure to Packages” column, select the target package you already created and wish to add more measures to. Select the measure to add from the drop down.
  2. Click “Add Energy Savings Measure” button
  3. Save/Refresh the table.

Definitions and Calculations

Annual Energy and Cost Savings

  1. Total Cost Savings
    The total energy cost savings estimated through water conservation measure.
  2. Peak Demand Savings
    The total savings in peak demand costs for the year.
  3. Fuel specific Energy Savings
    The total annual energy savings achieved. The units depend on the fuel source.
  4. Carbon Savings
    Estimated reduction in CO2e emissions resulting from energy efficiency measures implemented in the building.

Payback with Incentive

  1. Package: Initial Incremental Investment Cost
    Initial Investment Costs refer to the expenses incurred during the planning, design, construction, and/or acquisition phases of a project. These costs are typically incurred before a building is occupied or a system becomes operational. They do not include future costs related to operation, maintenance, repair, replacement, or general use of the facility or system during its service life. Incremental Initial Investment Costs represent the additional upfront costs associated with an alternative option compared to the base case.
  2. Package: Total Incremental Investment Cost
    Total Incremental Investment Costs include the additional initial investment cost required for alternative, additional capital replacement costs required for alternative and account for the additional residual value attributable to the alternative.
  3. NIST 135-2020 Simple Payback
    Simple Payback is a financial metric used to evaluate the cost effectiveness of a retrofit. It is the ratio of the incremental initial investment cost to the annual total energy cost savings. The resultant value is the time (in years) a retrofit measure may take to pay back its initial investment cost. The simple payback calculation shall be in accordance with NIST Handbook 135, Section 6.4.4, Equation 6-13.
  4. NIST 135-2020 Savings to Investment Ratio
    The Savings-to-Investment Ratio (SIR) is a financial metric used to evaluate the cost-effectiveness of an investment. It is a ratio of the energy cost savings to the total incremental investment cost.
