Use this section to enter and report the recommendations determined by the energy auditor in the order of highest operational priority or return on investment. Energy Efficiency Measures (EEM) may be entered into a table as a part of a package in one of two recommendation categories: Low Cost and No Cost, and Potential Capital. This table may be used to report energy and cost savings, and incentives for entered EEMs, and will display calculated payback and ROI values for EEM packages. Total costs and energy savings for all of the measures will automatically be calculated and displayed.
Note: Packages should only include measures from the same End Use Category and/or that affect the same system. For example, enter measures associated with the Measure Categories of boiler plant improvements and lighting improvements as separate packages; and enter HVAC measures for air handler units vs. packaged terminal units as separate packages.
For New York City Energy Efficiency Reports, select the Building Energy Savings Opportunities screen to enter EEMs that apply only to a specific BIN. Select the Shared System Energy Savings Opportunities screen to enter EEMs that apply to shared systems within the BBL. Shared systems may include HVAC heating, cooling, or condenser plants, or service hot water systems entered in the Facility Description section. Entries and edits made to the tables on this screen will auto-populate the records of all of the BINs in a BBL.
To create entries in the energy savings opportunities tables, select Low Cost and No Cost or Potential Capital from the Recommendation Category drop down menu and press the green Add button. You may create and assign and/or edit a custom Package Name to a measure entry or a group of entries, or accept the default counter values (e.g. Package 1, Package 2). Complete package and measure entries by completing the following sections below. Add measures to packages by selecting the blue Add Measure button.
Measure Name and Description
Select end use and measure categories from the drop down menu lists, which will populate lists of associated EEMs to select from in the Measure Name drop down menu. Select an appropriate EEM from among the list of actions required for implementation.
Note: Some EEMs may apply to multiple end use categories. For example, EEMs under the measure category of building envelope modifications may apply to heating, cooling and air distribution end uses. The End Use Category is not a required field and may be left blank, particularly when entering measures which impact more than one end use.
Use the ‘Measure Status’ dropdown to categorize each EEM as a recommended measure or a practical measure (by selecting ‘Not Recommended’). This can also be used to identify if a measure has been implemented already or requires additional analysis. Provide a description of the existing conditions that provide background for understanding the basis for each recommended measure as necessary, in the Description text field.
For New York City Energy Efficiency Reports, if Heating, Cooling, Air Distribution, Water Distribution, or Domestic Water Heating is selected from the End Use Category drop down menu, then any previously entered applicable systems will be available from the drop down Shared System menu. Upon selection, the BIN numbers associated with the shared system will be visible for the EEM.
EEMs that do not apply to a shared system but are included as part of a shared energy savings recommendation package may be entered and identified by selecting ‘No’ in the Applies to Shared System field and entering the implementation costs for each measure.
Example: Heating package that includes a measure to replace a boiler that is located in building 1 but shared between buildings 1 and 2 (Applies to Shared System = Yes); and a measure to insulate the boiler room in building 1 (Applies to Shared System = No).
Annual Energy and Cost Savings
Indicate whether the savings for each measure were identified manually via spreadsheet calculations or with an energy modeling software by selecting from the Modeling/Calculation Approach drop down menu.
Energy and cost savings are to be entered for the package of measures and not for every individual measure. Energy savings for each package needs to be identified for each of the energy supply sources which are affected by the measure. Enter one input per package for the following: the total annual cost savings, the cost savings by energy source (electricity and/or gas/fuel), and the peak electric demand savings, if available.
Note: measures that have negative savings may be entered as part of a package, with the negative savings factored in to the cost savings calculations.
For New York City Energy Efficiency Reports, savings are to be estimated and entered for the system level (multiple BINs), not the building level (single BINs).
Payback with Incentive
Provide a summary of the implementation cost for each measure. Enter one input per measure for the following: measure cost and potential incentives (in dollars), and measure life (in years). The potential incentives should include the available utility, tax or other incentives applicable to each measure.
The payback of each package of measures will automatically be calculated using the following formulas:
Net Measure Cost = Total Measure Cost - Total Potential Incentives
Simple ROI = Total Cost Savings/Total Net Measure Cost
Simple Payback (in years; excluding incentives) = Total Measure Cost/Total Cost Savings
Simple Payback (in years; including incentives) = Total Net Measure Cost/Total Cost Savings
Totals of the energy and cost savings, and the measure costs for all of the recommended measures in the table are automatically calculated and displayed on the bottom row of the table.
Terms and Definitions
The following definitions for content appearing in this section have been referenced from Standard 211:
energy efficiency measure (EEM): an action taken in the operation or equipment in a building that reduces energy use of the building while maintaining or enhancing the building’s safety, comfort, and functionality. The term is sometimes known as energy conservation measure (ECM).
interactive effect: The change in resultant energy savings estimates or actual energy savings due to analyzing or implementing multiple energy efficiency measures (EEMs) which impact one another.
Low Cost/ No Cost measures: Low cost/no cost measures are those that can be implemented within the O&M budget for the facility, where such exists.
practical measure: An EEM that is determined to be technically feasible.
recommended measure: A practical measure that has been vetted for interactive effects with other practical measures and determined by the qualified energy auditor to provide net benefit to the building ownership. Life-cycle Cost Analysis (LCCA) may be used as the methodology to filter Practical Measures to Recommended Measures.
simple payback: Estimated initial energy efficiency measure (EEM) cost divided by the EEM first-year calculated cost savings. Both savings and costs are in dollars ($) or other consistent monetary units, and the simple payback is expressed in years.
simple return on investment (Simple ROI): The energy efficiency measure (EEM) first-year calculated cost savings divided by estimated initial EEM cost. Both savings and costs are in dollars ($) or other consistent monetary units.
