Instructions:
Use this template as a starting point for an end-use breakdown (end-use disaggregation).
(1) Estimate the energy consumption of end-use systems in the buildings and enter these estimates
into the appropriate column in the table. Spaces for inputs are marked in blue text.
For a Level 1 analysis, these estimates may be based on expected equipment densities or
estimates based on similar buildings.
For a Level 2 or Level 3 analysis, the end-use estimates for major end uses may be based upon
one of the following:
(listed from most accurate to least accurate)
a) Detailed measurements of end uses, measured over time
b) Spot measurements of end uses, with estimated hours of operation
with analysis to support annualization of the measured data
c) Detailed calculations or hourly simulations of equipment performance based on
manufacturers' specifications or design drawings
d) Assumptions of typical end-use densities
(2) Input the historical energy consumption for your building.
Replace the inputs in blue text with data for your billing, including the end-use estimates, the
building gross floor area (in units of your choosing), and the historical billing data totals for
comparison. These inputs should be consistent with the historical energy use
used as part of the Preliminary Energy-Use Analysis Template.
(3) Replace the sheet titles with your own. Note project name, date, etc.
(4) Use the space below the table to document your assumptions or to note conclusions that can be
derived from the data.
(5) You may need to add additional end uses for your building, if they are significant.
For example, if the template were used for a data center, you would want to include a separate line
item for input power supplied to uninterruptible power supplies (UPSs). It is the auditor's
responsibility to chose end-use categories that are meaningful for the building. These are listed
for guidance as typical end-use categories.
(6) Delete rows in the end-use table that are not necessary for your building. This will eliminate blank
labels on your chart.
The remaining cells will be calculated as a result. A sample sheet is included for your reference, or you may
begin from the blank copy.
