Title
Summary/Description of
module: Should include a short technical history of the
potential application of the energy conservation opportunity module
as applied to energy and monetary savings.
General Rules of Thumb: (will vary
according to module type: should include rules of thumb
typically observed in industry where energy efficiency is effectively
practiced. The following shows a typical example applied
to a lighting recommendation. Tables and graphs containing
data essential to a recommendation calculation should be included
here and targeted to increase the speed of data access.
- The average cost of electricity is $0.05/kWh
- There are 2000 hours per year per shift
(based on the assumption that one shift is 8 hours per day,
5 days per week, 50 weeks per year)
- Average cost of lighting: The
following table gives operating costs and light output data
for various lighting types. The tabulated data include ballast
contributions.
- Lights generate heat at a rate of
3.4 Btu/hr/watt of energy consumed.lESNA

Notes: (The following notes
should be common to most modules unless it contains a more comprehensive
pay back period and implementation protocol.)
Before choosing the following targeted recommendations
READ THE FOLLOWING: Pay
back estimates for the following recommendations will use the equation
below. They will vary depending on the, application, type of installation,
and purchase quantity of material and labor associated with each
recommendation. It will be up to the person doing the analyses
to use the URL references below each equation to help estimate an
implementation cost.
The data correlating to the variables below
each equation will be prompted for in order to execute a calculation.
Frequently the fuel cost (FC) associated with the specific recommendation
will be prompted for in order to calculate the annual cost savings
(ACS). Unless otherwise specific to a particular recommendation
the ACS will be calculated as follows:
(This section should contain targeted recommendations that are
related to the module topic. Once they are chosen the cursor
moves to the appropriate recommendation for calculation.)

Variable description: Should include
variable definitions with correct units, how data should be
acquired, and equipment needed to collect data.
Also may includes links where data can accessed for a specific
calculation.
N = number of fixtures/lamps/ballasts to be removed
EU = energy use per fixture/lamp and/or ballast, BTU/hr
LH = number of hours lighting is used per year
Calculation resources: Should include active
calculator, active data conversion table, links to data tables
and graphs at the top of the recommendation
