"Energy Balancing" How to Use the Energy Balance Data You Have Collected TO MAKE FINANCIAL DECISIONS
Abstract
This article extends the energy balance described in Part I of this
two-part series, “Analyzing Facility Energy Use: A Balancing Act,” pub-
lished in Strategic Planning for Energy and the Environment, Fall, 2001.
Once you know how much energy your various pieces of equipment are
using, you can then make informed decisions on what changes will
make that equipment operate more efficiently.
In this article, we describe ways to expand the basic energy balance
format to help select cost-effective energy saving projects. We also dis-
cuss the advantages of using various financial analysis techniques such
as Simple Payback Period, Savings-to-Investment Ratio, Internal Rate
of Return, and Net Present Value. We describe these techniques in an
extended energy balance spreadsheet.
