Energy Conservation Measures (ECMs): Which Projects Should We Select?
Abstract
Completing an energy audit of a facility should provide us with
various candidate energy conservation measures (ECMs) . " Wh ich
Projects Should We Select?" is often asked. ECMs selected will be based
on your requirements, wants, needs and benefits.
This article discusses critical methodologies and procedures during
our selection process. Key steps include correct engineering and eco-
nomic analyses. The much used simple payback is shown to be a very
poor economic decision guide. If these analyses are not properly accom-
plished, inappropriate equipment and systems will be bought and in-
stalled. The result will lead to dire consequences. Information is pro-
vided to help energy managers and building owners make the right
decisions for selecting appropriate, cost- effective ECMs.
