Jan 12,200 – 10,200 + -1,200 = 800
Feb 9,600 – 11,200 + 2,320 = 720
Mar 8,800 – 7,800 + -200 = 800
Apr 4,400 – 4,800 + 1,280 = 880

Note that in this example the savings reported are for operations un-
der post-retrofit period conditions. Therefore the savings can be called
“avoided energy use.”
Option D Example: Calibrated Simulation Multiple ECM Project
Situation
An energy efficiency project was implemented in a university li-
brary building, involving four ECMs spanning lighting, HVAC, operator
training and occupant awareness campaigns. The building is part of a
multiple building campus without individual building meters. As part
of the energy management program steam, electricity and electric de-
mand meters were installed on the main supply lines to the library. The
objectives of the project were to reduce energy costs in the library.
M&V Plan
An M&V Plan was developed showing that Option D was to be
used for savings determination because baseyear data did not exist for
