4.6 Post-Installation M&V Activities
The points in the new EMCS system to be monitored for use in savings calculations are
listed in Table 4-5. All of these points will be “trended” — meaning that there will be a
time stamp associated with each recorded point value. From this information, the total
operating hours of the affected equipment for the year will be calculated. Temperature
data will be collected and analyzed to ensure that the operation of the control system is as
intended. Additional points will be collected for ECM 3 (Chiller) so that this information
can be used to verify the performance of that measure. A complete listing of the EMCS
system parameters will be provided in the Post-Installation Report, including:
• documentation of the actual EMCS installed, detailed sequences of operations, as-
built points list, and a summary of the EMCS operation features in regard to
control of the chiller pump and fan motors, and
• operation manuals for the EMCS and chillers.
