<br /> <br /> <br />“Page content is subject to Confidentiality Restrictions” <br /> <br />City of Arvada, Colorado | Project #37213 | M&V Report – Year 2 | Page 14 <br /> <br /> <br />City of Arvada, Colorado <br />Measurement & Verification <br />The M&V Plan for this ECM was based on a modified application of IPMVP Option A. In this case, the M&V Plan has an <br />asterisk next to Option A* in the EPC, and it states that “agreed upon savings that have been derived through <br />engineering calculations will be used to quantify the energy savings associated with this ECM.” This modified approach <br />uses the rated efficiency of the installed chiller to recalculate the agr eed upon savings. As mentioned above, the <br />installed IPLV is higher than the proposed value, which means a more efficient kW/ton was installed. <br /> <br />Ameresco confirmed that the chiller efficiency meets the expected values and that the sequencing of the new chil led <br />water plant is consistent with the design intent. Review of the Technical Data Sheet for the new chiller shows that the <br />installed integrated part load value (IPLV) of 17.42 is slightly higher than the proposed IPLV of 16.00. This leads to <br />additional savings from this ECM. The chiller Technical Data Sheet is shown in Appendix C. <br /> <br />Note: During the Year 2 site visit, Ameresco was informed that both chillers have been repaired after the phase loss <br />from the electrical service that occurred during a late-winter storm in March of 2022. This means 100% of the cooling <br />plant capacity is now available. During the visit, Chiller #1 was off and Chiller #2 was running at low -load, which was <br />the appropriate operation for the conditions. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
