ENERGY EFFICIENT INVESTMENTS INC.
EEI recommends the replacement of existing efficient transformers in order to improve the energy
efficiency of the electrical distribution systems through the replacement of the transformers with
new high efficiency units. The scope of work for this measure would include upgrading:
32 Transformers
(5) ISKVA
(4) 30 kVA
(2) 45 kVA
(1) 75 kVA
(6) 112.5 kVA
(1) 145kVA
(1) 150kVA
(1) 175 kVA
(3) 220 kVA
(4) 225 kVA
(2) 300 kVA
(2) 500 kVA
IPMVP Option B, Retrofit Isolation with All Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameters changing in the implementation of this ECM are the
transformer losses. EEI will use current transducers to measure the losses for each transformer over a one
month period to obtain a representative transformer loading profile.
ECM 5- Retro Commissioning
This is an allowance for an engineerig and maintenance team to install, repair, and replace any
damaged existing to remain equipment. Existing AHUs will include software revisions to reduce energy
consumption. Includes 5 years of analytics reports.
IPMVP Option C, Utility Data Analysis of Whole Building, has been chosen for this ECM. This option
has been chosen because the wide ranging effects of Retro Commissioning on building energy
performance does not lend itself to isolation measurement. EEI has established the building baseline
energy usage using utility data, see “Baseline Development and Performance Period” section. The
building energy usage will continue to be recorded after the ECM implementation and compared to the
baseline to determine savings. The savings guarantee is contingent on several building operations
factors described in the Conditional Savings Guarantee section later in this report.
