ENERGY EFFICIENT INVESTMENTS INC.
ECM 6-—- Mini Splits
EEI proposes removing the (19) existing Mitsubishi ductless splits.
Furnish and install (19) new Mitsubishi condensing units of the same capacity of the existing system.
Counts are as follows: (7) 1-ton ceiling cassette systems, (3) 1.5-ton ceiling cassette systems, (1) 2-ton
ceiling cassette system. (1) 1-ton wall mounted system, (6) 1.5-ton wall systems, (1) 2-ton wall
mounted system. New units will be furnished with wind baffles for low ambient cooling and new wall
mounted thermostats.
IPMVP Option B, Retrofit Isolation with All Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameter changing in the implementation of this ECM is the mini
split Energy Efficiency Ratio (EER). EET will use current transducers to measure the EER for a 20% sample
of the mini splits over a one month period to obtain a representative loading profile.
ECM 7—- Condensing Hot Water
The current water heating units are standard efficiency. This measure would be to replace the current
system with high efficiency condensing Lochinvar units.
IPMVP Option A, Retrofit Isolation with Key Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameter changing in the implementation of this ECM is the
combustion efficiency. EEI will use a flue gas analyzer to measure each water heater efficiency before and
after ECM implementation.
ECM 8 -— Targeted Balancing
EEI proposes targeted balancing of the existing ventilation systems. When ventilation units are over -
ventilating it causes unnecessary conditioning of outside air. This measure would include checking the
air flow at the diffusers to ensure that it meets current code required flow.
IPMVP Option A, Retrofit Isolation with Key Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameter changing in the implementation of this ECM is the
airflow amount. EEI will use airflow hoods to measure a 20% sample of diffuser airflow cfm before and after
ECM implementation.
ECM 9- kitchen Hood
The existing kitchen exhaust system has a basic on/off operation. This results in the system operating during
times when it doesn’t need to be operating and heated or cooled air is exhausted. This measure is for
installing a Captive Aire unit with VFD drives on the kitchen hood exhaust fans. A temperature sensor will
be installed in the duct work and control operation based on the temperature inside the duct.
IPMVP Option B, Retrofit Isolation with All Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameter changing in the implementation of this ECM is the
kitchen hood exhaust fan speeds. EEI will use Energy Management System (EMS) trending data over a one
month period to obtain a representative loading profile.
