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:
30 Transformers
(6) 15 kVA
(2) 45 kVA
(2) 75kVA
(8) 112.5 kVA
(3) 150 kVA
(5) 220 kVA
(1) 225 kVA
(2) 300 kVA

ECM 2- Controls Upgrade
EEI proposes installing a complete DDC system as an extension of the existing N4 Enterprise
Supervisor.
Scope of work:
Demo the existing VAV controllers, keeping the existing communication wiring operational for the
existing controllers. Install new BACnet IP DDC controllers, new space sensors, and new discharge air
sensors. Install network controller hardware and software updates as needed.

ECM 1- LED Lighting
The schools currently utilize a combination of T8 and TS fluorescent lighting. EEI proposes replacing the
existing fixtures with new LED lighting. EEI performed a detailed survey of the interior and exterior spaces
in order to identify opportunities in which we can improve lighting quality, reduce maintenance costs, and
save energy.
