(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

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.

Introduction

This Measurement and Verification Plan has been prepared as a guide in determining the energy savings as a

result of the installed Energy Conservation Measures. In this document, EEI will show the baseline
calculations used to determine cost savings and how we can evaluate the installed measures to ensure the
Savings Guarantee is being satisfied.
