Project Overview

1, PROJECT SUMMARY

The goal of this project is to achieve energy savings through upgrades to the buildings’
electrical, plumbing, mechanical, and building envelope. This project will result in improved
building performance, thereby reducing energy and maintenance costs.

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.

measure would include checking the air flow at the diffusers to ensure that it meets
current code required flow.

ECM 9- Kitchen Hood

The existing kitchen exhaust systemhas a basic on/off operation. This results in the system
operating during times when it doesn’t need to be operating and conditioned air is
exhausted. This measure is for installing a Captive Aire unit with VFD drives on make-up air
and exhaust fans. A temperature sensor will be installed in the duct work and control
operation based on the temperature inside the duct.

for commercial and industrial transformers supplying linear loads in the 30-150 kVA
range is 95%, as compared to 98% for a high efficiency model. Further, conventional
transformer losses, which are non-linear, increase by 2.7 times when _ feeding
computer loads.

EEI recommends the replacement of existing inefficient transformers in order to improve
the energy efficiency ofthe electricaldistribution systems through the replacement
of the transformers with new high efficiency units. The scope of work for this measure
would include:

Scope of Work:

Install (3,860) LED 2x4 and 2x4 retrofit fixtures with Spacewise control and wireless
dimming capability

Install (260) LED high bay fixtures with Spacewise control and wireless dimming capability
Install (642) LED recessed can fixtures

Install (2,947) LED tubes and (1,644) LED drivers

Install (193) LED lamps

Install (47) LED round decorative fixtures

ECM 2 —- Controls Upgrade

EEI proposes installing a complete DDC system as an extension of the existing N4
Enterprise Supervisor.
