EXECUTIVE SUMMARYThe Massachusetts Division of Capital Asset Management (DCAM) and

Bridgewater StateCollege (BSC) selected Ameresco Select Inc. (ASI) to provide comprehensive

energy and waterconservation upgrades at Bridgewater State College, a state institution of higher

Educationlocated in Bridgewater, Massachusetts. The goal of this project is to reduce

energy and watercosts and provide capital improvements to the campus infrastructure.

Following is a timeline of milestones achieved:

RFP Issued April 2004 Contractor Selection March 2005 DEA Start March 2005 DEA Submittal January 2006 ESA Execution March 31, 2006 Contract Completion Date June 30, 2007 Actual Completion Date June 15, 2007 Final Project Notification August 28, 2007

EXECUTIVE SUMMARY (cont’d)Of the five options presented, DCAM and BSC selected ASI based on Option 2A:

20‑YearCentral Utilities. This option includes a comprehensive package of measures that

woulddeliver significant energy and water cost savings; provide valuable infrastructureimprovements; improve reliability and occupant comfort; provide electric

generation; andreduce the maintenance burden.

The scope of work completed, comprises a project of $10.7 million to implementthe

24 measures which deliver energy and water cost savings of $956,249. After debtservice,

the net annual savings to the College is $ 33,249. Table ES-1 summarizes theeconomics of

the program recommended by ASI.Table ES-1:Table ES-1:
