Review of project progress/evolution
Initial project recommendations
Questions/Discussion/Input
Next actions and timeline
3. 3 What is the CCC-IOU EE Partnership?
A unique energy efficiency program; administered by the four IOU’s. The program is intended to:
Improve CCC facilities and lower operating costs at campuses statewide
Allow the CCC to leverage the local bond dollars and statewide project funding
Consist of several components focused around efficiency and education:
New construction and retrofit projects
Retro-commissioning projects
Training and education projects
Emerging Technologies
Through this incentive program, the utilities will offer administrative and technical support. Utilities will also be responsible for verifying the savings and the project at completion.
This program is funded by the California rate payer and administered by the four public IOU’s under the auspices of the California Public Utilities Commission.
4. 4 Overview of the CCC Program (Continued)
What is the timeline?
The program will run from January 2006 to December 2008
The project applications for the Community Colleges will begin on October 15th and run through November 15th of 2005
Projects will go through a two form process: Form One (Initial) and Form Two (Detailed Project Proposal)
The Project Forms will be applicable to all Retrofit, New Construction, Retro-Commissioning and Emerging Technologies Projects.
Project Implementation will begin January 1, 2006
5. 5 The need for energy modernization
Aging equipment and systems that waste energy
Air quality requirements that must be met
Rising maintenance costs on chillers, boilers
Control of escalating electric and natural gas costs
Demonstrate environmental leadership to the community
Consistent with master plan and included as a bond project
6. 6 Review of Project Progress/Evolution

Riverside campus – Costs and savings under development
Investigation results: Investigation has shown that the current technology and costs make a viable project challenging. If future rebate levels increase and technology improves, the viability may become favorable.
19. 19 What other projects did NORESCO investigate?
Cogeneration: Analysis showed marginal financial results for the Norco and Moreno Valley campuses; waste heat could not be consistently used. The Riverside campus is under review. High current prices for natural gas pose a significant challenge.
Water conservation: Most interior plumbing fixtures are currently efficient; some opportunity exists for irrigation water management
Re-Cycling: An opportunity exists if a third party contractor can be located that will assume 100% responsibility without cost
Thermal Energy Storage: The CCC/IOU Program does not offer targeted incentives but the option may become more viable in the future
