Energy and Air Quality Conference

April 5, 2004

Innovative financing, support, and solutions for Implementing Energy Projects

Energy Services Companies

Turn key approach to energy and water conservation

Audits, engineering, project management, construction management, financing, and ongoing measurement & verification of savings

Energy Performance Contracting

A method to make facility improvements paid from guaranteed savings in energy* and operating budgets.

Virginia, Maryland, and the District have passed specific legislation to support Performance Contracting for public agencies.

*Including water and sewer savings.

Typical Building Problems

Inefficient operation Old equipment Ventilation problems Hot and cold spots Noise

Typical Conservation Measures

Lighting retrofits Control system upgrades Building management systems Chiller and boiler replacements Air handling system modifications Distributed generation Renewable energy

Project Development

Client and ESCO agree on general project scope. Utility usage baselined Facilities surveyed for operating characteristics and

conservation opportunities ESCO creates list of recommendations with cost, savings,

and potential financing options. Client and ESCO agree on scope of work Contract is negotiated Financing is obtained Project begins

Project Funding

Budgeted Capital Bonding Municipal Lease ESCO ownership Grants and rebates Other sources

Measurement & Verification

FEMP standards dictate four M&V choices Typical project includes a mix of utility bill

monitoring, metering, and stipulated savings Baseline is established during CEA and is matched

to the expected post implementation M&V approach.

The type of conservation measures and cost will guide the development of the best M&V approach
