Navy Activity-Level Energy Systems Planning Procedure (A-LESP) Users Manual

摘要

A-LESP is an evaluation procedure to rapidly identify and evaluate large numbers of energy conservation options. The options are defined in the Energy Conservation Opportunity (ECO) and Energy System (ES) sections of the manual. Evaluation of the energy options is accomplished in a three-step process: (1) Identify representative facilities/systems at the activity. As each facility identified, the feasibility of applicable energy options is evaluated, with feasible options listed for further consideration. (2) Establish the economic viability of the feasible options by using a simplified version of the savings to investment ratio(SIR) in which the present worth of the savings in energy operation and maintenance is divided by the present worth of the cost of the project. A method for determining this ratio is included with each energy option. and (3) Establish energy goal categories and funding sources for economically viable energy options (SIR > 1). The ECOs are functionally grouped into six sections: Building envelope; Distribution; Heating, ventiliation and air conditioning, Hot water, Lighting; and Equipment. The ESs are functionally grouped in three sections: Cogeneration; Steam; and Electric.
