The Role of the Energy Audit in Reducing Building Energy Consumption

The application of the energy audit process to the reduction of energy consumption in buildings is described. A methodology for selecting from an inventory of buildings those buildings which are candidates for a detailed energy audit is presented, and the analysis of energy consumption and cost savings resulting from implementation of energy conservation opportunities (ECO\u27s) is detailed. A practical payback period formula is presented which includes escalating energy costs. The audit and analysis procedures are illustrated by two case studies
