Energy Audit - General Approach

Energy Audit : An inspection , survey and analysis of energy flows for

energy conservation in a building, process or system to reduce the amount ofenergy input into the system without negatively affecting the output(s). Audit Types depends on

Industry Type Intensity of audit required Magnitude of cost reduction desired
