Energy Audit Basics - Types of Energy Audits

Energy efficiency experts generally recognize three levels of energy audits depending on the time and effort spent during the audit and analysis:

Level I, basic. This approach involves a cursory analysis of energy bills and a brief survey of the building to produce a rough estimate of how efficiently energy is used in the building. This level of effort will detect at least some of the "low-hanging fruit" and may suggest other options worthy of more study, but should never be viewed as comprehensive.

Level II, intermediate. This method provides a breakdown of how energy is used in the building as well as a broader range of savings options, including simple capital investments. It accounts for the "people factor" and its effect on uncertainty of savings, and also explores maintenance procedures and assesses any impacts savings measures may have on them.

Level III, advanced. This analysis digs into the details of any large capital projects you may be considering as a result of previous, simpler audits. Even more detailed data is gathered from field equipment, extensive test measurements are taken which may include spot-measurements and short-term energy monitoring, possible risks are assessed, and intensive engineering and economic analysis produces reliable estimates of project energy and financial performance with the high confidence needed for major capital projects.
