What is an Energy Audit?
An Energy Audit is detailed assessment on how electrical energy is being consumed within a site. It studies such aspects as energy usage, tariffs, lighting systems, load profiling, HVAC systems (heating, ventilation and air conditioning) and specific electrical devices and services.
An Energy Audit will benchmark all current levels of energy consumption. Once these levels have been established the Energy Audit will focus on areas where reductions can be achieved. An energy audit will enable organisations to demonstrate energy efficiency strategies improving their environmental responsibilities. The report will enable organisations to implement changes on a priority basis offering R.O.I (return on investment) estimations on all recommendations. In some industries government programs require organisations to participate in Energy Auditing on a regular basis. In circumstances where energy consumption is not being managed properly regulators may impose penalties.

Level 1
Walk-through audit: Preliminary analysis made to assess building energy efficiency to identify simple and low-cost improvements but also a list of energy conservation measures (ECMs, or energy conservation opportunities, ECOs) to orient the future detailed audit. This inspection is based on visual verifications, study of installed equipment and operating data and detailed analysis of recorded energy consumption collected during the benchmarking phase

Level 2
Detailed/General energy audit: Based on the results of the pre-audit, this type of energy audit consists in energy use survey in order to provide a comprehensive analysis of the studied installation, a more detailed analysis of the facility, a breakdown of the energy use and a first quantitative evaluation of the ECOs/ECMs selected to correct the defects or improve the existing installation. This level of analysis can involve advanced on-site measurements and sophisticated computer based simulation tools to evaluate precisely the selected energy retrofits

Level 3
Investment-Grade audit: Detailed Analysis of Capital-Intensive Modifications focusing on potential costly ECOs requiring rigorous engineering study.
