Types of energy audit The term energy audit is commonly used to describe a broad spectrum of energy studies ranging from a quick walk-through of a facility to identify major problem areas to a comprehensive analysis of the implications of alternative energy efficiency measures sufficient to satisfy the financial criteria of sophisticated investors.  Four common audit programs are described in more detail below, although the actual tasks performed and level of effort vary.
   
Preliminary Audit The preliminary audit (alternatively called a simple audit, screening audit or walk-through audit) is the simplest and quickest type of audit.  It involves minimal interviews with site-operating personnel, and a walk-through of the business facility or home to become familiar with the building operation and to identify any glaring areas of energy waste or inefficiency.

Typically, we usually uncover major problem areas during this type of audit.  Many of the corrective measures are described in the attached documents with the auditing questionnaire, and simple payback periods are provided on items.

General Audit The general audit (alternatively called a site energy audit or detailed energy audit or complete site energy audit) expands on the preliminary audit described above by collecting more detailed information about facility/residential operation and by performing a more detailed evaluation of energy conservation measures.  Utility bills are collected for a 12 to 36 month period to allow the evaluation of the facility/resident's energy/demand rate structures and energy usage profiles.
General Audit +PLUS An audit to provide a system with the ability to zone the facility/residence according to how each room will be used, the ability to rate up to 10 stars, and a full range of climate zones across Australia.

If interval meter data is available, the detailed energy profiles that such data makes possible will typically be analysed for signs of energy waste.  Additional metering of specific energy-consuming systems can be performed to supplement utility data.

This type of audit will be able to identify all energy-conservation measures appropriate for the facility/residence. A detailed financial analysis is performed for each measure based on implementation cost estimates, site-specific operating cost savings, and the customer's investment criteria. Sufficient detail is provided to justify project implementation.

Investment-grade audit In most corporate settings, upgrades to a facility's energy infrastructure must compete for capital funding with non-energy-related investments.  Both energy and non-energy investments are rated on a single set of financial criteria that generally stress the expected return on investment (ROI).  The projected operating savings from the implementation of energy projects must be developed such that they provide a high level of confidence.  In fact, investors often demand guaranteed savings.

The investment-grade audit (alternatively called a comprehensive audit, detailed audit, maxi audit, or technical analysis audit) expands on the general audit described above by providing a dynamic model of energy-use characteristics of both the existing facility and all energy conservation measures identified. The building model is calibrated against actual utility data to provide a realistic baseline against which to compute operating savings for proposed measures. Extensive attention is given to understanding not only the operating characteristics of all energy consuming systems, but also situations that cause load profile variations on short and longer term bases (e.g. daily, weekly, monthly, annual). Existing utility data is supplemented with sub-metering of major energy consuming systems and monitoring of system operating characteristics.
