Energy Audits

The need to reduce energy costs is a crucial business practice for successful organizations, and energy audits have begun to play a more significant role in managing energy expenses. Energy audits can encompass a variety of surveying techniques but most commonly consist of an analysis of energy usage within a building or facility and its contained equipment. Energy audits can be ASHRAE Level I, II, or III for conditioned space, or comprehensive or tactical energy surveys for industrial facilities. Audits include comprehensive lists of energy efficiency measures derived from building and facility performance. Energy audits also include financial analysis for each identified measure. Energy audits can use information from building management systems (BMS) with the goal of reducing energy usage without negatively impacting the company’s everyday practices. Industrial energy audits often focus on key aspects of the overall system that tend to use the most energy. Common examples of audited equipment include HVAC, lighting, and plug load.

Energy Efficiency Measures

Energy efficiency measures do not operate in isolation from one another. Solar gain through windows that warms in the winter also heats in the summer and can be a source of glare unless controlled. Similarly, lighting efficiency measures affect the operation of heating and air conditioning systems in a building. Accordingly, planning for and executing retrofits should be done with a whole-building performance perspective to ensure cost-effective and efficient performance over the year - and for the long term.
