Energy auditing for existing buildings

An energy audit is a systematic examination of how your building and its systems use energy. A detailed energy audit can show you how much energy is used by each system and when the energy is used, which is invaluable information for developing an effective energy management strategy, and for identifying the most promising options for reducing your energy use and improving your energy efficiency. An audit can also help you assess the effectiveness of energy-saving measures after they have been implemented.

Energy audits can vary in complexity and from one organization to another, but every audit typically involves:

  • data collection and review
  • plant surveys and system measurements
  • observation and review of operating practices
  • data analysis
