Energy Audits and How to Get One September 30th, 2015

In these days of uncertainty, it is important to keep operating expenses to a minimum. One difference between companies that weather these difficult times and those which do not, will be that the survivors will have reduced their unnecessary expenditures before it is too late.

Unnecessary costs include costs for energy you don’t need to use. In the past, many companies have just considered utilities as “a cost of doing business.” By running an inefficient building, you are overpaying your utility for energy. It just doesn’t make any sense.

A good building energy audit will point the way to reduce your energy costs by 10% to 40%. For large organizations, this can be substantial and could mean the difference between staying afloat and going under. A professional technician, often called an Certified Energy Auditor (CEA), can give your office or building an inspection.

The Energy Audit Process

While each audit is a bit different, the process typically goes something like this:


  • Auditor visits the building and walks through your space

    • Room-by-room (or zone-by-zone)

    • Inspect your lighting, air conditioning, heating and ventilation equipment, controls, refrigeration, air compressors, water consuming equipment, and anything else that is using energy

Data collection

  • Using a notepad or iPad, the auditor takes inventory

    • Examination of past utility bills

    • Interview your facility manager

    • Depending on the type of the audit, the auditor may take measurements of temperatures, pressures, light levels, power draw, and other things

Cost-benefit analysis

  • Once the data is collected, the auditor performs a cost-benefit analysis for retrofitting with more efficient equipment

    • A description of the existing conditions

    • A description of the proposed energy conservation measure (ECM)

    • Expected annual savings associated with the ECM

    • Expected cost to implement the ECM

    • Simple payback and/or other financial measures, such as return on investment or life cycle savings


The time spent performing the walkthrough and analysis varies depending on the size of the facility and complexity of the energy systems.
