The energy auditing process can be separated into two main steps:
Results from energy audits provide insight for building owners and also identify the most economical and energy-saving opportunities. Audits alone do not decrease energy usage; energy-saving strategies must actually be applied in order to see results. However, the implementation of these cost-effective opportunities can result in a payback period typically ranging from six months to four years, depending on the savings approaches utilized.
Any existing building is a candidate for an energy audit, but especially those that consume excessive energy, are considering building upgrades, or have never before been audited.
