How to Conduct an Energy Audit

11/15/2010

Sophisticated energy analyzers introduced in the 80s were able to trend and record energy usage and help identify when, where, and how much electrical

energy was being used. However, due to limited user-interface capabilities, these analyzers printed to paper tape and tended to be complex to operate. At that time, the cost of an energy analyzer was approximately $5,000, which translates to well over $10,000 today. For these reasons energy audits and surveys were limited to medium to large industries that could justify the investment in the instruments as well as the time necessary to conduct the surveys and analyze the results.
