How to Conduct an Energy Audit Using the Energy Platform EP1

White Paper Introduction 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 costContinue reading “How to Conduct an Energy Audit Using the Energy Platform EP1”
