Data Collection
Energy Management Software collects historic and/or real-time interval data, with intervals varying from quarterly billing statements to minute-by-minute smart meter readings. The data are collected from interval meters, Building Automation Systems (BAS), directly from utilities, or other sources. Past bills can be used to provide a comparison between pre- and post-EMS energy consumption.
Electricity, and Natural Gas are the most common utilities measured, though systems may monitor steam, petroleum or other energy uses, water use, and even locally generated energy. A the renewable energy sources has contributed to the spurred growth in EMS data collection markets.

—Susan Sontag (b. 1933)
“It’s rather grisly, isnt it, how soon a living man becomes nothing more than a collection of stocks and bonds and debts and real estate?”
—John Dos Passos (1896–1970)
