Hello, we are currently confused regarding the distinction between consumption and demand within the total energy cost saving calculation. All our investigations were based on the actual metered consumption. Does the distinction in the Reference Guide mean that seperate, theoretical demand calculations are required or does the demand just stands for the projected energy cost savings? It would be nice to receive some clarification, Thank you

Julia, Most utilities have two separate charges for electricity....one for demand charges (kW), and one for consumption charges (kWh). The LEED requirement makes you consider any cost savings associated with both reduced demand and reduced consumption, as you can't accurately calculate payback without consider all sources of cost savings.

Hi, Jenny, for the 25% process cost , how should we calculation the Process cost if a building with demand charges? Assume one building that the demand charges is 1$/year and the consumption charges is 3$/year, should I must get a 1$/year from consumption charges as process load if I use the 25% rule? Thank you so much.
