Q: Why is coincidental or non‐coincidental loads important.
A: If the auditor identifies two different ways to reduce loads at two different times of the day (not overlapping) this is non‐coincidental loads and they cannot be added together when trying to determine how much load can be reduced.
Example of non‐coincidental load:
Reducing Air‐Conditioning reduced load 100kW from 1PM‐3PM
Reducing Lighting 50% resulted in 100kW reduced from 4PM‐6PM
The auditor should report the maximum load reduction of 100kW.
Example of coincidental load:
Reduced Air‐Conditioning reduced load 100kW from 2PM‐4PM
Reduced Lighting 50% resulted in 100kW being reduced from 2PM‐5PM
The auditor should report maximum load reduction of 200kW.
