WHY BILL COMPARISON DOESN'T Get the job done, OR, WHY USE Weather CORRECTION
Suppose you want to see savings from the new productive chilled water process you installed this January. A basic comparison of prior and submit charges ought to show the cost savings proper? Very well, not specifically. Suppose previous 12 months had a somewhat neat summer time, and this summer time was devilishly sizzling. Would you see the financial savings? Probably not.
There are a couple of ways we can plot the use from 12 months to yr. Suppose we just looked at the use vs. time, like most persons do.
We have marked two regions. The bottom (darker) area, we phone non-climate sensitive use. This use can be attributed to computer systems, lights, constant volume pumps and other loads that are on irregardless of what the climate is. For an all year operation, this quantity is regular. (In this scenario, the non-climate delicate use is rather minimal, considering that this meter serves a mechanical plant. Normally, the non-weather conditions delicate use would be larger.)
We simply call the prime (lighter) area weather sensitive use. This is utilization straight connected to, in this case, air conditioning the facility. Use in this region could be attributed to chillers, cycling chilled water pumps, cooling towers, condenser drinking water pumps, condenser enthusiasts, and perhaps followers and pumps that cycle or are on a variable frequency drive.
