Thread-topic: [EnergyPlus_Support] Proper use of R-squared evaluation for energy use

Niraj,

Thanks for the offer!

I normally try to make one fuel correlate well with actual metered consumption. (This is normally gas, because it has less factors affecting it.) Then I work on the other one, finally reviewing both for believability. That’s why I use separate the R2 values plus the overall.

p.s., The spreadsheet I’ve attached has been copied from a much larger one so that you don’t have to wade through all of the other data needlessly. I think it includes all relevant data and formulae. Note that all energy use is made unitary (per square foot of floor)
