ℹ EC = current energy consumption; AES = annual energy savings (EC − EP). For HVAC: Rating in Tons, Eff = EER. For Gas: Rating in MMBtu/hr, Eff = efficiency ratio. For Fuel Substitution: Rating = gal/yr per unit, Eff Current = $/gal, Eff Proposed = kWh/hr.

∑ Formula Reference
Electric Motor
EC = N×HP×0.746×H×RF×LF / ηc
EP = N×HP×0.746×H×RF×LF / ηp

HVAC / Chiller
EC = N×Tons×12,000×H / (EERc×1,000)
EP = N×Tons×12,000×H / (EERp×1,000)

Gas Equipment
EC = N×Q×H×RF / ηc [MMBtu]
EP = N×Q×H×RF / ηp [MMBtu]

Fuel Substitution
EC = N × gal/yr × $/gal [$]
EP = N × kWh/hr × H × Re [$]

AES = EC − EP
DR = AES × 12 × Cf / H
ACS = AES×Rₑ + DR×R_D + AES_gas×R_G
PBP = IC / ACS
ηc / ηp = current / proposed efficiency.
EER = energy efficiency ratio (Btu/W·hr).
Q in MMBtu/hr for gas equipment.
RF = running factor, LF = loading factor.
