∑ Formula Reference

Fs = (Ti − To) / (Ti + 460) × 100

MES = (HP × 0.746 × H × RF × LF × Fs) / (12 × η)

AES = N × Σ MES

DR = (AES / H) × 12 × CF

ACS = AES × RE + DR × RD

PBP = (IC − Incentives) / ACS

Fs = fractional savings from cooler intake air.
Ti+460 converts °F to °R (Rankine).
Summer months (May–Sep) use summer indoor temp.
