Formula Reference

Q_i = A × O% × V × 88

Infiltration flow rate (cfm)

Q_W = 1.10 × Q_i × ΔT_h × H_h

Heating season heat loss (Btu/yr)

AES_G = Q_W × EF / (η_h × 10⁶)

Gas savings (MMBtu/yr)

Q_Cs = 1.10 × Q_i × ΔT_c × H_c

Cooling season sensible load (Btu/yr)

AES_E = Q_Cs × EF / (EER × 1000)

Electric savings (kWh/yr)

EF (strip) = 70% | (AC) = 80%

EF (high-speed) = 1 − v_slow/v_fast
