Unit: BTU HL = Heat loss (BTU)= Hv x hours If loss for one day, H = 24 hrs If we are talking about a D days then H = 24 hrs x D (e.g. During February, H= 24 hrs x 28 days) In summary heat loss for D days is HL = (A/R) * AT* D days *24 hrs Home Heat Loss Calculation Table Use coldest month of Feb (28 days) average of 20 degree ºF outside. Assume inside temperature of the house is 70 °F
