* Based on Linear Feet of outside wall TOTAL HEAT LOSS PER °F BTU/HR/°F
Multiply total BTU/HR/°F X 30 and plot on the graph below at 40°F. Draw a straight line from
the 70 base point thru the point plotted at 40°F. The intersection of this heat loss line with the
unit capacity line represents the winter design heating load.
