4. Calculate the heat losses through the above grade and below grade walls for one side of a house located in Hoboken, NJ, as shown in the sketch below, when the indoor air temperature is 68F and the outdoor temperature is 25F. Also determine the auxiliary heat required in February to overcome the heat losses through these walls. Assume that the DD base = 60F. Ignore any heat losses due to infiltration. - 25 ft. 4ft x 5ft Window with clear double glazing and operable wood/vinyl frame Typical 2 windows 10ft. 8ft Below Grade Basement Wall with Uniform R-10 Insulation Page 4 2x 6 Studs @ 24" O.C.
