Java Application for Heating and Cooling Load for a House

You will calculate the heating and cooling loads for a typical residence. The wintertime
heating load is all of the heat that flows out of the building when the outside temperature is
nearly its coldest and when there is no free heat provided by sunshine or internal lights or
appliances. The coldest time is typically in the middle of January. The summertime cooling
load is all of the heat that flows into the building when the outside temperature is nearly its
hottest, the outside humidity is high, there are no clouds to block the sun, and the building is
occupied with normal lighting and appliance usage. The hottest time is usually about 3:00
PM at the end of July.
Assume that four design parameters are constant: The winter indoor design temperature is
72°F, the summer indoor design temperature is 76°F, the summer indoor design humidity
ratio is 0.01 lbs of water vapour per pound of dry air, and the sunshine coming in through
west windows at the design time is 193 BTU/hr / ft2, this is the value at 3:00 PM on July 21.
