Heat Loss Calculations
Q = AU(delta)T
A=area of material U=1/R-value of material (delta)T =temperature differential
Total area of walls = 16,575.32 ft sq
Total area of windows = 323.2 ft sq
Total Area of doors = 84 ft sq
Take each area and divide it by the R-value for the material.
Walls - 10.175 = 1,629.02
Windows - .88 = 367.27
Doors - .88 = 95.45
Total = 2091.74
Multiply by the temperature differential. (outside temp during summer-desired temp, and then the same time for winter temp.)
average winter = 72 - 22 = 50
average summer = 72 - 70 = 2
Add these values together and add a blog entry showing the BTUH for each material and the total BTUH for the structure.
Building BTUH during winter = 104,587 BTUH
Building BTUH during summer = 4,183.48 BTUH
