Your family just bought a very small cabin in Estes Park, CO, and they have asked you to help figure out heating costs for the building, Since your grandparents plan to stay at the cabin often and they like it warm, you decide that you need to be able to achieve 23 "C in the winter. Assuming a minimum heat output of 2 people. 2 lamps, a TV, a computer and a refrigerator, you've figured out that a reasonable estimate for total internal gain rate is 600 W. You calculate that the whole building heat transfer coefficient for the existing cabin is 400 W/K. Note that some questions may have values that are randomly generated and will change on second homework attempts. You will need to revise your mathematics, but the methodology and formulas remain the same.
