A 5,000 SF exterior wall is made of six (6) inches concrete of transmittance (U) of 5.0 BTU/ Hr. SF.*F, four (4) inches of brick of transmittance (U) of 0.2273 BTU/ Hr. SF.*F, two (2) inches of insulation of resistance (R) 13 BTU/ Hr. SF.*F, and one-half (1/2) inch of GWB of resistance (R) 0.32 BTU/ Hr. SF.*F. Ignore the resistances of the outside and inside air films. The temperature difference is 70 degrees F. (a) What is the Total Resistance, R (b) What is the Total Heat Loss, Q?
