Walk-in Cooler Load Calc

Calculate the Q-Value (heat transfer) for the walls on this walk-in produce cooler. Remember that the U-Value is the reciprocal of the total R-value. If the walls were constructed with multiple types of materials, the formula for finding the total resistance would be the sum of the R-Values of all the materials. For example: Rt = R1 + R2 + R3 etc.
