CEA 2.2.3 Heat Loss/Gain Quiz

When calculating the total transmission load of a wall assembly, what is the value used for the change in temperature ( $\Delta$ T) if the outside temperature is 18 $\degree$ F and the desired temperature is 72 $\degree$  F?

(Just enter the number without any units)

Using the chart above, what is the value used to determine the R-Value of wall containing 6" brick?

• 0.20

• 0.80

• 1.20

• 6.00

Using the chart above, what value is used to determine the R-Value of 2 single-glazed windows? (Enter the value to 2 decimal places.)

Using the chart above, what is the value used to determine the R-Value of a wall containing 3/4" drywall?

• 0.225

• 0.45

• 0.675

• 0.9

What is the U-Factor of a double-glazed window that has a R-value of 1.67?

• 0.599

• 0.67

• 1.67

• 3.34

Using the information above, what is the R-Value for the wall that would result in a total heat transmission load of 628.5 Btu/H? 

 Remember:  $Q'=UA\left(\Delta T\right)$  

• 12

• 14

• 16

• 18

Using the diagram above, what is the R-Value for the entire Wall Assembly if the R-Value for Gypsum Wall Board is 0.9 per inch, Rigid Insulation Board is 5.0 per inch and the Clapboard Siding is 1.2 per inch?

Using the information in the chart above, which of the following insulation choices has the lowest U-Factor?

• 4.5 inches of batt insulation

• 3.5 inches of rigid board polystyrene

• 4 inches of batt insulation

• 4 inches of rigid board polystyrene

What value would be used for the area of a 16' x 8' wall containing 2 windows that measure 2' x 3'?

• 6 square feet

• 12 square feet

• 116 square feet

• 128 square feet

Using the information in the chart above, determine the total R-Value for the Roof Assembly.

(Round your answer to the nearest hundredth and do not enter in any units.)
