3. The movement of moisture (water or water vapor) from inside or outside a building may be caused by: Required Question

	Gravity
	Suction of water through building materials
	Water vapor diffusion and/or movement in air
	All of the above

4. To protect against condensation, all of the following may be effective EXCEPT: Required Question

	Avoiding cooling interior spaces below monthly average dew-point temperatures
	Locating cold-water pipes within insulated wall cavities
	Using high-performance glazing and insulative sheathing on steel framing
	Providing thermal breaks in aluminum frames for windows and curtain walls

5. Air barriers are important for moisture control in buildings because: Required Question

	They reduce air infiltration, a cause of moisture condensation
	They improve overall energy efficiency of the building envelope
	Tight building envelopes limit weeping of excess rain
	Air infiltration helps dry out building materials

6. Which of the following statements is the most accurate with regard to the impact of geography and climate on building envelope design? Required Question

	Buildings in warm and cold climates tend to have the same internal and external moisture loads
	Buildings in warm, humid climates have high internal moisture loads, and those in cold climates have high external moisture loads
	Buildings in warm, humid climates have high external moisture loads, and those in cold climates have high internal moisture loads
	For buildings in warm and cold climates, the moisture load is independent of internal and external sources

7. Which step is NOT recommended in developing the design of building envelopes that resist moisture intrusion? Required Question

	Identify the climate
	Determine potential moisture transportation mechanisms
	Select moisture control strategies
	Specify only building materials with permeable surfaces

8. Rainscreen façades are becoming more prevalent in the United States in part because they: Required Question

	Reduce complexity in designing for moisture control
	Eliminate the maintenance challenge of re-applying sealant
	Are now allowable by code
	Eliminate the requirement for an air barrier

9. Roof assemblies are most likely to fail … Required Question

	at perimeters and penetrations
	before walls and foundations fail
	when perimeter flashing laps over the top of the parapet
	due to condensation and moisture migration

10. True or false: Air barriers are now required in Canada, but not for any commercial building projects in the United States. Required Question

	True
	False

11. Two areas of construction detailing that are important to moisture control in the building envelope are: Required Question

	Carpeting and hung ceilings
	Footings and caissons
	Sealants and flashing
	Door hardware and window hardware

12. Perimeter flashing for window openings should have dual layers of subflashing, because: Required Question

	Single layers eliminate the support for the flashing material
	The window may become unstable and allow moisture migration
	Triple layers of subflashing tends to be too costly to install
	Single layers are more likely to fail and leak, especially at sill/jamb corners
