Questions:

LU: 1 HS: 1

1. Thermal and moisture protection performance criteria are important to building envelope design because of all except which of the following?
a. Leaks in an air or vapor barrier can be a potential source for moisture control failure.
b. Many city, state, and national codes are requiring better thermal barriers within the building envelope
c. Mold and health concerns are unrelated to thermal and moisture protection, and liability.
d. Moisture can condense and remain in the wall cavity, creating an environment for mold to grow.

2. What are the three elements comprising point supported, bolted glass
systems?
a. Countersunk bolts, prefabricated trusses, mullions
b. Storefront stainless steel frames, concealed bolts, tempered glass
c. Heavy float glass, concealed hinges, aluminum space frames
d. Structural supports, glass, and fittings

3. Attributes of composite mullion curtain wall systems include all except
which of the following?
a. Can only be inside-glazed under certain climate conditions
b. Decreased field labor
c. Better thermal performance
d. Reduced glazing time

4. The Light to Solar Gain (LSG) value of solar glass outperforms high
performance solar control Low-E glass and clear insulating glass.
a. True
b. False

5. Aluminum composite material with high strength organic fiber is designed
to withstand which condition?
a. Exploding vehicle bomb near large window expanses of a blast curtain wall
b. Bullets and blasts originating within 30 feet of the building envelope
c. Category 4 hurricane, wind speeds to 155 mph
d. Category 3 hurricane, wind speeds to 130 mph

6. Which best describes the main function of aluminum composite material
with high strength organic fiber?
a. Bullet resistance for exterior cladding systems on buildings considered to be terrorist targets.
b. Protect building facades from the impact of flying debris during hurricanes.
c. Provide blast resistance protection from vehicular bombs outside a building.
d. Allow large expanses of insulated or solar glass to be installed 30 feet above ground level.

7. Liquid applied flashing systems create a seamless condition because:
a. The components form a chemical bond.
b. The liquid is applied to a peel and stick membrane and then cures.
c. The components form a mechanical bond.
d. Only highly trained, certified laborers can install it.

8. Which of the following is not a factor that typically leads to greater liability
and risk?
a. Thermal performance and moisture control
b. Different warranties from different manufacturers within a single system
c. Multiple trades, contractors, materials and manufacturers on the jobsite
d. One source for multi-component building envelope systems

9. Recent developments relating to point supported, bolted glass include all
except which?
a. Concealing countersunk bolts
b. Increasing nickel sulfide content, to strengthen glass and reduce breakage
c. Create safer heavy float glass through the heat soaking process
d. Minimizing roller wave distortion

10. Which of the following statements is not true about insulated metal
composite panels?
a. When engineered for thermal performance and moisture control, they can reduce mold-related risks.
b. Pre-fabricated panels typically reduce job site scrap.
c. Approximately $3 billion in building mold related claims were paid in 2005.
d. Reflective coatings for high solar reflectance on building envelope systems can lower building cooling costs.
