OBJ 3.4

Question 1

Compare and contrast storefront and curtain wall.

Answer 1

Storefront is a non-load-bearing entrance and glazing system designed for high use. A curtain wall is a non-load-bearing exterior wall that is hung from the floor slab above like a curtain.

Question 2

Weather barrier

Answer 2

Any material that will resist liquid (bulk) water intrusion. It is installed on the outside of a building and used to deflect liquid water that leaked, penetrated, or seeped past the exterior cladding. It is combined with flashing and other materials to direct water away from the exterior sheathing.

Question 3

Vapor retarder

Answer 3

Any material that is used in a building assembly to slow or reduce the movement of water vapor through a material. It is installed on the warm side of the insulation in a building assembly.

Question 4

Air barrier

Answer 4

A system of materials and construction methods used to control airflow between a conditioned space (interior) and an unconditioned space (exterior). Proper air barrier systems create a continuous enclosure around a building and impede the flow of air into and out of a space.

Question 5

Drainage board

Answer 5

Dimpled plastic sheet material applied along the vertical face of a foundation wall. The dimpled side is placed toward the foundation wall, creating a 1/2-inch (typically) cavity in which water from above can travel to drains at the foundation footing.

Question 6

Flexible flashing

Answer 6

Term used to describe a broad category of nonmetallic flashing, including peel-and-stick and nonstick flashing. Typically used to seal the perimeter of openings within a wall assembly (windows, doors), but it can be used along the base of walls, parapets, and corners of buildings. The inherent flexibility of the material allows it to conform to unusual shapes and angles.

Question 7

Recommended air space behind masonry veneer walls

Answer 7

One-inch minimum used in conjunction with dedicated drainage plane material.Two inches recommended to ensure mortar or other debris does not cause blockage.

Question 8

Common building pollutants

Answer 8

Dust and pollen, tobacco smoke, mold and mildew, hazardous materials, perfume, VOCs, radon, sewer gas, formaldehyde, methane, pesticides, bird and rodent droppings, asbestos, lead, and carbon monoxide.

Question 9

FFE

Answer 9

Furniture, fixtures, and equipment. Movable furniture, fixtures, or other equipment that has no permanent connection to the structure of a building.

Question 10

Cut and fill

Answer 10

The process of keeping excavated soil on a site by designing grading that equalizes the amount of grade that is removed (cut) with the amount of grade that needs to be added (filled), thereby reducing the requirement to transport soil off the site.

Question 11

True or False? American folk houses of the Victorian era were designed around allowing as much light as possible into the spaces.

Answer 11

False.

Question 12

The _______ era coincided with increased use of mechanization.

Answer 12

Victorian.

Question 13

The craftsman style of the early 20th century was a reaction to the ________ of the Victorian era.

Answer 13

Overindustrialization.

Question 14

As people age, what physiological effects can make it harder for them to interact with their environments?

Answer 14

Pupils narrow and lenses get thicker and cloudier, making it harder to see and requiring more light than younger people to see the same thing. Older people are also more sensitive to intense light and glare. Hearing loss, usually within a certain range of tones, occurs over time so that people don’t always notice it. Loss of elasticity in some tissues, making it harder to breathe and reducing oxygen in the blood supply. Loss of muscle mass, leading to loss of dexterity and flexibility. Loss of nerve cells, reducing the amount of information that can be processed, slowing response time, and inhibiting coordination. Memory loss.

Question 15

Guardrail

Answer 15

A barrier placed at locations where there is a vertical drop of 30 inches or more, such as on stairs, landings, the edge of mezzanines, porches, balconies, and decks. Guardrails should be a minimum of 42 inches high and must resist a point load of 200 psf applied at any point in any direction. Guardrails must be designed to not allow a 4-inch sphere to pass. Loading docks and the edge of a stage are not required to have guardrails, but any adjacent stairs would need them. Guardrails are not to be confused with handrails.

Question 16

Post and beam construction

Answer 16

Using posts, beams, and planks as framing members. The spacing of the members is farther apart than conventional framing.

Question 17

Stick construction

Answer 17

Using stick framing members to build on-site. For example, building a roof out of wood rafters instead of prefabricated trusses.

Question 18

Pole building or pole barn

Answer 18

A type of building with no foundation that is constructed from posts spaced about 8 feet apart and girts and a skin to tie it together. Common for agricultural buildings.

Question 19

Pre-engineered metal building

Answer 19

A building of rigid steel frames, girts and purlins, and a panel cladding. Metal buildings are inexpensive ways to enclose large, column-free spaces. They are also called engineered metal buildings.

Question 20

Parquet flooring

Answer 20

A geometric, wooden mosaic floor pattern composed of wooden planks and rotated to form a pattern, often comprising squares.

Question 21

The vapor barrier is located on the ___________ side of insulation.

Answer 21

Warm. By placing the vapor barrier on the warm side, it can inhibit condensation from reaching the dew point by restricting the transmission of water vapor.

Question 22

Masonry units

Answer 22

Include stone, brick, CMUs (concrete masonry units), and clay tile blocks.
