Q

What is a performance specification?

A

Leave flexibility to the contractor, so long as the specification as built performs correctly

22
Q

Where are GFI outlets required?

A

Outdoors
Laundry areas
Garages
Crawl spaces
Hot Tubs
Basements
Kitchen Counters
Generally anywhere people often occupy that’s near (< 6’) from water

23
Q

Where are GFI outlets not required?

A

Attics
Hot water heaters
Living rooms etc

24
Q

If you double the distance of a light from it’s source, how much does the illuminance drop?

A

By a 1/4

Inverse-square law

25
Q

What are some common types of Class I vapor retarders?

A

Foil
Thick Polyethylene Sheets
Vinyl Wallpaper
Melamine

26
Q

What are some common types of Class II vapor retarders?

A

Some Plywoods
Some Latex Paints
Kraft Paper
Rigid Foam Insulation

27
Q

What are some common types of Class III vapor retarders?

A

Gypsum Wall Board
Latex

28
Q

What does a lower perm value mean?

A

Less vapor can pass through

29
Q

What does a high perm value mean?

A

More vapor can pass through

30
Q

What is the perm value range for a Class II vapor retarder?

A

0.1 - 1.0 Perms

31
Q

What is the perm value range for a Class III vapor retarder?

A

1 - 10 Perms

32
Q

What ratio do you want from each layer of a wall assembly?

A

10:1 perm ratio

33
Q

Between air infiltration and vapor diffusion, which is more likely to cause condensation?

A

Air infiltration

34
Q

When do you use grout in CMU?

A

To create a load bearing wall. Grout creates compressive strength

Rebar (horizontal and vertical) provides tensile strength

35
Q

When do you use vermiculite or perlite-filled CMU?

A

Increased thermal resistance, increased sound TL and improved fire rating

36
Q

Where is transverse bracing required in a seismic zone?

A

Ends of the duct runs, perpendicular to the travel of air flow

37
Q

What materials have high embodied energy due to their mining process?

A

Copper, aluminum and stone

38
Q

What are the best options for rubber gasketing?

A

Butyl rubber

EPDM

Silicone gaskets

39
Q

What is Styrene-Butadiene Rubber (SBR)?

A

Cheap syntheic rubber

Cheap and not strong or resilient over prolonger pressure

NOT USED IN CONSTRUCTION OFTEN

40
Q

what is Butyl rubber?

A

Synthetic rubber that is airtight, watertight, robust, thermally and chemically stable, sunlight/UV resistant and overall stout.

MOST EXPENSIVE

41
Q

What is EPDM?

A

Most water resistant

Resistant to abrasions and tears, stands up to weathering and breakdown from sunlight exposure, maintains resilience over prolonged pressure

42
Q

What is silicone?

A

Resists breakdown from sunlight exposure and maintains resilience over prolonged pressure.

Longer lifespan than EPDM, more stretchy, much better in lcations where it might get hot

43
Q

Rubber short hands

A

Butyl - best but expensive

EPDM - most water resistant, not good in hot climates

Silicone - best for hot climates

44
Q

What is the difference between a storefront and a curtain wall?

A

Storefront is typically limited to one story and sits inboard of the edge of the slab

Curtain wall drapes down the building like a curtain

45
Q

Where does the reinforcing go for a storefront”?

A

In the mullion

46
Q

What is a control joint?

A

Example is a shallow groove in concrete to control cracks from shrinkage

Gives the concrete a place to shirnk and crack, so you can control where those happen

47
Q

RoTs for expansion joint locations?

A

At changes in wall height or thickness

At columns, pilasters, and wall intersections

Near corners (within 10’ of one side of a corner)

On both sides of openings wider than 6’

On one side of an open smaller than 6’

48
Q

Where is delayed egress not permitted?

A

Assembly, Education, High Hazard

49
Q

What is the best conduit to use?

A

Aluminum

Steel if you’re burying it in concrete and want to pull wires more easily

PVC when you’re doing a wet location

NEVER COPPER

50
Q

What is the code prescribed maximum shear wall ratio?

A

3.5:1
