Quiz #1

Question 1

What are the five basic physics properties needed to understand BS?

Answer 1

Heat flows warm to cold
Moisture flows warm to cold
Moisture flows more to less
Air flows from high pressure to low pressure
Gravity acts down

Question 2

What are the six measurable building characteristics?

Answer 2

Durability
Moisture Management
Energy Efficiency
Indoor Air Quality
Structural Performance
Occupant Comfort

Question 3

Define Moisture Management.

Answer 3

Moisture management is an adequate control of water as it infiltrates the building. (Not prevention, but control.)

Question 4

Explain protected vs. unprotected structures.

Answer 4

Unprotected structures have the floors coming through to the exterior and stopping the wall. Protected structures have the exterior wall continue all the way up and the floor is stopped before the insulation to give a continuous thermal barrier.

Question 5

What are the four design functions in every building? What must they do/resist?

Answer 5

Support functions
Distribute functions
Control functions
Finish functions
These functions must resist exterior loading, interior loading, and the enclosure itself.

Question 6

Define support functions.

Answer 6

Distribute and transfer all physical loads.

Question 7

Define distribute functions.

Answer 7

Transport or flow into, within and/or out of the building. Ex. allows air pressure to equalize in a wall.

Question 8

Define control functions.

Answer 8

Into or out of the building, with respect to environmental loading. Ex. allow water to get in and out

Question 9

Define finish functions.

Answer 9

Appearance and/or suitability (durability).

Question 10

What are typical examples of exterior loading?

Answer 10

Main ones are:
Temp.
Solar
Precipitation
Others:
Humidity
Wind

Question 11

What are typical examples of interior loading?

Answer 11

Main one:
Relative humidity
Others:
Heat/cold
Fire
Mould
Air pressure
Water (Ex. pool)

Question 12

At a basic level what is the primary function of the building enclosure?

Answer 12

To separate the exterior and interior environments.

Question 13

What are the six regions of Canada?

Answer 13

Pacific
Cordillera
Prairie
Northern
Arctic
Southeastern

Question 14

Explain the pacific region.

Answer 14

Warm winters, lots of rain, more precip. in winter than summer

Question 15

Explain the cordillera region.

Answer 15

On mountains, cold winters, moderate summers, lots of precip. but is consistent

Question 16

Explain the prairie region.

Answer 16

Very cold winters, lots of wind, high wind chill, warm-hot summers, low avg. amount of precip.

Question 17

Explain the northern region.

Answer 17

Very cold winters from early Oct. to mid May, summer moderate, short, northern areas have perma-frost

Question 18

Explain the arctic region.

Answer 18

Bitterly cold winters from early Oct til mid May, break summers only breaking freezing, many areas have perma-frost, average precip., during winter is dark for 20hrs/day

Question 19

Explain southeastern region.

Answer 19

Sometimes very cold in winter, mild springs, crisp autumns, long warm-hot summers, lots of precip in east coast, avg. in Ontario

Question 20

What are the requirements of the building envelope?

Answer 20

Essential:
control air flow,
heat flow,
light, solar and other radiation,
entry of rain/snow
*water vapour
performs during service life
     provide strength and rigidity
     *be durable
     be economical
Others:
control noise
control fire
be visually pleasing
