Practice Test 1 Flashcards
Single zone all air system
best use in larger scale building
includes a large AHU unit, ducting, filters, and retain air systems
single zone does not allow for control by individual units
local unitary air conditioning unit
not energy efficient
noisy
combine heating and cooling in one unit (packaged) or a few sections (split)
very common
local air-to-air heat pumps
more energy-efficient than local unitary air conditioning unit
allows for individual user autonomy
transfers heat from outside air to inside of building to provide both heating and cooling. extracts heat from outdoor air and moves it inside through a refrigerant system
indirect evaporative cooling
lowers air temp by causing water to evaporate
uses a heat exchanger to cool air supplied to a living space
requires more infrastructure in terms of equipment, filters, pipes, ducting
does not allow for individual control of climate
quarter sliced wood
cut log in quarters on a 45degree angle
linear grain pattern
plain sliced veneer
cut log in slices, directly across
large, varying in size grain pattern (u-shaped)
rotary veneer
cut in circular pattern, peeling back layer by layer starting at outside and working way in. creates broad pattern
running match veneer
non-symmetrical matching
rift sliced veneer
cut log in quarters, radial cuts out from center
very linear grain pattern
slip matching veneer
aligned side by side, in sequence to create a repeating grain pattern across a panel
what are 4 characteristics of a T.O.D.?
VARIED HOUSING PRICES
increased bicycle facilites
diverse housing types
mixed-use functions
*decreases parking requirements
what type of soil is preferred for subgrade and foundations?
GW - well graded gravel
where are requirements for # of parking spaces noted?
local municipal code
what does a low emissivity roof do?
holds heat! a high emissivity roof would release it
what is a good way to reduce heat island effect?
incorporate a rooftop garden
what angle should PV arrays be rotated?
ie - building is located 42d north, they should be rotated 42d south
should be south-sloping and tilted at same angle as latitude or greater
where is the maximum bending moment of a balconY?
where it intersects the wall
what will determine the max height of a building?
zoning regulations & FAR
occupancy group - IBC specifies max heights based on this
type of construction - IBC specifies max heights based on this
what is soil liquefaction?
where strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading
what soil is least susceptible to liquefaction during a seismic event?
clay, or clay content of 15% or greater will provide adequate protection from liquefaction
what is the primary function of a vegetated roof?
provide important strategy for managment of stormwater. can reduce runoff on a site by 50%
what are best practices for maintaining defensible space?
- extend defensible space further on the downhill side of a building. fire spreads vertically and travel uphill
- reduce forest density within 100’ from bldng
- store firewood uphill from bldng
- space shrubs at least 10’ apart to protect from spreading fire
- do not use wood chip mulch closer than 30’ to a bldng
what is a DOAS system?
used on projects with high sustainable performance criteria. ability to provide 100% fresh outside air reduces energy dependence
can a septic system increase potential for slope destabilization and landslides?
yes
