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
what is a boundary survey?
shows a property’s boundaries, easements, setbacks, zoning and any improvements such as bldngs, walls, or fencing
what is a topographic survey?
would should spot elevations, and could be at four corners of proeprty
show trees
show utilities
usually done in tandem with a boundary survey
how can you graphically show that a bldng complies with max bldng height requirements?
show dimension of allowable height
show max building envelope
what is primary reason for a FAR?
to control density
what is an example of a type of bldng that has a high building efficiency ratio?
warehouse
has less circulation and support areas
how do you graphically show on dwgs that setbacks are achieved?
need to note property line, setback line, and dimensions from building face
what are reasons you would phase a project?
initial budget is limited
client’s needs are expected to grow
money for project will become available over time
*it is not because of time constraints
what is a zoning variance?
an allowed deviation from zoning regulations
what is an easement?
right to use a portion of land owned by another entity for a specified purpose
what is reconstruction
act or process of depicting, by means of new construction, the form, features, and detailing of a non-surviving site, landscape, building, strucutre etc. for purpose of replicating its appearances (replace in kind)
what is restoration
act or process of accurately depicting the form, features, and character of a property as it appeared at a particular period of time by means of the removal of features from other periods in its history
what is rehabilitation
act or process of making possible a compatible use for a property through repair, alterations, and additions while preserving those portions or featrues which convey its historical, cultural or arch values
what is preservation?
act or process of applying measures necessary to sustain the existing form, integrity, and materials of a historic property
what is 277/480V 3 phase 4 wire appropriate for?
very large buildings, such as multi-story office bldngs or large single story industrial bldngs
what is 120/280V 3 phase, 4 wire appropriate for?
many commercial facilities except large ones
what is 120/240V Single phase, 3 wire appropriate for?
single-family homes or small stores where loads dont exceed 19.2kVA
what is 120/240 V single phase appropriate for?
smallest of bldngs, outbuildings or isolated small loads less than 6kVA
wall schedule
useful for medium-to-large projects
gantt chart
usefull for larger projects
critical path method
useful for larger and complex projects
milestone chart
used for short duration prjects with few tasks and fees under $35K
what percentage would infrastructure use of a residnetial neighborhood’s gross land area?
10-30%
