Name 5 main purposes of interior finish.
|
Neat and tidy look. Resist wear and tear.
Control sound. Control fire. Conceal bldg services. |
|
Name 4 criteria for selecting interior finishes.
|
Appearance, Durability/maintenance
Fire, Changeability Cost, Indoor air quality (IAQ) Acoustics |
|
Both the comfort level and the marketability can be affected by the choice of _______________ of the interior finish.
|
appearance
|
|
For a durable interior, name 3 uses that may require special needs.
|
1. Intensity of use (like airport corridor)
2. Water resistance (kitchen/bathroom) 3. Cleanliness and maintenance needs (hospital vs office) |
|
Acoustical ceiling, carpeting, and lightweight partitions are examples of interior finish selections that are easily _________________.
|
changeable
|
|
What is included in life cycle cost?
|
Initial cost (purchase and installation) +
maintenance + replacement + energy costs |
|
Rather than simply focusing on initial cost, a more holistic approach is "life cycle cost" which includes first, _________________, replacement and energy costs.
|
maintenance
|
|
As a general rule, interior finishes that offer high durability are more expensive than less durable alternatives.
TRUE FALSE |
TRUE
|
|
The interior construction elements that prevent smoke and fire from traveling between spaces within a building via the HVAC ductwork are called ______________________.
Smoke chalking, fire safing, fire dampers, all ,none |
fire dampers
|
|
Office and retail spaces tend to feature heavier, more durable finishes than typically used in specialty interiors found in civic buildings such as performing arts theaters.
TRUE FALSE |
FALSE
|
|
Distance to make one cycle is _____________.
Loudness, height of wave, is ____________. Number of times a wavelength occurs in one second is the _________ or ___________. |
wavelength
amplitude frequency, pitch |
|
Soft, porous finsihes tend to _________ sound whereas dense, hard materials tend to ___________.
|
absorb
reflect |
|
________________ ____________ is a measurement of white noise, which can increase the level of speech ____________.
|
Noise criteria
privacy |
|
Name 3 ways to reduce sound transmission through floors.
|
1. Cement/gypsum self-leveling floor covering (liq). Fills holes & cracks to increase soundproofing.
2. Cushion the floor to control impact noise. 3. Float the floor to control impact noise. |
|
Name 3 ways to reduce sound transmission through walls.
|
1. Resilient mounting - dry wall attached to thin metal strip out from studs.
2. Staggered studs. 3. Double wall - small gap between studs. 4. Avoid back-to-back receptacles. 5. Install sound barrier in plenum space above partition walls. |
|
A standard rating of a barrier's resistance to sound transmission as a function of frequency is ____________ __________ ___________.
|
sound transmission class (STC)
|
|
Vertical runs for MEP are called ______, ______, or ________.
What services are inside them? Why are they sealed? |
shafts, risers, chases
Wiring, ducts, plumbing To prevent spread of fire & smoke |
|
For horizontal distribution of MEP services, ____________
are used to suspend piping, ducts, wiring, etc in the plenum space. Another way to suspend cables is by ___________ _________. |
struts (unistrut, wire hangers)
cable trays |
|
_______________ is the number of pressure difference cycles that occur within one second.
Decibels, frequency amplitude, wavelength |
Frequency
|
|
The ideal combination of material types for creating quality of listening conditions are:
Absorber only Reflector only Absorber over reflector REflector over absorber |
Absorber over reflector
|
|
The measurement of white noise within a space is called "Noise __________".
|
Criteria
|
|
One solution to reducing the transmission of sound through a floor is to "float the floor", which entails specifying a soft, resilient floor finish such as plush carpeting.
TRUE FALSE |
FALSE
|
