Arch 273 Final Exam

Terms in this set (29)

Embodied Carbon
The total carbon emissions associated with a material or product throughout its life cycle. The carbon footprint
Life Cycle Assessment (LCA)
cradle-to-grave or cradle-to-cradle analysis technique to assess environmental impacts associated with all the stages of a product's life, which is from raw material extraction through materials processing, manufacture, distribution, and use.
Cradle to gate
Planning sustainability from the procurement of raw materials through the production of the product.
Cradle to grave
Planning sustainability from the procurement of raw materials through the final disposal of the product.
Architecture 2030 Challenge
calls for all new buildings, developments, and major renovations to be carbon-neutral by 2030
globally reduce fossil fuel consumption and advance development of sustainable cities
2 Goals of 2030 challenge
Revit plug in and stand alone
Tools to estimate carbon impacts of a building
Tally life cycle assessment
Example of Revit plug in tool
Athena sustainable materials institute
Example of stand-alone tool
Embodied Carbon and Construction Calculator (EC3)
What tool is used to compare different options at the product scale?
Sound
energy that can be heard
Vibration
energy that can be felt
20-20000 hertz
Typical frequency detected by the human ear
Noise
unwanted sound
Octave Bands
a range or span of frequencies identified and named by a center frequency
Octave band uses
Information about sound characteristics (such as power level) at several (perhaps 4, or 6, or 8) octave bands is generally used to describe architectural sounds
reflected, absorbed, transmitted
Three ways sound can interact with space
100% of the sound energy
The sum of reflectance, absorption, and transmission will always be:
echo, creep, focusing, flutter, distortion
Types of sound anomalies
echo
reflection (repetition) of a sound event (a footstep, a syllable, a word, a hand clap) that is sensed as being temporally separate from the original sound signal
creep
Caused by curvilinear (or faceted planar) focusing geometry and hard surfaces
Distortion
rebalancing of sound frequencies in the reverberant field (following one or more reflections)
NRC
measurement of how well a product makes the room you are in quieter
STC
measures how well a product keeps sound from escaping the room.
Noise Reduction Coefficient
NRC
Sound transmission class
STC
large gymnasium to make room less noisy
Example of NRC encounter
office space to make room more soundproof
Example of STC encounter
There is no acoustic comfort zone
