Flashcards in Comfort Concept Deck (90)
How many features are there?
4 areas of comfort
Study of sound and properties of a space or building that determine how sound is transmitted or reflected within it or though it.
Energy composed of pressure waves, or vibrations, that travel through the air or another material and produce an audible signal when they reach person’s ear
Can be measured in Hertz Hz
Unit of measure used for frequency that a wave cycles, or repeats, its wavelength
Equal to one cycle per second
What frequencies can human ear hear?
20Hz to 20,000 Hz
Can cause physical, psychological stress leading to cardiovascular stress, decreased productivity, and cognitive performance
Adapting objects, spaces, such as workstations and workflow
Injury affecting body’s movements or its muscles, bones, tendons, nerves, or ligaments
Refers to sense of smell, perception of air quality, unpleasant smell causes stress
Follows standard ASHRAE Standard 55-2013, Thermal Environmental Conditions for Human Occupancy
Rate of transformation of chemical energy into heat and mechanical work by metabolic activities of a person, expressed in units of met
Resistance to sensible heat transfer provided provided by a clothing, expressed in units of clo
Temperature of air surrounding an occupant taken with a dry bulb thermometer, measurede in C or F
Average of surface temp of the surroundings which body can exchange heat by radiant transfer, measured in C and F
Mean radian temperature
Rate of air movement at a point without regard to direction, measured in m/s (fpm)
Average moisture in air, measured in percent of releative humidity %rh
Math and graphical study of the properties of air
Graphical representation of properties of air
Determine comfort zone
