6 Flashcards
According to the Centers for Disease Control (CDC), how is “fitness” defined?
Fitness is defined as the ability to carry out daily tasks with vigor and alertness, without undue fatigue, and with ample energy to enjoy leisure time pursuits and respond to emergencies.
How much activity should a healthy adult engage in per week?
Per the American College of Sports Medicine, a healthy adult should engage in at least 30 minutes of moderate intensity aerobic activity five days per week, muscle strengthening activities at least two days per week.
What is one of the biggest modern threats to public health?
Physical inactivity. Lack of physical activity can increase the odds of a stroke by 20-30% and shave off 3-5 years of life. It is the fourth leading risk factor for mortality, accounting for 6-9% of deaths worldwide.
Stair climbing has been associated with which health benefits?
Improved respiratory fitness and a lower risk of stroke
To promote the use of stairs within a building that is at least 2 floors, what is one requirement to meet the WELL standard prerequisite?
Stairs are required to be located within 25 feet of the entrance to the building or the edge of its lobby
To make both stairs and paths more aesthetically pleasing, what are items that can be incorporated to improve the appeal?
Artwork, music, daylighting using windows or skylights, windows to the outdoors or the interior, light levels of at least 215 lux when stairs are in use.
How much moderate intensity physical activity is needed to reduce an overall mortality rate by 20%?
Only 2.5 hours per week are needed to reduce mortality rate by 20%
To encourage neighborhood connectivity and daily activity, what is one requirement that should be met?
The building has a walk score of 70 or better
What are two methods that are considered active transportation?
Biking or walking. Both of these methods have been associated with lower rates of diabetes, hypertension, overweight and obesity
According to employee surveys, what problem is the leading source of dissatisfaction within the environmental conditions of an office?
Acoustic Problems
In addition to acoustic comfort, what other two items play a significant role in mitigating physical and mental stress?
Along with acoustic comfort, ergonomics and universal design play a significant role in mitigating physical and mental stress.
In what systems of the human body are most of the adverse effects of ergonomics?
Most adverse health effects are found in musculoskeletal and nervous systems of the body. Musculoskeletal disorders (MSDs) include low back pain, neck pain and osteoarthritis.
What are the 6 primary personal and environmental variables that contribute to an occupants thermal comfort?
Air speed, dry build temperature, radiant temperature, humidity, metabolic rate and clothing or other insulation.
What is a requirement of visual ergonomics within an office?
All computer screens must be adjustable in terms of height and distance from the user.
Studies show that individuals that are exposed to traffic noise or any loud, repetitive exterior noises, can have a higher risk for which health concerns?
Higher risk for diabetes, stroke and heart attack. Those exposed to road traffic and aircraft noises have a higher risk for hypertension.
In regards to sound pressure level, each regularly occupied space must meet what sound pressure level when the space and adjacent spaces are unoccupied, but within 1 hour of normal business hours?
The occupied space must not exceed 50dBA form outside noise intrusion
What is the reason for the feature “Exterior Noise Intrusion”?
Exterior noise intrusion sets indoor level limits for noises originating outside of the building. These limits help to ensure that the exterior noise does not distract building occupants.
An acoustic plan is developed to identify what spaces inside a building?
An acoustic plan is developed to identify loud and quiet zones and noisy equipment in the space
How is thermal comfort within the body provided?
Thermal comfort within the body is provided through homeothermy, which is the balancing of heat gains and losses to maintain the body’s core temperature within its narrow range, 97-100 degrees.
According to ASHRAE Standard 55, what are two ways in which thermal comfort can be achieved?
ASHRAE 55 specifies that thermal comfort can be achieved either through the Standard Comfort Zone or the Adaptive Comfort Zone.
All spaces in mechanically ventilated projects must met what criteria?
These spaces must meet the design, operating and performance criteria of ASHRAE 55-2013 Section 5.3, Standard Comfort Zone Compliance.
All spaces in naturally ventilated projects must meet what criteria?
These spaces must meet the criteria according to ASHRAE 55-2013 Section 5.4, Adaptive Comfort Model.
