WELL AP – Light UPDATED Exam
Questions and CORRECT Answers
WELL Light - CORRECT ANSWER - This concept promotes exposure to light and aims
to create lighting environments that promote visual, mental and biological health
- aims to provide a lighting environment that reduces circadian phase disruption, improves sleep
quality and positively impacts mood and productivity
Light - CORRECT ANSWER - is the main driver of the visual and circadian systems
- is the main driver of the circadian system, which controls body processes, such as digestion,
the
release of certain hormones, body temperature and sleep
diurnal - CORRECT ANSWER - innately prone to wakefulness during the day and
sleepiness at night.
- humans
Light exposure - CORRECT ANSWER - Stimulates the circadian system, which starts in
the brain and regulates physiological rhythms throughout the body's tissues and organs, such as
hormone levels and the sleep-wake cycle
- has an impact on the mood and reduces symptoms of depression in individuals
- can affect how we recover and heal
- linked to increases in productivity and
sleep quality, as well as reduction in symptoms of depression in individuals.
The circadian rhythm - CORRECT ANSWER - is synchronized with the natural day-night
cycle through different environmental cues, the main cue being light
- 24-hour cycle internal clocks in humans and animals
,Desynchronization of the circadian rhythm - CORRECT ANSWER A. has been linked
with:
- obesity, diabetes
- depression
- metabolic disorders
B. Caused by exposure to bright light at night
C. Can cause breast cancer and metabolic and sleep disorders.
circadian photoentrainment - CORRECT ANSWER All light—not just sunlight—can
contribute to
phase advance - CORRECT ANSWER exposure in the late night/early morning will shift
our rhythms forward
phase delay - CORRECT ANSWER exposure in the late afternoon/early night will shift
our rhythms back
- onset of depression
- impairment of cognitive function in individuals. - CORRECT ANSWER Reduced
exposure to daylight has been linked to the:
L01 Light Exposure (P) Intent - CORRECT ANSWER Provide indoor light exposure
through daylight and electric light strategies
L01 Light Exposure Summary - CORRECT ANSWER This WELL feature requires
projects to provide appropriate light exposure in indoor environments through lighting strategies.
L01 Light Exposure Issue - CORRECT ANSWER - The increase in the use of electric
lighting has led to indoor environments relying on electric light over daylight.
- Reduced exposure to light has been linked to the onset of depression and impairment of
cognitive function in individuals
, Irregular sleep-wake cycles - CORRECT ANSWER have been linked to poorer academic
performance in college students
200 years. - CORRECT ANSWER Electric light has only been widely used as a source of
light for less than ____ years.
L01 Light Exposure Solution - CORRECT ANSWER Providing indoor access to adequate
light can positively influence the productivity and mood of individuals,
while supporting the alignment of their circadian rhythms with the natural day-night cycle.
indoor lighting - CORRECT ANSWER achieved through building design, façade design,
space layout and lighting design.
Windows, atriums and skylights - CORRECT ANSWER are design features that can be
utilized to increase daylight in a space.
L1 Part 1 Opt 1: Daylight Simulation (For all spaces EXCEPT Dwelling Units) - CORRECT
ANSWER Regularly occupied spaces achieve one of the following:
A. Average sDA 200,40% is achieved for > 30% of regularly occupied floor area OR Target
illuminance 19 fc(200 lux) is achieved for >30% of individual unit area throughout 50% of daylit
hours of the year
B. Average sDA 300,50% is achieved for > 75% of floor area OR Target illuminance 28 fc(300
lux) is achieved for >30% of individual unit area and average illuminance 9 fc(100 lux) is
achieved for >95% of individual unit area throughout 50% of daylit hours of the year
sDA (Spatial Daylight Autonomy) - CORRECT ANSWER a unit that indicates the % of
floor space, where a minimum light level can be met completely for some proportion of regular
operating hours by natural light
