Introduction
thesis statement
states position
Building design
need
to improve the
design of daylighting
in order to create a more beneficial environment for users.
what does a more beneficial environment consist of?
without access to windows, views, and daylighting in our schools and workplaces, people's health and well being suffer.
daylighting is good for many reasons
environmental and energy saving
assume they know the very basics but not much more
conclusion
the problem
the buildings we work in do not have adequate sunlight for optimal benefits
example: robert bell
past buildings had to rely on daylighting
"In the early part of the 20th century, natural light was the primary source of building illumination. In a short span of a couple of decades, electric lighting sources became the primary source of illumination because of convenience mostly" (Shishegar 151).
example: noyer + stu
with sunlight and how to incorporate it
more daylighting in buildings, especially work environments and schools
most of our time is spent in work environments and classrooms
we are using computers and other sources of artificial light in these environments, so it is important to offset the effect
allows us to control our circadian rhythm during the day so we will get better sleep at night
"Many individuals spend most of their days indoors at work with limited exposure to sunlight" (Fitzgerald 771).
"Students in the green window view condition scored significantly higher on tests of attentional functioning and recovered significantly faster from a stressful experience than their peers who were assigned to rooms without views to green spaces" (Sullivan 153).
optimal daylighting for optimal benefits
what does optimal daylighting consist of?
ammount
color
pleasant views from windows
what makes up a pleasant view?
nature and greenery
not the backs of buildings and alleys
sunlight
window size
what does improving daylighting actually mean?
the causes of the problems
lack of windows in work spaces to provide light
entry areas of buildings will have large windows but classrooms or offices have few or none
for example, the letterman building
daylighting vs. electric lighting
health
vitamin D
"about 42% of the US population is vitamin D deficient with some populations having even higher levels of deficiency" (Wheeler).
Impacts on healthcare environments
pain
"Pain levels will be perceived as lower in rooms with more daylight and better window views" (Shepley 54).
mood in ICU units
"The physical environment has been found to have a significant impact on patient, family, and staff outcomes in healthcare setting" (Shepley 46).
circadian rhythm
natural vs artificial light
we see more artificial light and it affects our minds/sleep
full spectrum vs. blue light
causes visual fatigue
staying awake during the day
"in the course of the afternoon, subjects felt sleepy earlier under [electric lighting] than [daylighting]" (Borisuit 203).
getting to sleep at night
issues caused by lack of sleep
the use of sleep aids
melatonin to replace the natural buildup of the chemical
sedatives
mood + focus
stress
stuff from the ICU quotes above
productivity
adequate amounts of sunlight may improve productivity as well as overall health (Fitzgerald 770).
seasonal depression (SAD)
"The reduced level of sunlight in fall and winter may cause winter-onset SAD. This decrease in sunlight may disrupt your body's internal clock and lead to feelings of depression Melatonin levels. The change in season can disrupt the balance of the body's level of melatonin, which plays a role in sleep patterns and mood" (Seasonal).
"Seasonal affective disorder (SAD) is a type of depression that's related to changes in seasons — SAD begins and ends at about the same times every year. If you're like most people with SAD, your symptoms start in the fall and continue into the winter months, sapping your energy and making you feel moody" (Seasonal).
list symptoms
counter claim???
full spectrum light bulbs
vitamin D supliments
Melatonin and other sleep helping medications
you can't use daylighting at night
survey stuff?
how much time do you spend outdoors on a given day?
How many of your classrooms have windows?
How long do people use computers and technology on a given day?
If given the choice, would you choose a room with windows vs. no windows?
do you prefer natural or artificial light when working and studying?
Do you experience any sleep problems?
do you use sleep aids?
do you experience any of the symptoms of SAD?
how much time do you spend working inside a classroom or workplace?
