Sketch Series 3

Fabric Swatch Observations

Space 1: Fluorescent

a. The purpose of Walmart is to serve people as a large chain retail and home goods store.
b. The lighting is ambient lighting that is uniform throughout the space. The purpose of the lighting is to provide lighting throughout the space evenly so that all spaces are accessible, all the products are properly lit, and that all people are able to move throughout the space properly.
c. The lamps are long fluorescent bulbs that are bright and have more of a blue color.
d. The luminaires are long fluorescent fixtures that are placed on a grid system which are also placed close together. There is not one single area throughout the space that is darker than any other.
e. The effect of the lighting source in the space is somewhat loud in both a literal and symbolic way. The lighting promotes high energy and alertness.
f. I feel that the illumination level is a little too high in that it is almost too bright. It has been reported that the illumination levels in stores like this have been raised so that quality of electronics change making more expensive items more appealing.
g. My suggestions would be to either lower the illumination level some or change the ambient lighting to include other forms, such as task and accent lighting. Maybe items would sell better if the lighting was non-uniform, making it more home-like and more imaginable of the customer’s typical living spaces.


Space 2: Halogen

a. The purpose of the space is a kitchen where light is needed under the cabinets to complete tasks.
b. Lighting is needed to use appliances and prepare food.
c. The luminance is a halogen bulb that is very small and unseen but puts off a lot of light.
d. The fixture sits directly under the cabinet and provides down lighting and depending on the quantity the amount of light would change. This source of the light is meant to not be seen.
e. The effect of the light in the space works very well when it is dark in the rest of the space and they are being used for accent lighting or during the day when other lights are on and they are used for completing kitchen tasks.
f. In this particular space the amount of illuminance is appropriate because it does not create a glare on the white counter tops but instead uses them to reflect light into the space. It has never appeared to be a problem.
g. I don’t think that any improvements need to be made on this lighting situation because they have never caused a problem. It depends on the wattage of bulb that we choose to put in the fixture.


Space 3: High-Intensity Discharge

a. The purpose of the space is a parking garage for a university.
b. The purpose of the lighting is to provide light to each of the dark levels of the garage because it is harder for daylight to creep into these spaces. The lighting appeared to be ambient and uniform through out.
c. The lamps appear to be high-intensity discharge lights that are extremely bright when in extreme proximity to them.
d. The fixtures themselves are small square luminaries that put off a large amount of light. The bulb itself is not exposed but with the cover a lot of light is still transmitted.
e. The effect of the light in the space is helpful in that is provides sufficient light to the entire parking deck. There did not appear to be any other areas that were more lit than others.
f. Because the bulbs are high-intensity the illuminance level is high because the bulbs have to work harder to light more area especially when it is dark and there is no other light assisting.
g. My suggestions for the lighting in this space would to have more fixtures because compared to other parking decks they appear to be better lit and have the feel to be safer. Just by observing during the day it did not seem that the number of fixtures would be enough.



Space 4: LED

a. Although not a space, the actual lamp source is a flashlight
b. The purpose of the fixture is a flashlight used in dark situations and space for providing light to function.
c. The lamp is a single LED bulb, approximately the size of the point of a pen that by itself can distract a great amount of light.
d. The luminaire provides direct lighting, allowing the light to only come out of one side. It is powered typically by batteries and is a handheld fixture.
e. The effect of the lighting source is a cone-shaped beam and or a small example of a spotlight. This particular flashlight is highly observed with the blue side of the spectrum.
f. The appropriateness of the lighting fixture is satisfactory but can be difficult when handling by your self. A luminaire this small can only put off so much light so large and detailed tasks are not as desirable with this source in mind.
g. I particularly like sources that are more yellow than blue. I find this LED overpowering and overwhelming. It is almost too blue. My suggestions would be to tone it down some and possible find a way to emit more light than is currently occurring. If this is not obtainable then possibly widen the cone shape beam to provide more light coverage at a closer distance.

Sketch Series 2: Restaurant

Ruby Tuesday

Restaurant

Ruby Tuesday has a lighting design that works well and creates a good mood while experiencing the space and eating a meal. All of the booths on the exterior of the space had a hanging light directly over the table creating down lighting. The shade of the fixture was in a cone shape and looking when up, the bulb of the fixture was exposed. These fixtures were set on a pretty dim setting so that they were not too harsh on the people sitting there. The tables in the middle of the space did not have a light directly over them but had larger lighting in between each of them. They were larger in diameter and they had a semi-opaque cover over them so that the bulb was not directly seen and that some of light was not transmitted through. Windows surround half of the dining space so during the day a good amount of day lighting is coming in. They have the amount controlled by the blinds and the angle at which they are turned. Other more hidden sources of light are provided but sit close to the ceiling and are directed towards objects displayed on the walls.

There appeared to be no noticeable glares yet the place was bright enough but not overly done. All of the lighting sources were either facing in the opposite direction of the view of people or they were dim enough that the placement of them did not really matter. I felt that this place was really thought out and I just had a good feeling while within it. I felt calm and relaxed and the low levels of the lights played a part in noise level of the restaurant. The lights were a warm yellow color instead of on the blue side of the spectrum. This worked well with the warm paint colors that were through out the space.

The lighting in the space in a way directed people through the space because it showed direct placement of the tables and showed people where the clear walkways were. The main dining area is divided down the middle with a wall that is closed on the bottom half but is open on the upper half. This wall is on the end were the windows were not so that the corners with the windows could throw light to its opposite corner through the open space where the wall was open.

[Observations of Space]
-more light appears to be coming in on the right side instead of entering at equal amounts on both sides
-the shadows on the right side are more harsh and defined
-the shadows on the left are softer and seem to fade into the color of the floor
-it is way too hot to sit on the right side (which is where my viewpoint is)
-creates too much of a glare on my paper
-very uncomfortable
-explains why no one was sitting here already
-the area around the windows is way too bright so my eyes had to adjust to looking at the other side of room which is darker because there is no daylight
-approximately two people were sitting on the side with the windows and five people sitting on the side with only electric lights
-after thirty minutes the sun had moved behind my viewpoint and cooled down the space some

Sketch Series 2: Art Gallery

Elliot University Center
Art Gallery

Here when looking at the darker corner of the space the light is way too
bright to even look in that direction.

The small art gallery in the Elliot University Center is a good example of how light has been used in a good and bad way. Providing the most light to the space appears to be halogen floodlights that serve the purpose of highlighting the work that’s on display. Although it does a good job of doing this it also causes a strong glare problem that was not addressed. A supplementary lighting source is the fluorescent light bulbs in the ceiling fixtures. There is one of these located as you first walk in and another one place in the corner where the room changes direction.

The problem with the halogen lights is the direction in which they are giving off light. They are pointed to face the opposite wall than what one would think. I understand why one would think this would work because it changes the distance of the lighting source, which in turn provides light to more space. I think by having them the way they are now prevents them from creating glares on the walls. The walls appear to be a white matte paint finish, somewhat textured. If the lights were to be turned around I think they would be too close to the wall and at that point create unnecessary glares on the walls preventing the artwork from being enjoyed. The problem that is present with this overall lighting design is that the halogen lights, although they provide sufficient light to the artwork, they do not allow the users to enjoy the space the best they could. I found myself squinting to work my way around the space. Everywhere you looked there was some kind of light that was blinding you. I find this a real big problem.

While I was there observing the space there were no other viewers. Naturally I started moving through the space by starting on the right and working my way around the perimeter. This most likely would be the way that people inhabit the space because there is one entrance so you enter, observe the art while working your way around the perimeter, and then exit the same door in which you entered. So based on this situation the lighting needs to be in favor of this. The lights don’t need to be facing the viewers at any point while they are enjoying the space because this could cause them to have a bad experience.

[Uses of Space]
-community study space
-waiting area for elevators
-traffic area for people going to find books

[Furniture]
-3 sets of tables and chairs
-2 booths
-chairs and table under windows

[Shadows]
-light comes in from both sides of the space creating shadows from either side
-more defined shadows on the left side of the space than the right where there is only electric
lighting
-table tops next to windows have strong reflections

[Feeling of Space]
-more pleasant on the left side because of the daylighting than on the right
-this feeling would change once the sun would set

-approximately the same amount of people were sitting on the left with the sun as were
sitting on the right with the electric lighting

[Lighting Fixtures]
-mounted to the ceiling
-uniform lighting
-appear to be place evenly throughout the space
-not placed based on the furniture or task oriented

[Weather Conditions]
-cloudy overcast
-no visibility of the sun

The student lounge of the Gatewood building is a space equipped with tables and chairs, primarily used by students needing a quiet place to study. It is adjacent to the vending area, as well as lockers for art students. The lighting in the space is comprised entirely of electrical track/suspended florescent and flood lights, with no access to windows. We rated the space halfway between public and private, as the actual study space is rather small and is only ever used by a few students at a time, but also serves as a pathway to lockers and vending.
Students trying to study will be easily distracted by constant circulation of people. Overall, we do not feel the space is designed well for what it is meant to be used for. The space feels cold (as there are no windows), and is not a very pleasant work environment.

Lighting and Health

Lighting and health have a strong correlation and multiple research studies have been conducted to explain the relationship between the two. In my preparation in becoming a designer until this point I was never aware that first of all light is an extremely important aspect of design, and secondly that the decisions that designers make about lighting can effect the health of the people inhabiting the spaces.

Instinctively we know that light at night can effect our sleeping patterns but the major health risks also involved is something that I find useful and very informative when it comes to designing spaces. Having a light on at night is going to prevent us from having an efficient amount of sleep for our body to function properly. Personally I know how having the lights on or off affects me. I am more likely to fall asleep in class if a teacher is to turn the lights off to show a movie. Also a saying that we have all heard growing up and that I remember my dad telling me is that watching television in the dark is bad for your eyes. Another assumption that we all have is that we must have enough lights to complete the tasks that we are working on, but in truth most of us have too many lights on and it is more healthy to have fewer lights or just the right amount of daylight.

The most astonishing fact from the article Influence of Architectural Lighting on Health, by Eve Edelstein, and from the article Lights at Night Are Linked to Breast Cancer, by Rick Weiss, is the connection of lights at night and breast cancer, as stated in the second title. This is a fact that not everyone knows about but is one that the people deserve to be informed about. Also as the designer it is our job in the future to find a solution that fixes this problem. It is stated in the articles that people who are exposed to too much light during the nighttime hours are more likely to be diagnosed with breast cancer. An experiment was completed and concluded that locations with higher amounts of light at night are thirty-seven percent more likely to have a higher cancer rate than locations with the lowest amount of light at night. Currently these lighting situations are only partial in the production of breast cancer, not any other form of cancer. When I first read this information I started wondering if these locations with higher amounts of light would be large cities and if smaller towns would fall under the category of the lowest amount of light at night. Does this mean that since I am from a small town hidden in the valley of the Blue Ridge Mountains that I have a less likely change of having breast cancer? Has living in Greensboro upped my chances of receiving cancer? Do smaller towns hidden in the mountains have an advantage over the small towns out west?

In Rick Weiss’ article he states that there is a hormone called melatonin that our brain forms to prevent tumors from forming. This hormone is produce mostly at night and so the presence of light causes the levels to drop drastically eventually causing the body to develop cancer. A discovery that has been made states that the energy efficient fluorescent bulbs that energy professionals recently informed people to gradually start switching to has been confirmed as a light that hinders the melatonin hormone from forming. In fact the incandescent bulbs that are slowly going out of style have been proven to hinder the production of the melatonin hormone less than the fluorescent bulbs. I find this interesting because the people as a whole are going to have to choose between their personal health and being energy efficient.

Something interesting that stood out to me in the article The Claim: Daylight Saving Time Can Affect Your Health, by Anahad O’Connor, was that a claim was made that Daylight Savings Time will disconnect a person’s body time from the actual clock’s time which, can lead to greater intense health problems such as heart attacks and suicides, and the most common result, sleep disruption. As a first thought I was not convinced that a one-hour time difference would cause such great health problems, but then came to the conclusion that this constant change could eventually lead to the sleep problems, which could later develop into greater health risks.

The connection and direct correlation between light and health was new information to me, something that I am now appreciative of knowing.
