Daylighting and Sustainable Lighting are the subjects of this week's blog. Using your text, the library, periodicals and the Internet gather all the info you can find and share on the blog. Remember to find the syllabus for the class in the drop off and on OLS for your reading assignments and the preliminary work for your projects.
Remember also to bring your "Island Getaway" projects to class next week.
Contact me if you have questions: todonnell@aii.edu or 941-321-8447
Please visit the blog several times throughout the week to each other's posts.
Off you go.

Hi everyone-
If anyone could do me a favor that would be great -
I had to miss class wk 2 - I would be really grateful if someone would email me any notes and a list of assignments that are due next week. I checked the syllabus and got some of it, but what is needed as far as preliminary work on the project, etc.

Hi everyone-
I wanted to share this link:
http://www.greenbuilder.com/sourcebook/Lighting.html
It seems to be an excellent detailed yet easy to understand overview. It describes daylighting, how to avoid direct daylighting, and maximize use without heat gain.
There is a whole section that outlines the various sustainable artificial lighting options and how to maximize their use.

Wow! I was shocked at how much thought the light logic exercise required last week but after having read chapters 1, 2 & 7 this week I am absolutely amazed by all of the detail that goes into creating a quality lit environment. The definition of quality lighting being a layered illumination plan that reduces energy costs, conserves natural resources, and allows users of the space to function comfortably, feel safe, and appreciate the aesthetic components of the environment. Lighting seems to be one of those things the average person pays little attention to or gives little credit to. This is unfortunate since poor lighting has such a negative effect on vision, our ability to perform tasks, and our psychological responses.
I found the importance in understanding adaptation and accommodation when designing quality lighting. Adaptation is a function of the eye that adjusts to the amount of brightness entering the pupil and accommodation refers to a function of the eye that enables one to see objects at varying distances. Lighting systems that provide transition and layering of light are extremely relevant considerations to be made in situations where you are dealing with the elderly or in places such as movie theatres where your eyes must adjust from daylight to darkness.
There were also some different types of lighting techniques I learned about and found rather fascinating, one of them being playing with ratios of illumination levels. Apparently extreme drama can be accomplished with a 10:1 ratio but should not exceed 20:1 because the eye may be unable to adjust to the contrast between light and dark. Grazing and backlighting allow you to highlight interesting textures and produce dramatic shadows as well as create the silhouette of an object all by placing the light in a specific direction and angle. It is obvious why all of these techniques are key in dramatic lighting.
Chapter two made the difference between sunlight and daylight very clear. Daylight is desirable natural light whereas sunlight is light from the sun that enters spaces directly. Sunlight is much less desirable due to the fact that it can produce glare and excessive heat as well as fade and damage textiles in an interior. The text described how natural light should be used and depended on as often as possible but for evenings and gloomy days electrical lighting is a must.
Aside from using natural lighting I had no idea lighting played or could play such a huge role in sustainability. There are numerous things to do in lighting to protect the environment. I read that the goals in specifying lighting systems should be to reduce the use of nonrenewable resources, control the use of renewable products, minimize air, water, and soil pollution, protect natural habitats, eliminate toxic substances and reduce light pollution. Simply using energy efficient lights and disposing of used lights in the correct way assist in accomplishing these goals.
I look forward to learning and applying new information about lighting and all it entails in the weeks to come as well as reading my classmates blogs and the information they found. An interesting or perhaps ironic fact to leave off on… as read from the text, The EPA has determined that lighting consumes approximately 20 percent of the electricity used in buildings. In addition, approximately 20 percent of the electricity use for air-conditioning is required as a result of the heat generated by lamps. Hmmm..?

Wonderful points and outline of the chapters Nicole and Wendy, I am glad to see links being posted. Its all about sharing research.
Also, Wendy gets the gold star for first comment.

I found a few good websites to share with you guys. They really gave out great information about sustainable lighting and daylighting. It is nice to have these types of resources at the tip of your fingers and that they are out there for you to consume.

After reading the bit about the Arab World Institute in Paris in the text(pg 28), I thought it sounded pretty interesting and went check it out...turns out it won the Pritzger Prize for architecture this year(2008) - amazing! Here is the link to the Pritzger site and source -

download the photo booklet at the bottom of the page. The interior is amazing!
Another shot that I think really shows the apertures is here:

(scroll down about 2/3 page)
The interior really evokes feeling, texture, and even a historical or futuristic time-through the use of daylight/cast shadow and architectural features. It has a sort of Blade Runner, hazy shadow- play effect.
It so amazing to really see the role that light plays on literally everything!
testing...
if this posts.. can anyone let me know if my other post is visible?
