Introducing Natural Light to ETSU By: Taylor Duncan

Challenge: Introducing Natural Light to ETSU Living and Working Spaces ,[object Object],[object Object],[object Object],[object Object]

Lighting practices in the U.S. have varied widely in the last 70 years ,[object Object],[object Object],[object Object]

A few spaces at ETSU already take advantage of natural light ,[object Object],[object Object],[object Object],[object Object]

Many other spaces at ETSU could benefit from natural light ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Now is a good time to consider increasing use of natural light in ETSU facilities ,[object Object],[object Object],[object Object]

Electricity costs are going up ,[object Object],[object Object],[object Object],[object Object],[object Object]

“ This is going to be the worst year financially (ETSU) has ever seen” -ETSU President, Dr. Paul Stanton ,[object Object],[object Object],[object Object]

ANALYSIS OF THE CHALLENGE “ Energy management is something we can do and are doing.” – President Dr. Paul Stanton

The benefits of natural light have been demonstrated both in terms of energy savings and on how it affects building occupants.

Natural light is being used routinely to save energy in many situations ,[object Object],[object Object],[object Object]

Scientific studies on natural light report positive physiological and psychological impact on building occupants ,[object Object],[object Object],[object Object],[object Object]

Benefits of natural light are reported for the many spaces that make up ETSU ,[object Object],[object Object],[object Object],[object Object],[object Object]

Employees prefer natural light to artificial light ,[object Object],[object Object],[object Object],[object Object]

However, making retroactive modifications to improve natural lighting in existing facilities in challenging ,[object Object],[object Object],[object Object],[object Object],[object Object]

A number of options are available to introduce natural light to ETSU buildings ,[object Object],[object Object],[object Object],[object Object],[object Object]

Pros Vs. Cons Advantages Disadvantages Ability to Retro-fit Skylight ,[object Object],[object Object],[object Object],[object Object],Fairly easy depending on roofing system Atria Bring light to several different floors ,[object Object],[object Object],Extremely difficult, not practical Light-tubes ,[object Object],[object Object],Only effective on top floors Relatively inexpensive & easy to install depending on space Fiber-optics Possible to pipe light anywhere you can place a cable with zero added heat Directional, focused light Expensive Easy to difficult depending on space, place into existing lighting systems

Skylights are low-technology solutions ,[object Object],[object Object]

Light-tubes have three main components to concentrate natural light ,[object Object],[object Object],[object Object],[object Object],[object Object]

Advantages of light-tubes over skylights ,[object Object],[object Object],[object Object],[object Object],[object Object]

Costs of light-tube technology ,[object Object],[object Object],[object Object]

Fiber-optic sunlight concentrators ,[object Object],[object Object],[object Object],[object Object]

Costs of fiber-optic sunlight concentrators ,[object Object]

Disadvantages of natural light technology for ETSU ,[object Object],[object Object],[object Object]

The Center for Physical Activity The workout area The basketball court area

Potential Savings ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Recommendations for introducing natural light to ETSU facilities ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Contact Information ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

I would like to thank all involved in this project for their time, support, and assistance… ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
