Blog: Lighting calculations and research on the various types lighting certification (web searches, periodicals and library searches).
For Week 10:
Bring everything you need to class for working on your projects. I want to spend time with each of you individually.
If you need computers and don't have a laptop. We'll spread around the building as needed.
I also arranged for Drew to make the AutoCAD program work in our classroom, so that terminal is available as well.
Other than work on a simple lighting calculation, this will be a studio day. The culmination of all three of your projects will be due at the top of class on Week 11:
Projects I, II and III• Burn copies of your assignments to CD for me to keep (scan non-digital work)
• Turn in hard copies of your assignments on 11” x 17” paper (DO NOT STAPLE). Copies only as these will go into permanent files and will not be returned to you.
Off you go!

I did that (above entry) wrong...how do i delete it?
I deleted it for you.
From what I have read about Lighting Certifications, I've gotten that there are several different certifications that you can obtain. I believe that an AEE certification is one of the most prominent certifications, or one of the most recognized. The AEE enables professionals to receive special recognition for their expertise in a variety of specialized areas of the energy industry. The different certifications include a CBCP, CEP, CMVP, CPQ, CSDP, DGCP, and a GBE. What specifically each of these certifications include, I couldn't tell you, but they all pertain to the standard of lighting that is used and the sustainable value of the lights used.

I found a great site for lighting calculations that include how many fixtures that are required for a room which also includes how far the light will spread to a work area and takes into account different factors of the room.

I couldn’t find much on lighting certifications. I had attempted to visit the site that Kristen had posted, but was unable to open it. However I did find some other organizations like the Illuminating Engineering Society of North America (IESNA) that combined with organizations like ANSI and ASHRAE that has guidelines, standards and a handbook that categorizes lighting based on different environments. The International Association of Lighting Designers (IALD) is an organization which focuses on the advancement of lighting design education and the recognition of independent professional lighting designers. The National Council on Qualifications for the Lighting Professions (NCQLP) offers the Lighting Certification Examination which tests rudimentary lighting design principles. Individuals who pass this exam become Lighting Certified and may append the abbreviation LC to their name. This certification process is the only national examination in the lighting industry and is open not only to designers, but to lighting equipment manufacturers, electric utility employees, etc.
I found an interesting article on
http://findarticles.com/p/articles/mi_qa3922/is_200003/ai_n8886374
The title of the article is “New Lighting Certification Targets Energy Efficiency”, it states that there is a new certification program for energy efficient lighting service companies seeks to improve and increase the knowledge and capabilities of participating lighting service companies. The program is called Certified Energy Efficient Lighting Service Company (CEELSCo), and is developed by the (EELA) Energy Efficient Lighting Association. The program will identify those companies accredited as upholding the technical and ethical standards of EELA. This type of certification benefits the industry by increasing the overall awareness level of the marketplace and enduser confidence.
I think that this type of certification is very important and useful for the lighting industry. If more companies become more aware of the CEELSCo, many of them would want to become certified, knowing that they are doing good for the environment. Since many of us are working towards sustainable design, it is a good thing that in the lighting industry you can actually get certified for it.
Halle and Kristen both did a great job at detailing information about the many lighting certifications out there to obtain, so I wanted to share some information that I found about lighting calculations.
I found this site which detailed a common method and lighting formula.
http://www.ndlight.com.au/lighting_calculations.htm
The site broke down the process into five steps:
Step1: understanding the fittings and how they will light the space. All fittings (luminaries) come with illumination factors, as a designer one must understand what these ratings/factors mean.
Step2: Calculate the Room Index. The room index is a number that describes the ratios of the rooms length, width and height.
The room index can be found by applying this formula:
K = L x W / Hm (L+W)
These are the abbreviation meanings:
L = Room Length
W = Room Width
Hm = Mounting Height of Fitting (from working plane)
Work Plane = Desk or Bench Height
Typically this result will range between 0.75 and 5
Step 3: This is where things get a bit tricky. Now using the Room Index value (K) and the reflectance value one can apply the data to the table which is found on the site.
Step 4: This is the step in which a designer can determine the needed number of fittings for the space by using the following formula:
N = E x A/F x uF x LLF
When:
N = Number of Fittings
E = Lux Level Required on Working Plane
A = Area of Room (L x W)
F = Total Flux (Lumens) from all the Lamps in one Fitting
UF = Utilisation Factor from the Table for the Fitting to be Used
LLF = Light Loss Factor. This takes account of the depreciation over time of lamp output and dirt accumulation on the fitting and walls of the building
Step 5: Next a designer should space the fittings out uniformly around the room, paying special attention to areas that are task oriented.
This site was a bit confusing and might have given too much information, but I think it is good to search for different sources along with our text. The more you can attempt to understand the better. Hope it helps.
I think it is great there is a certification for lighting this helps to raise the professional standards of lighting and to improve the quality of lighting. In order to get certified a person must complete a application process that is based on education and experience in lighting. The applicant receives points based on this criteria and must have a certain number of points in order to be legible to take the four hour written exam. Once the person passes the exam and becomes a LC they must have continuing education to keep up license. The CELP (CERTIFICATION PROGRAM FOR
CERTIFIED LIGHTING EFFICIENCY PROFESSIONAL) and the NCQLP (The National Council on Qualifications for the Lighting Professions) are two organizations that a person can get a certification.

This site offeres informatin about after recieving a ligthing certification from NCQLP. It tells about renewal and lighting education units (continuing education).

This web site offers a different type of lighting calculation. The first part will help in calculating lamp burn time. The second chart (which is to be used in excel) helps to automate the comparing of two lamps; it helps in determining which is more economical in the long run.
Careers in Lighting
In the building and construction industry
Lighting is an exciting and challenging field. Because it is both an art and a science, the field attracts men and women who love diversity and enjoy the opportunity to be creative in what they do.
An increasing number of people are entering the field with an educational background in lighting, but the majority of today's lighting professionals are still prepared in other educational settings or through experience. Regardless of whether your interests are design, manufacturing, sales or business, lighting offers a wide range of job opportunities, especially if you like to work with something that is practical and serves all of us in many ways - LIGHT!
The different certifications include a CBCP, CEP, CMVP, CPQ, CSDP, DGCP, and a GBE. AEE certification is one of the most prominent certifications, or one of the most recognized. The AEE enables professionals to receive special recognition for their expertise in a variety of specialized areas of the energy industry.
Lighting Certification by the NCQLP is an important step in a successful lighting career. Becoming Lighting Certified (LC) means you have not only opened the possibilities for many of the career paths in the world of lighting but have also made a commitment to lighting as a profession. The LC credential demonstrates a basic but broad knowledge of lighting and that you understand the importance of lighting quality and effectiveness
