Instructor
Richard G. Mistrick, Ph.D., P.E.
Associate Professor of Architectural Engineering
223 Engineering A

Office Hours: MWF 2:00-3:00, TR 11:15-12:05 or by appointment

Course Objective
To study lighting design and analysis theory and to cultivate an understanding of good lighting design practice through a series of design and analysis problems. Topics addressed include design criteria, design practice, hardware and analysis procedures for outdoor area lighting, economic analysis of lighting systems, interior lighting design, daylighting and lighting system visualization. Commercially available computer software will be utilized.

Meeting Time
MW 9:05 am - 11:00 am, F 9:05 - 9:55 am.

Course Format
This course will include a combination of lectures, classroom discussion, case studies and projects in a Computer aided lighting design studio. Final project presentations will be presented in Powerpoint and/or submitted in report format. Practicing professionals, faculty, and classmates will be invited to critique student work. These critiques are intended to provide an enhanced learning experience for all students through the evaluation of others work and throughcontact with design professionals.

Assignments
Seven projects will be performed. Each will require a project report and/or presentation which includes detailed information on the design criteria, equipment selection, system layout and a study and evaluation of system performance.

Grading
Each project will be worth between 10 and 20% of the course grade.

Deadlines/Late Penalty
Project deadlines will be strictly observed. A deduction of 10% will be applied to each 48 hour period that a project is late, unless an extension is granted prior to the project deadline for a valid excuse.

Attendance
Attendance is required and critical to the learning process. All students are expected to be in attendance during regular class meeting times. Two unexcused absences are permitted during the semester (see attached). Additional absences may result in lowering of project grades.

Obtaining Photometric Files [TOP]

Photometric Files are available on the L Drive in the \PHOTO directory for a large number of manufacturers. Most manufacturers provide some type of index for their photometric files. Look for this index using the File Manager and view it to locate the file name for the luminaire that you plan to use. If you have a catalog number or other information, you may want to search all files within a directory for a particular string of characters (a portion of the catalog number or a known candela value).

A number of manufacturers's data can be obtained from software programs that have photometric databases, which are available in the CAD Lab. These are listed below (click on the program name to obtain instructions for creating IES files using these programs:

Lite*Pro - Columbia, Prescolite, Moldcast
Lumen-Micro - Assorted Manufacturers
Luxicon - Cooper Lighting Products

Reflectances of Materials in Radiance

The general formula for the reflectance of a plastic surface is:

= (.263 * R + .655 * G + .082 * B) *(1-S) + S

R, G, and B are the red, green and blue values and S is the specularity (fourth parameter).

A 75% reflectance gray diffuse surface is simply .75 .75 .75 0 0.

For metal, the reflectance is equal to:

= (.263 * R + .655 * G + .082 * B)
