FEMP Lights I: Issues

Syllabus 

Section -  I-1 |  I-2 | I-3 |

The Course Focus:

The course focuses on managing lighting efficiency retrofits for the workplace. It is designed for building or facility Energy Managers, or anyone who wants to get up-to-speed and up-to-date on lighting efficiency for the workplace. The class addresses workplace lighting, including offices, institutional, industrial and warehouse spaces. The class does not cover special issues for outdoor lighting, retail or residential lighting. The course complements other FEMP workshops by stressing the integration of efficient lighting with whole building energy analysis and life cycle cost analysis. Release of course materials is timed so that students must complete the quiz for the section to gain access to the next course lessons

Objectives: Before the course has officially begins for the term, the students will have establish an Internet account, and work out any bugs with viewing the PowerPoint files. They are also given an overview of the goals of the course.

Section I-1

I-1.1 - Why This Class?
Objective: The students will be familiarized with the rationale behind Federal energy efficiency initiatives and what resources the government has made available to realize these initiatives. The course will discuss the impact lighting has on the work environment (productivity) and the global environment (emissions from electricity production).
Supplemental Activities: The students must find out how EPAct 2005 will impact their workplace and what energy reduction goals does their Agency have.
Reading: I-11why.ppt.
Optional: Place an order for the text of EPAct 2005 and Executive Order 13123. Find the Internet sites with information on Global Climate Change.

I-1.2 - Overview of Lighting Energy Use
Objective: This lesson will describe the energy consumption and costs associated with electric lighting. Interaction effects between lighting usage and HVAC operation will be presented as well as the demand and energy components of electricity costs. By the end of the lesson the students should have a rough estimate of the costs of operating the lights in their buildings.
Optional Activities: Find out what the electricity rates are for their site (usage, demand and average costs).
Reading: I-12energy.ppt.

I-1.3 - A Brief History of Lighting in the Workplace
Objective: This lesson describes the evolution of lighting from the use of daylight, to gas lamps, to incandescents up to modern fluorescent technology used in most offices today. These descriptions are accompanied by supporting photographs so the various lighting systems are quickly recognizable. By the end of the course, the students will be able to recognize the age of the lighting system by the types of components used.
Optional Activities: Find out the most antiquated and modern lighting systems at your sites.
Reading: I-13history.ppt

I-1.4 - An Overview of the Retrofit Process
Objective: The students will learn the 5 steps to a successful lighting retrofit: 1)Screen - quickly prioritize which projects have the greatest potential, 2)Select - collect detailed information on the top projects, 3)Design - evaluate different design options, 4)Implement - purchase the proper materials and services, 5)Evaluate - learn from your successes and mistakes. Examples are given on different loads of effort for lighting retrofit.
Optional Activities: Observe & report on a lighting retrofit.
Reading: I-14retro.ppt.

Section I-2

I-2.1 - Vocabulary: Talking About Light
Objective: The students will learn the basic vocabulary of light. In addition to description of illuminance, luminous flux, luminance and luminous intensity, typical values of each of the units are given. Efficiency and efficacy will be differentiated.
Optional Activities: Vocabulary questions based upon the lesson and reading.
Reading: I-21vocab.ppt.

I-2.2 - Vision and Perception
Objective: This lesson will describe how the humans process visual information; adaptation, aging, glare and color vision will be discussed. Students will discover that contrast can be positive (highlighting and sparkle) as well as negative (glare and poor visibility) and how to strike a good balance depending upon the circumstances.
Optional Activities: Describe examples of glare and other lighting effects in the workplace.
Reading: I-22vision.ppt.

I-2.3 - Color Vision and Perception
Objective: The students will learn that perceived color is the result of the interaction of the source illuminant, the color of surface pigments and the physiological accommodation of the viewer. The students will learn develop the color terminology for light sources: Correlated Color Temperature and Color Rendering Index. They will be able to specify the correct color lamps using this terminology.
Optional Activities: Observe and report on the color shift of a multi-color object under a variety of light sources.
Reading: I-23color.ppt.

I-2.4 - Lighting Information Sources
Objective: This lesson will map out the wide range of lighting information resources available from commerce, government, education and professional organizations, special attention is given to web sites. Some guidance will be given on evaluating the information and its source.
Optional Activities: Order a copy of the Energy Efficient Lighting Catalog, order list of publications from the FEMP web site, report on an article or information gathered on the web or in a trade magazine.
Reading: I-24infor.ppt.

Section I-3

I-3.1 - Visual Tasks
Objective: The lesson will sensitize the students to the varied tasks that occur in a single common space. They will be taught on how to apply the IESNA illuminance selection procedure with caveats on proper use. Lighting quality issues will also be presented.
Optional Activities: Identify the many tasks that occur in rooms from pictures.
Reading: I-31tasks.ppt.

I-3.2 - Applying Light to Interior Space
Objective: This lesson will describe how room geometry, surface reflectances and the presence of windows affect the quality and level of light from light fixtures.
Optional Activities: Estimating the reflectances of surfaces in the student’s working environment.
Reading: I-32room.ppt.

I-3.3 - Measuring and Calculating Illumination Levels
Objective: Methods of how to measure illuminance, luminance, (and indirectly) reflectance will be demonstrated. The Lumen Method will be taught to calculate the illuminance from a given number of light fixtures or conversely, how many light fixtures are needed to provide a given target illuminance.
Optional Activities: Calculate an average illuminance of a given lighting system/room configuration. Evaluate how a measured lighting level could be misleading.
Reading: I-33calc.ppt.

I-3.4 - Lighting Calculations by Computer
Objective: The students will learn about the various types of computer-aided lighting design programs, and the pros and cons of each type.
Optional Activities: Evaluate the results of average illuminance and isolux contours for 3 different lighting systems and evaluate where each might be appropriate.
Reading: I-34comp.ppt.
