Objectives

• Talk about grades

• Talk about project and field trip

• Review important lectures

Grades

• Your course grades are in the grade book. • I will updated the grade book on Saturday based on second

midterm project and quiz grades.

• If you feel that you deserve better than what your grade shows, you can take the final exam. • Final exam counts 25% of the final grade.

• Students who do not want to take the final exam need to inform me by e-mail about this. • The deadline for making this decision is May 3.

Review for exam

…..

Review –Electric

• Electric - fundamentals

• Electric equipment

• Design questions:

Electrical Systems

• What is NEC? What does it tell you?

• What is single phase power? What is three phase power? (related to the use of equations)

• How do you size conductors?

• What is conduit and how do you size it?

• How do you calculate electrical bills for a commercial building? For a residential building?

Residential Electrical (1Ø)

• How many phases are there?

• How many voltage levels?

• What voltages are typical?

• How does air conditioning and heating influence the required electrical load?

• How do you size the panel?

Commercial System - Panels

• How should you size the conductors?

• How should you size the panel?

• What is a branch circuit?

• How to balance branch circuits?

Commercial Electrical

• When do you need a transformer? How do you size it?

• How do calculate the current coming into a transformer?

• What do you do if no conductor is big enough?

Review - Lighting

• Light - fundamentals

• Lamps

• Design questions

Lamp Technologies

• What are three different kinds of lamps?• How do halogen lamps differ from

incandescent lamps?• How do fluorescent laps work?• How do HID lamps work?• What is a ballast? When do you need a

ballast?• What lamp has the highest/longest

CRI/lifetime/efficiency?

Lighting Design

• What is the difference between illuminance and luminance?

• What is a lumen?

• In addition to quantity of light what are other variables which influence lighting design?

Determining Required Lighting Levels

• Where do you start?

• What other pieces of information do you need to know?

• What is the difference between a lux and a foot-candle?

CU calculations

• What is CU and what does it mean?

• Where do you start when calculating CU?

• How does room geometry influence the CU?

• What is PAR? What is a CR?

• What is the difference between a base reflectance and a cavity (or effective) reflectance?

• How do you calculate effective reflectances?

CU Calculations

• When do you have to calculate the floor cavity reflectance? What do you do if it is not 0.20?

• Once you have the CU, how do you calculate the number of fixtures?

• What is S/MH and how does in influence the fixture calculation?
