Define energy management

1. Define energy management. State the role of conservation in an effective energy management program. (3pts) 2. Why do you think there should more interest in energy management? (5pts) 3. In your opinion, what is the single most important ingredient for a successful energy management program? (3pts) 4. List five different forms or types of energy. Give an example of a conversion from each of these forms into another. (5pts) 5. Categorize the following units as those of energy or power: joules, watts, kilowatt-hours, ft-lb, calories, kW, ft-lb/min. (7pts) 6. What is the difference between energy conservation and conservation of energy? Give an example of each. (5pts) 7. An engine performs 4000 J of work in 10 seconds. What is the power output in kilowatts (kW) and in horsepower (hp)? (4pts) 8. A 100 W light bulb is accidentally left on for two days in a basement. If electricity costs $0.12/kWh, how much did this oversight cost? (3pts) 9. A household gas furnace has an output of 100,000 BTU/hr. What size electric heating unit (in kW) would you need if you decided to replace it? If the energy input for the new heating unit is rated at 32kW, what is its efficiency? (5pts) Module 2: The Energy Audit Process (15pts) 1. Which building performance measure should be used in setting up an audit procedure for a series of buildings: BTU/ft2/year or BTU/year? Why? (5pts) 2. The Lecture Slides discussed the point of making an inspection visit to a facility at several different times to get information on when certain pieces of equipment need to be turned on and when they are not needed. Using your home or work or other building as an example, list some of the unnecessary uses of lights, air conditioners, and other pieces of equipment. How would you recommend that some of these uses be avoided or reduced? What kind of automated equipment, if any, could be used to eliminate or reduce this wasteful use of energy? (10pts)
