Household Energy Efficiency
LEARNING TARGET: I can identify the features that effect energy efficiency in a home and discuss how to modify them to be more effective.
CH Q
How can features in a home affect the energy efficiency of a home?
VOCAB:
Passive-energy design trade-offs
maximizing energy efficiency without machines
compromise
(giving up something to get something “better”)

4. PROCEDURE AND DATA
MATERIALS:
PROCEDURE: Read on pg. D silently Write a summary sentence for each section (7)
DATA: WS Ideas about energy
Update questions 1-13 providing evidence from the book or journal

5. DISCUSSION
What are some of the trade-offs of improving energy efficiency in the home?
Does it save more energy to install an efficient heating system or to replace incandescent lightbulbs with compact fluorescent bulbs? Explain.
initial cost to get back over long time
Heating (cooling) is most of the energy used in a home during most times of year – even though old incandescent lights are very inefficient, CFL or LED won't save "that much"

6. ANALYSIS
