Household Energy Efficiency Mar 13 / 14 Act D 71 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”)

PROCEDURE AND DATA MATERIALS: PROCEDURE: Read on pg. D98-102 silently Write a summary sentence for each section (7) DATA: WS 53.1 Ideas about energy Update questions 1-13 providing evidence from the book or journal

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"

ANALYSIS - Discuss and answer Q 1 on pg. D 103 ANS CHALLENGE Q How can features in a home affect the energy efficiency of a home? A: using renewable sources that are efficient in energy conversion (passive systems best) HOMEWORK Test Unit D - Mar Complete/Organize all WS and Vocab packet
