A 2,200 ft2 home with a poorly insulated ceiling is in an area with an 10-month heating season with an average outdoor temperature of 30 oF and an average indoor temperature of 80 oF.
If the owner spends $1000 on insulation, the R-value of the ceiling can be raised from 15 to 40 (ft2-oF-hr/Btu). The house is heated at 9 cents/kWhr.
1.How much money would the owner expect to save each year?
2.How long until the energy savings pay for the cost of the insulation?

You are building a new house, you can buy cheap ceiling insulation (R =11 ft2-°F-hr/Btu) or more expensive insulation (R=25 ft2-°F-hr/Btu). If the winter outside average temperature is 45°F for 4 months in HSV, and 3 months of summer (85°F). Assume that you keep the house at 70°F. • What is difference in electricity costs if electricity cost are 8 cents/kW hr? (Ahouse = 40 x30 ft) • If the difference in cost is $1,200 at time of installation, what...
