1. Sierra Research January 10, 2012 Space Heating Fuel Use Distributions

2. 2 Objective Examine modeled temporal variations in fuel use Illustrate how modeled fuel use varies with ambient temperature Compare modeled daily fuel use by household to survey data

3. 3 Modeled Daily Variations in Household Wood Use

4. 4 Modeled Daily Variations in Household Oil Use 19.6 lb wood = 1 gal home heating oil (BTU basis)

5. 5 How Does Modeled Wood Use Vary with Temperature 17% increase per 10 degree drop

6. 6 How Does Modeled Wood Use Vary with Temperature 17% increase per 10 degree drop

7. 7 How Does Modeled Wood Use Compare to Survey

8. 8 How Does Modeled Oil Use Compare to Survey

9. 9 Implications Provides decision makers with understanding of household fuel use and how it varies Provides a basis for examining “fuel-switching” scenarios
