Sierra Research January 10, 2012 Space Heating Fuel Use Distributions

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 Modeled Daily Variations in Household Wood Use

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

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

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

7 How Does Modeled Wood Use Compare to Survey

8 How Does Modeled Oil Use Compare to Survey

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