1. You determine that a home’s heating costs comprise 35% of the household’s utility budget and you calculate that replacing a furnace with a newer unit will reduce heating costs by 35%. What percentage of overall utility savings would you expect to result from this single measure?

A. 8%

B. 12%

C. 20%

D. 35%

2. A $7,000 energy retrofitting job has an expected simple ROI of 7 years, but the customer is also expecting one rebate for $2,000 and another for $1,000? What is the adjusted post-rebate ROI?

A. 3 years

B. 4 years

C. 7 years

D. 11 years

3. If an energy retrofitting job is expected to save $900/year in fuel costs, what is the maximum job price to preserve an ROI of ≥ 15%?

A. $1,500

B. $6,000

C. $13,500

D. $15,000

4. You expect an energy retrofitting measure to save 10% on your annual heating bill. You expect this year’s heating bill to be $1,000, but you also project that the price of heating fuel will rise 10% per annum. According to these projections, how much do you expect this measure to save over the course of the next three heating seasons (this season and the successive two seasons)?

A. $231

B. $200

C. $300

D. $331

5. Excluding any rebates, which suggested energy retrofitting measures would you expect to have the highest ROI in a hot-cold climates such as Chicago?

A. blowing in cellulose to insulate attic from R-4 to R-40 – this question is somewhat subjective but measures instincts and knowledge of prevailing job costs. B.-D. could all lead to substantial savings, but pricier than A. in relation to their expected payback

B. replacing double-pane windows with triple-pane windows

C. insulating sub-grade basement

D. replacing a 60-gallon natural gas water heater with 2 on-demand water heaters
