Certified Energy Auditor Certification Certified Energy Auditor Economic Analysis and Financing 1 — Questions and Answers
Question 1: A life-cycle cost (LCC) analysis for a chiller replacement project must include which categories of cost over the full study period?
- First cost (purchase and installation) only
- First cost, energy costs, maintenance costs, and end-of-life disposal costs (Correct answer)
- Energy cost savings and maintenance costs only
- First cost and projected energy savings only
Correct answer: First cost, energy costs, maintenance costs, and end-of-life disposal costs
LCC analysis is a 'cradle-to-grave' methodology that captures every cost associated with an asset over its useful life — acquisition, operation, maintenance, and disposal — so that alternatives can be compared on a true total-cost basis rather than just upfront price.
Question 2: An energy project has an Internal Rate of Return (IRR) of 14%. The organization's Minimum Acceptable Rate of Return (MARR) is 10%. What is the correct economic conclusion?
- Reject the project because the IRR exceeds the MARR
- Accept the project because the IRR exceeds the MARR (Correct answer)
- Reject the project because IRR and MARR must be equal for viability
- Accept the project only if the simple payback is also under 5 years
Correct answer: Accept the project because the IRR exceeds the MARR
When a project's IRR exceeds the organization's required hurdle rate (MARR), the investment generates returns above the minimum threshold and is economically justified. An IRR below the MARR would indicate rejection.
Question 3: An auditor applies a 3% annual compound fuel escalation rate to a current energy cost of $50,000. What is the projected energy cost at the end of Year 2?
- $53,000
- $51,500
- $53,045 (Correct answer)
- $56,275
Correct answer: $53,045
Fuel escalation compounds annually: Year 1 = $50,000 × 1.03 = $51,500; Year 2 = $51,500 × 1.03 = $53,045. Using simple (non-compounded) escalation would underestimate future costs.
Question 4: Property Assessed Clean Energy (PACE) financing is distinctive among energy project funding mechanisms primarily because:
- It requires a personal credit check and is tied to the individual building owner
- Repayment is attached to the property tax assessment and transfers with the property upon sale (Correct answer)
- It can only be used for on-site renewable generation, not efficiency retrofits
- Repayment terms are limited to a maximum of five years
Correct answer: Repayment is attached to the property tax assessment and transfers with the property upon sale
PACE financing attaches repayment to the real property rather than the owner, collected through property tax bills. This means the obligation transfers to a new owner at sale and typically allows longer terms (10–25 years), improving project cash flow.
Question 5: A building owner claims the federal Investment Tax Credit (ITC) at a 30% rate on a $200,000 solar installation. What is the direct financial benefit of the ITC?
- A $60,000 reduction in taxable income
- A $60,000 dollar-for-dollar reduction in federal taxes owed (Correct answer)
- A $14,000 annual depreciation deduction spread over multiple years
- A $200,000 expense deduction taken entirely in the first year
Correct answer: A $60,000 dollar-for-dollar reduction in federal taxes owed
The ITC is a tax credit, not a deduction — it reduces the actual tax liability dollar-for-dollar. At 30% of $200,000, the owner owes $60,000 less in federal taxes, which is a more powerful benefit than an equivalent income deduction.
Question 6: If an energy auditor raises the discount rate used in a Net Present Value (NPV) analysis of a long-term efficiency project, what is the expected effect on the project's NPV?
- NPV increases because future savings become more valuable in today's dollars
- NPV remains unchanged because annual savings amounts are fixed
- NPV decreases because future savings are discounted more heavily (Correct answer)
- NPV increases because a higher discount rate shortens the effective payback period
Correct answer: NPV decreases because future savings are discounted more heavily
A higher discount rate reduces the present value of cash flows that occur in future years. Energy projects with savings spread over 10–20 years are especially sensitive to discount rate selection; using a high rate can make a financially sound project appear marginal or unacceptable.
