Certified Energy Auditor Economic Analysis and Financing Questions and Answers

Question 1

An energy auditor is evaluating two mutually exclusive projects for a client. Project A has a higher Net Present Value (NPV) but a lower Internal Rate of Return (IRR) than Project B. The client's primary goal is to maximize the absolute value added to the company. Which project should the auditor recommend and why?

Accepted Answer

Project A, because NPV is a direct measure of the total value a project is expected to add.

Answer

When projects are mutually exclusive, the Net Present Value (NPV) is generally the superior decision criterion. NPV calculates the total monetary value a project will add to the firm, which directly aligns with the goal of maximizing value. The Internal Rate of Return (IRR) can be misleading when comparing projects of different scales or cash flow patterns, as it only represents the project's percentage rate of return, not the absolute magnitude of the value created.

Question 2

A school district lacks the upfront capital for a comprehensive lighting and HVAC retrofit but wants to proceed with the project and pay for it using the energy savings generated. A third-party company offers to design, install, and finance the project, guaranteeing that the annual savings will cover the debt service payments. This financing arrangement is best described as:

Accepted Answer

An Energy Savings Performance Contract (ESPC)

Answer

An Energy Savings Performance Contract (ESPC) is a financing mechanism where an Energy Service Company (ESCO) arranges for the design, installation, and financing of energy efficiency projects, and guarantees that the resulting energy savings will be sufficient to cover the project costs over the contract term. This model allows organizations to implement upgrades without upfront capital.

Question 3

Which of the following is typically EXCLUDED from a standard Life-Cycle Cost Analysis (LCCA) for an energy efficiency measure?

Accepted Answer

Costs related to loss of employee productivity during installation

Answer

A standard Life-Cycle Cost Analysis (LCCA) includes all costs associated with owning, operating, and maintaining a system over its life. This encompasses initial capital costs, energy costs, maintenance costs, and replacement costs. While factors like employee productivity can be impacted, their costs are considered non-quantitative or indirect and are typically difficult to monetize, so they are usually excluded from the primary LCCA calculation unless a specific, rigorous methodology is employed to quantify them.

Question 4

A facility manager implemented a large-scale chiller plant optimization project and needs to verify the savings for an ESPC. The project involves multiple interactive system changes, making it difficult to isolate the impact of any single measure. According to the International Performance Measurement and Verification Protocol (IPMVP), which option would be most appropriate for this scenario?

Accepted Answer

Option C: Whole Facility

Answer

IPMVP Option C (Whole Facility) is used when energy conservation measures are expected to have a significant impact on the total energy consumption of the building, or when there are multiple, interactive measures. This method analyzes the energy use of the entire facility using utility meter data before and after the retrofit, making it suitable for complex projects where isolating the savings from individual measures is impractical.

Question 5

A utility company offers a program allowing its residential customers to finance energy efficiency upgrades, such as new insulation or a heat pump, with no upfront cost. The customer repays the loan over time through a line item added to their regular monthly utility statement. This financing model is known as:

Accepted Answer

On-Bill Financing

Answer

On-Bill Financing (OBF) is a model where a utility or a third party provides a loan for energy efficiency improvements, and the customer repays it through a charge on their monthly utility bill. This method simplifies repayment and often uses the utility payment history for credit qualification, expanding access to financing.
