What is the baseline when measuring financial performance of a retrofit energy efficiency action?

The baseline is the energy use measured before the retro-fit was implemented

The baseline is the adjusted post-retrofit energy usage documentation

The baseline is what the energy costs would have been if the retro-fit had not been implemented

None of the above

You are measuring the performance of an energy efficiency program. Multiple interacting energy conservation measures have been implemented in the building. Which IPMVP option would be most suited?

Option A: Continuous measurement

Option B: Retrofit isolation with all parameter measurement

Option C: Whole facility

Option D: Calibrated simulation

You are measuring a retrofit energy conservation measure. The values of relevant parameters are well known : eg the operating hours of the equipment are available from the operating schedule of the plant. The equipment concerned was equipped with a submeter both before and after the retrofit. Which IPMVP option would be most suited?

Option A: Retrofit isolation with key parameter measurement

Option B: Retrofit isolation with all parameter measurement

Option C: Spot measurement

Option D: Continuous measurement

Which of the following calculations of savings is recommended by IPMVP?

Savings = baseline energy use before the retrofit � energy use after the retrofit

Savings = baseline energy use before the retrofit � energy use after the retrofit, with adjustment for changes to relevant factors

Savings = baseline energy use measured after improvement + post-retrofit energy usage

none of the above

Which method would you use to measure a variable load?

Partial facility measurement

Key parameter measurement

Spot measurement

Continuous measurement

IPMVP is intended to prescribe contractual terms between buyers and sellers of efficiency services, and to help in the selection of a measurement and verification approach that best matches the project costs and savings magnitude, technology specific requirements, and risk allocation between the buyer and seller.

The financial value of your savings will depend on how much you pay for energy, and how those payments are calculated. To forecast or express the energy savings in financial terms, what will you'll also need to consider?

Evaluation of rate structure, tariff options, and price stability to support the project over the long term

Evaluation of measurement options, monthly price reports, quarterly settlement and reconciliation

How often you'll measure the rates, tariff payments, and reconciliation of payments

All of the above

The following data was collected about a production machine. At the end of week 1 a retrofit energy efficiency implementation was performed on the machine. Based on this data, has the retrofit improved the performance of the machine? Consumption measured in week 1: 4,000 kWh Production output in week 1: 200 units Consumption measured in week 2: 5,000 kWh Production output in week 2: 300 units

Yes

No � it is the same as before

No � it has got worse

Which of the following factors can impact savings achieved by a retrofit?:

Retrofit design and performance (ESCO-controlled)

Facility characteristics and operations (owner-controlled)

Maintenance (ESCO and/or owner controlled)

Weather and energy prices (outside of either control)

All of the above

Adjustments typically fall into two categories: routine and non-routine. Routine adjustments are adjustments for changes in parameters that can be expected to happen throughout the post-retrofit period, and for which, a relationship with the energy use/demand can be identified. These are often seasonal or cyclical.
