Question 1

Which ASHRAE audit level involves a detailed analysis of capital-intensive modifications and requires engineering calculations?

Accepted Answer

Level III – Detailed Analysis of Capital-Intensive Modifications

Answer

ASHRAE Level III audits involve detailed engineering calculations for capital-intensive modifications to identify their costs and savings.

Question 2

In an energy audit, what does the term 'energy use intensity' (EUI) measure?

Accepted Answer

Energy consumption per square foot of floor area per year

Answer

EUI is expressed in kBtu per square foot per year and allows comparison of energy performance across similar building types.

Question 3

A blower door test during an energy audit primarily quantifies which building characteristic?

Accepted Answer

Air infiltration rate of the building envelope

Answer

A blower door depressurizes the building to measure air leakage, expressed in CFM50 or ACH50, revealing envelope tightness.

Question 4

When benchmarking a facility against ENERGY STAR Portfolio Manager, a score of 75 or above indicates the building is:

Accepted Answer

In the top 25% of energy performers among similar buildings

Answer

An ENERGY STAR score of 75 or higher means the building performs better than 75% of similar buildings nationwide, qualifying it for ENERGY STAR certification.

Question 5

During a lighting audit, what is the purpose of measuring illuminance with a light meter?

Accepted Answer

To verify that light levels meet recommended foot-candle standards for the task

Answer

Measuring illuminance in foot-candles or lux verifies whether light levels meet IES recommended values for specific tasks and identifies over-lit or under-lit areas.
