NABCEP Energy Efficiency & Conservation Techniques 3

Question 1

Which federal program sets minimum energy efficiency standards for appliances and equipment in the US?

Accepted Answer

DOE Appliance Standards Program

Answer

The DOE Appliance Standards Program establishes legally mandatory minimum efficiency levels for appliances, lighting, and equipment sold in the US.

Question 2

What is the primary purpose of a duct blaster test?

Accepted Answer

Quantify air leakage from the duct system

Answer

A duct blaster pressurizes the duct system and measures leakage to identify where conditioned air is being lost before delivery.

Question 3

The Seasonal Energy Efficiency Ratio (SEER) is used to rate the efficiency of:

Accepted Answer

Air-source heat pumps and air conditioners

Answer

SEER measures cooling output divided by electrical energy input over a typical cooling season, used for rating air conditioners and heat pump cooling mode.

Question 4

In an energy audit, the measure of cost-effectiveness comparing first-year savings to installation cost is called:

Accepted Answer

Simple Payback Period

Answer

Simple payback period divides upfront cost by annual energy savings to determine how many years until the investment is recovered.

Question 5

Which window property most directly determines how much solar heat gain enters a building?

Accepted Answer

Solar Heat Gain Coefficient (SHGC)

Answer

SHGC measures the fraction of incident solar radiation that passes through a window as heat; lower SHGC reduces unwanted solar heat gain.
