Round 1: Energy Accounting & Benchmarking

Front

What is a measurement of power?

Back

d and b (Btu/hour, kWh) are measurements of power.

Front

How many MMBtu are in one Futures Contract of natural gas (methane)?

Back

One Futures Contract of natural gas is worth 10,000 MMBtu.

Front

What tools are useful in measuring the combustion efficiency of a boiler?

Back

Hand-held flue gas analyzer, temperature probes, and camera.

Front

How many MMBtu’s are contained in 140,000 gallons of #2 fuel oil?

Back

140,000 gallons of #2 fuel oil contain 19,600 MMBtu.

Front

What is the maximum amount you can pay for an energy efficient air compressor with a savings of $12,000 per year over 14 years at a MARR of 12%?

Back

The maximum amount is $79,536.

Front

Define MARR in the context of energy investments.

Back

MARR stands for Minimum Acceptable Rate of Return, the lowest return rate an investor is willing to accept.

Front

What does Btu stand for?

Back

Btu stands for British thermal unit, a measure of heat energy.

Front

Explain the significance of combustion efficiency in energy auditing.

Back

Combustion efficiency measures how effectively a fuel is converted into usable energy, impacting energy costs and emissions.

Front

What is the formula to calculate energy savings from an energy-efficient appliance?

Back

Energy Savings = (Old Appliance Energy Use - New Appliance Energy Use) x Time.

Front

What is the role of a hand-held flue gas analyzer?

Back

It measures the composition of flue gases to assess combustion efficiency and emissions.
