Energy Auditing And Conservation Quiz

1.

Which of the following is NOT commonly examined in an energy audit?

A.

Lighting
B.

The amount of exercise done by the family
C.

Air leaks
D.

Insulation

Correct Answer
B. The amount of exercise done by the family

Explanation
An energy audit is a process that examines various aspects of energy consumption in a building or household. It typically focuses on identifying areas where energy is being wasted or inefficiently used. Lighting, air leaks, and insulation are commonly examined in an energy audit because they directly impact energy consumption. However, the amount of exercise done by the family is unrelated to energy usage and therefore is not commonly examined in an energy audit.

What contributes significantly to global warming?

A.

Exercising and producing body heat
B.

Production of nitrogen
C.

Turning on the heat in your house
D.

Carbon dioxide emissions

Correct Answer
D. Carbon dioxide emissions

Explanation
Carbon dioxide emissions contribute significantly to global warming because carbon dioxide is a greenhouse gas that traps heat in the Earth's atmosphere. When carbon dioxide is released into the atmosphere through human activities such as burning fossil fuels and deforestation, it accumulates and creates a thick layer that prevents heat from escaping into space. This leads to a rise in global temperatures, causing climate change and various adverse effects on the environment, including melting ice caps, rising sea levels, and extreme weather events.

True or FalseA global temperature change of 1 degree Celsius is no big deal. Such a small temperature change can have no significant effect.

A.

True
B.

False

Correct Answer
B. False

Explanation
A global temperature change of 1 degree Celsius can actually have significant effects. Even a small increase in temperature can lead to drastic consequences such as rising sea levels, melting ice caps, and extreme weather events. It can disrupt ecosystems, harm biodiversity, and impact human health and livelihoods. Therefore, it is incorrect to say that such a temperature change is no big deal.

Which of the following organizations is not directly involved in improving energy efficiency?

A.

ECGC
B.

LEED
C.

ASHRAE
D.

RESNET

Correct Answer
A. ECGC

Explanation
ECGC is not directly involved in improving energy efficiency. ECGC stands for Export Credit Guarantee Corporation of India, which is a government-owned company that provides credit insurance to exporters. It is not specifically focused on energy efficiency initiatives or activities. On the other hand, LEED (Leadership in Energy and Environmental Design), ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers), and RESNET (Residential Energy Services Network) are all organizations that are directly involved in improving energy efficiency through various means such as setting standards, providing certifications, and promoting sustainable practices.

What does the acronym ASHRAE stand for?

A.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers
B.

The Asian Society of Heating, Refrigerating, and Air-Conditioning Engineers
C.

The American Society of Heating, Refrigerating, and Air-Conditioning Experts
D.

The American Society of Hiking, Rowing, and Adventure

Correct Answer
A. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers

Explanation
The correct answer is The American Society of Heating, Refrigerating, and Air-Conditioning Engineers. ASHRAE is an international professional organization that focuses on the advancement of heating, ventilation, air conditioning, and refrigeration systems. They provide resources, guidelines, and standards for the industry and promote sustainable and energy-efficient practices in the field.

Which of the following bulbs are most energy-efficient?

A.

Incandescent light bulbs
B.

T8 fluorescent light bulbs
C.

T12 Fluorescent light bulbs

Correct Answer
B. T8 fluorescent light bulbs

Explanation
T8 fluorescent light bulbs are the most energy-efficient among the given options. Compared to incandescent light bulbs, which produce light by heating a filament, T8 fluorescent bulbs use less energy because they produce light through the excitation of mercury vapor. T12 fluorescent bulbs are less energy-efficient than T8 bulbs because they have a larger diameter and consume more power. Therefore, T8 fluorescent bulbs are the best choice for saving energy and reducing electricity costs.

True or FalseDetecting and fixing energy leaks can help you save 5 to 30 percent of energy annually.

A.

True
B.

False

Correct Answer
A. True

Explanation
Detecting and fixing energy leaks can indeed help save 5 to 30 percent of energy annually. Energy leaks refer to any inefficiencies or wastage in the energy systems of a building or equipment. By identifying and addressing these leaks, such as through insulation improvements or sealing air leaks, energy consumption can be significantly reduced. This in turn leads to energy savings, which can range from 5 to 30 percent depending on the extent of the leaks and the effectiveness of the fixes implemented. Therefore, the statement "True" accurately reflects the potential energy savings achievable through detecting and fixing energy leaks.

The leaks seen in the following picture:

A.

Are useful since they leak out hot air making your house cooler.
B.

Are favorable because the drafts provide a cool breeze.
C.

Decrease your energy efficiency and should be sealed.
D.

Increase energy efficiency because they circulate air.

Correct Answer
C. Decrease your energy efficiency and should be sealed.

Explanation
The leaks seen in the picture decrease energy efficiency and should be sealed. Leaks in a house allow air to escape, causing a loss of conditioned air and making it harder to maintain a comfortable temperature. This can result in increased energy consumption and higher utility bills. Sealing these leaks is important to improve energy efficiency and reduce energy waste.

Reducing carbon emissions so that we can reduce greehouse effects

A.

Is really not an issue since it has not been scientifically proven.
B.

Up to the government only since they are the leaders.
C.

Is the sole responsibility of industrial companies which emit large amounts of carbon dioxide.
D.

Is up to all of us. We all use energy in some shape or form and by reducing our carbon footprint by being more energy-efficient is as important as the government's involvement as well as manufacturing companies and the like.

Correct Answer
D. Is up to all of us. We all use energy in some shape or form and by reducing our carbon footprint by being more energy-efficient is as important as the government's involvement as well as manufacturing companies and the like.

Explanation
The correct answer is that reducing carbon emissions is up to all of us. This is because we all use energy in some way, and by being more energy-efficient and reducing our carbon footprint, we can contribute to the overall reduction of greenhouse effects. While the government and industrial companies also play a role, individual actions are equally important in addressing this issue.

Which of the following best describes an energy audit?

A.

A formal examination of a business' financial situation
B.

Counting how many calories you consume per day
C.

An analysis of energy flows within a building or a process
D.

Burning calories at the gym

Correct Answer
C. An analysis of energy flows within a building or a process

Explanation
An energy audit involves analyzing energy flows within a building or a process. It is a systematic process that helps identify areas where energy is being wasted and provides recommendations for improving energy efficiency. This examination helps businesses and organizations understand their energy consumption patterns, identify energy-saving opportunities, and make informed decisions to reduce energy costs and environmental impact.
