Question 1

_____ is planned induction of outside air to create a slight positive pressure on the structure.
A) Infiltration
B) Heat transfer
C) Conduction
D) Ventilation

Accepted Answer

Ventilation is the process of bringing fresh air into a building or structure and removing stale air. Positive pressure ventilation involves introducing outside air into the building to create a higher air pressure inside than outside. This helps prevent infiltration of outside contaminants and can improve indoor air quality.

Question 2

To determine the area of a _____, use the formula:  (base height).
A) trapezoid
B) parallelogram
C) square
D) triangle

Accepted Answer

D

Question 3

A(n) _____ barrier is the outer skin of a facility.
A) air
B) weather
C) thermal
D) vapor

Accepted Answer

The weather barrier is designed to protect a building from the elements such as rain, wind, snow, and sun. It prevents moisture from entering and air leakage from the building envelope. The other types of barriers listed (air, thermal, vapor) are also important components of a building envelope, but they do not necessarily refer to the outer skin of the building.

Question 4

Energy conservation techniques are cost prohibitive for most individuals and businesses.

Accepted Answer

While some energy conservation techniques may have higher upfront costs, over time they can result in significant savings on energy bills. In addition, many energy conservation measures can be implemented without significant cost, such as turning off unused lights and electronics or adjusting thermostats. There are also government and utility company incentives and rebates available to help offset the cost of energy efficiency upgrades.

Question 5

The framing member used in the construction of a wall will _____ the overall R-value or its effective total R-value.
A) increase
B) determine
C) reduce
D) not effect

Accepted Answer

Framing members used in the construction of a wall, such as wood or metal studs, conduct heat more easily than insulation material. This creates gaps in the insulation and reduces its effective total R-value. Therefore, the use of framing members will reduce the overall R-value of the wall.

Question 6

A cooling load calculation is used to tell the technician how much heat is escaping from the structure.

Accepted Answer

A cooling load calculation is used to determine the amount of cooling needed in a space, not how much heat is escaping from the structure.

Question 7

The lifestyle of the occupants should be the most important factor when considering energy conservation techniques.

Accepted Answer

The answer of The lifestyle of the occupants should be...

Question 8

Exposure to _____ has been linked to neurological issues.
A) cellulose
B) SPF
C) fiberglass
D) polystyrene

Accepted Answer

The answer of Exposure to _____ has been linked to...

Question 9

The "house as a system" principle states that although the home might be made up of individual components, these components come together as a whole.

Accepted Answer

The "house as a system" principle is based on the concept that all the components of a home, such as insulation, ventilation, and heating/cooling systems, work together as a whole rather than as separate entities. This principle acknowledges that the interaction between components can affect the overall performance and energy efficiency of the home.

Question 10

Weatherization is an important aspect of becoming energy efficient and helping conserve our natural resources.

Accepted Answer

Weatherization involves making adjustments to a building or home to reduce energy consumption and improve efficiency, which in turn helps conserve resources and reduce overall energy usage.

Question 11

A(n) _____ is a survey of a residence conducted to analyze the current energy requirement of the structure and its occupants as well as how that energy flow can be reduced without having a negative effect on the structure and/or occupants.
A) cost analysis
B) conservation calculation
C) energy audit
D) quality analysis

Accepted Answer

An energy audit is a survey of a residence conducted to analyze the current energy requirement of the structure and its occupants as well as how that energy flow can be reduced without having a negative effect on the structure and/or occupants. Cost analysis is a financial analysis, conservation calculation is not a common term, and quality analysis does not relate specifically to energy consumption.

Question 12

Although important, energy conservation does alter and reduce the comfort level of the occupants of the facility.

Accepted Answer

Energy conservation strategies can be designed and implemented in a way that maintains or even improves the comfort level of the occupants by optimizing energy use and ensuring efficient heating, cooling, and lighting systems.

Question 13

Calculating the infiltration load on a structure is the easiest part of a load calculation.

Accepted Answer

Calculating the infiltration load on a structure can be complicated and requires consideration of factors such as air leakage rates, building materials, and climate conditions.

Question 14

A typical comfort level for residential and light commercial buildings is _____ with a relative humidity between _____ .
A) 70°, 40% and 60%
B) 65°, 50% and 70%
C) 75°, 40% and 60%
D) 70°, 50% and 70%

Accepted Answer

A typical comfort level for residential and light commercial buildings is around 70°F with a relative humidity between 40% and 60%. This range is generally accepted as comfortable for most people and helps to maintain a healthy indoor environment.

Question 15

Generally speaking, anything that is a good conductor of electricity is a good conductor of heat.

Accepted Answer

This is because both electricity and heat are forms of energy that can be transferred through the movement of electrons or molecules. Therefore, materials that facilitate the flow of electrons (electricity) also facilitate the transfer of heat.

Question 16

_____ is the form of heat transfer in which the heat is transferred from within a substance from one molecule to another.
A) Convection
B) Conduction
C) Microwave
D) Radiation

Accepted Answer

Conduction is the form of heat transfer in which the heat is transferred from within a substance from one molecule to another through direct contact.

Question 17

As a general rule of thumb, heating devices that use combustion (natural gas, fuel oil, propane, or wood) require one square inch of ventilation for every 1,000 Btu of heat output.

Accepted Answer

This is a commonly accepted rule for ventilation requirements for heating devices that burn fuel. It's important to ensure proper ventilation to prevent the buildup of toxic gases like carbon monoxide.

Question 18

The amount of heat transferred through building materials is know as _____ .
A) heat of transmission
B) fire resistance
C) temperature difference
D) heat coefficient

Accepted Answer

The term "heat of transmission" refers to the amount of heat that is transferred through building materials. This concept is crucial in the fields of building construction and engineering, as it impacts the thermal efficiency and energy requirements of buildings.

Question 19

The _____ of energy conservation is the rate at which the total investment is recovered by the savings the customer realizes in their utility bill from the energy conservation.
A) ROI
B) ROE
C) ECR
D) IR

Accepted Answer

ROI stands for "return on investment" and is a commonly used financial metric to determine the potential profitability of a project or investment. In the case of energy conservation measures such as upgrading to more energy-efficient appliances or installing insulation, the ROI would represent the amount of time it takes for the total investment in the project to be recovered by the savings on the customer's utility bill. The higher the ROI, the more financially beneficial the energy conservation measure is.

Question 20

Energy conservation is a personal responsibility and cannot be legislated nor can it be forced upon someone.

Accepted Answer

Energy conservation relies on individual action and responsibility, and cannot be effectively enforced or mandated by legislation or coercion. Ultimately, it is up to individuals to make conscious choices about their energy use and conservation practices.
