Question 1

_____ is planned induction of outside air to create a slight positive pressure on the structure.&#10;A) Infiltration&#10;B) Heat transfer&#10;C) Conduction&#10;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).&#10;A) trapezoid&#10;B) parallelogram&#10;C) square&#10;D) triangle

Accepted Answer

D

Question 3

A(n) _____ barrier is the outer skin of a facility.&#10;A) air&#10;B) weather&#10;C) thermal&#10;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.&#10;A) increase&#10;B) determine&#10;C) reduce&#10;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 8

Exposure to _____ has been linked to neurological issues.&#10;A) cellulose&#10;B) SPF&#10;C) fiberglass&#10;D) polystyrene

Accepted Answer

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

Question 9

The &#34;house as a system&#34; 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.
