Describe evaporative cooling.

Adding water vapor to the air/increasing humidity to make the air feel cooler.

Which heating system type is most likely to be found in a house built in 2006?

Forced air heating system

Which heating type is most likely to be found in a large, old elementary school?

Boiler System

hat are the 3 main uses of ventilation we discussed in class?

These uses are to provide fresh air, control temperature, and manage humidity levels.

As moist air cools, what happens to the water vapor in the air?

Water vapor condenses

What is the main difference between dry-bulb temperature and wet-bulb temperature?

Wet bulb temp takes into account the water vapor/humidity/moisture in the air.

What is the difference between R-Values and U-Values?

.

R-value represents thermal resistance. U-value represents thermal conductivity. Higher

R-value & lower U-value is better for insulation.

Describe the differences between Manufactured construction and Pole Building construction.

Manufactured construction involves using large pieces of a building which are produced

off-site, transported to the site, and then assembled.

Pole Building construction generally

utilizes a frame construction with concrete cylinders buried in the ground.

What are common applications of Post & Beam construction?

Machine sheds, Morton buildings, large rural buildings, large storage facilities

What is a stronger residential basement wall option than using bricks or concrete blocks?

Poured concrete walls- formed concrete walls

List 3 advantages and 3 disadvantages of steel as a structural material.

Reliable, strong, lightweight

High corrosion/must be painted, fireproofing/heat transfer, high cost

List 3 advantages and 3 disadvantages of wood as a structural material.

Low-maintenance, low-cost, easy to work with, readily available

Shrinking and swelling, susceptible to fungi and pests, flammable

List 3 advantages and 3 disadvantages of masonry as a structural material.

Durable, aesthetic, fire-resistant, resists pests and rot

Expensive, labor-intensive, long build times, not very strong, difficult to repair

What are the 4 main components of concrete?

Cement, fine aggregate (sand), coarse aggregate (gravel), and water

Does concrete have higher tensile strength or compressive strength?

Compressive strength

Provide 2 main reasons why concrete isn’t always mixed with more cement to be as

strong as possible.

High cost of cement

As more cement is added, concrete becomes more brittle

Does the steel in reinforced concrete provide compressive or tensile strength?

Tensile strength

What is active concrete reinforcement?

Active concrete reinforcement adds stress to the reinforcements prior to the concrete

being poured/cured. Once cured, those stresses counteract the natural stresses applied to

the structure.

Describe what the CSI Masterformat is and why it’s important.

Provides a standard classification system for organized construction project information.

This ensures information for all projects is conveyed in the same way independent of

company or organization.
