Air Barrier PaperAir barrier paper is a membrane that is applied to the sheathing that serves to
reduce the leakage of air between the interior and exterior of a structure. Also protects the
shell from moisture during construction.

Attic Ventilation Attic ventilation is required to vent
heat and moisture from the attic of buildings. It’s essential for proper temperature and moisture control.
Four common types of ventilation include soffit vents, ridge vents, gable vents, and roof turbines.
![Page 4: Visual Dictionary-Pilaster](https://reader036.fdocuments.in/reader036/viewer/2022062407/55d53db9bb61eb2f678b46b8/html5/thumbnails/4.jpg)
Attic Ventilation: Soffit Vent
An opening under the eave of a roof, used to allow air to flow into the attic or the space below the roof
sheathing.Allows for the release of heat from the soffit area. This soffit vent is made from a piece of vinyl siding
designed for use as a soffit vent.

Attic Ventilation: Ridge Vent
A long, open assembly that allows air to circulate in and out of a gable roof at the
ridge. Allows for the release of the buildup of heat from the underside of a
gable roof.
![Page 6: Visual Dictionary-Pilaster](https://reader036.fdocuments.in/reader036/viewer/2022062407/55d53db9bb61eb2f678b46b8/html5/thumbnails/6.jpg)
Attic Ventilation: Gable Vent
A screened, louvered opening in the gable that allows for heat to escape through the gable ends.

Attic Ventilation: Roof Turbine
A turbine vent is a passive ventilation device that exhausts humid, hot air from
an attic. Some forms of turbines are equipped with an electric motor.
![Page 8: Visual Dictionary-Pilaster](https://reader036.fdocuments.in/reader036/viewer/2022062407/55d53db9bb61eb2f678b46b8/html5/thumbnails/8.jpg)
Backhoe•A backhoe is a is a piece of excavating
equipment consisting of a digging bucket on the end of a two piece, hydraulic arm. It can be a
piece of detachable equipment for a tractor or can be a dedicated unit. It’s used for excavating
foundations, septic systems, and for digging various holes.
•This backhoe was detachable, of small scale, and had a 24” wide bucket.

Code Requirements: Egress From Window
The IBC for emergency exit and rescue from a window requires that the net window area when open be equal to or greater than 5.7’ sq. for second floor bedrooms and for the sill to be no more than 44” AFF. It also states that the opening area of window should be at minimum, 24” wide and 34” high. The window to the right meets the AFF requirement at 26” AFF, but fails to meet the sq. footage requirement. The opening measured 5.272 sq feet and 23” high and 33” wide.

can either be mounted on a pole for overhead service or in a box like this one for underground
service.

Front End LoaderA front end loader is a piece of equipment primarily used to "load" material (asphalt, demolition debris,
dirt, feed, gravel, logs, raw minerals, recycled material, rock, sand, wood chips, etc.) into or onto
another type of machinery. Can also be used to dig or move fill on the jobsite.
![Page 52: Visual Dictionary-Pilaster](https://reader036.fdocuments.in/reader036/viewer/2022062407/55d53db9bb61eb2f678b46b8/html5/thumbnails/52.jpg)
Gypsum BoardA construction material used for wall and ceiling
coverage inside buildings. Gypsum is made using panels made of gypsum plaster pressed
between two thick sheets of paper, then kiln dried. Often called sheetrock or drywall.
![Page 53: Visual Dictionary-Pilaster](https://reader036.fdocuments.in/reader036/viewer/2022062407/55d53db9bb61eb2f678b46b8/html5/thumbnails/53.jpg)
Heat Pump
A heat pump is a device that uses a refrigeration cycle either to heat or cool a building by passing air or water over either the evaporating or condensing coils.
The compressor/evaporator moves the coolant around through the unit to facilitate operation. The air handler moves the physical air around through the duct work and across the condenser.
One advantage is the affordability of the unit to purchase and operate.
The major disadvantage of the heat pump is its inability to operate well at very low temperatures and thus requiring a back-up system.
![Page 54: Visual Dictionary-Pilaster](https://reader036.fdocuments.in/reader036/viewer/2022062407/55d53db9bb61eb2f678b46b8/html5/thumbnails/54.jpg)

Insulation
Insulation refers broadly to any object in a building used as insulation for any purpose. Whilst the majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation.
Its primary use is to reduce the effects of the temperature of the outside ambient air and/or the air in adjoining regions.
![Page 56: Visual Dictionary-Pilaster](https://reader036.fdocuments.in/reader036/viewer/2022062407/55d53db9bb61eb2f678b46b8/html5/thumbnails/56.jpg)

LintelThe lintel is the horizontal crosspiece over an
opening, such as a door, window, carrying the weight of the masonry above it. Its used in CMU and
masonry construction to span across openings. Two common lintel types are angle iron and concrete.
This is an angle iron type.

Plumbing: Vent PlumbingPlumbing vents allow for air to enter the piping
system and prevent a suction from forming in piping. It allows for free drainage. This vent was located over the kitchen, so I’m assuming that it
serves to vent the sink and dishwasher drains.

PlywoodPlywood is a type of engineered wood made
from thin sheets of wood, called plies or wood veneers. The layers are glued together so
that adjacent plies have their grain at right angles to each other for greater strength
