Attic VentilationAttic 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.

Attic Ventilation: Soffit VentAn 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 VentA 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.

Attic Ventilation: Gable VentA screened, louvered opening in the gable that allows for heat to escape through the gable ends.

Attic Ventilation: Roof TurbineA 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.

BackhoeA 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. 23 inches wide

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.

Code Requirements: Residential StairsThe stairs shown to the right were measured with a tread depth of 11 1/4” while the risers were at a height of 7 ½”. The IBC states that for residential stairs the treads shall measure a minimum of 10” and the risers shall measure a maximum of 7 ¾”. These stairs DO meet the IBC.

Concrete Joints: Control JointA concrete control joint is placed in concrete to keep the material from cracking during normal expansion and contraction due to temperature changes.

Concrete Joints: Isolation JointIsolation joints are used to relieve flexural stresses due to vertical movement of slab-on-grade applications that adjoin fixed foundation elements such as columns, building or machinery foundations, etc.Isolates Slab from Wall.

Concrete Masonry Unit A block made of hardened concrete. The unit has hollow cores in the inside that allow for the installation of reinforcement. CMUs allow for quick and affordable construction. Typical dimensions are 8”x8”x16”. One course of CMUs are equal to three courses of masonry brick.

Doors: TransomA transom is a fixed window over a door or another window.

Doors: SidelightsA sidelight is a window, usually with a vertical emphasis, that sits on either side of a door.

Electrical Components: Transformer BoxA electrical transformer is used to reduce the high voltage in power transmission lines down to voltage that is suitable for use in normal applications. They can either be mounted on a pole for overhead service or in a box like this one for underground service.

Electrical Components: Service HeadThe service head is the location where the electrical service is routed from the high voltage lines down conduit and into the meter and meter box assembly.

Electrical Components: MeterThe meter is a device that measures the amount of electricity supplied to the residence.

Electrical Components: Service PanelThe location where electricity is distributed throughout the home to various circuits. Also the place where the electricity can be turned on and off.

Electrical Components: Duplex ReceptacleA duplex receptacle is a device used to transfer the electrical current from the wiring in the walls to the walls’ surface. They make a connection point so devices can be hooked up to and removed from the electrical current with ease.

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.

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.

Heat PumpA 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.

InsulationInsulation 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.
