Air Barrier Paper•Standard approach to control infiltration•Can be located on the interior or exterior wall framing•Installed under siding

Attic Ventilation

• Allows water vapor to escape and keeps the house cooler in the summer by preventing solar heat

• Four types:– Soffit vent- creates the required intake ventilation at the eave– Ridge vent- effective because its located at highest point on roof– Gabled vent- located high in the wall at opposite ends of the attic. Helps

create cross draft in a wind– Through roof vents- resemble inverted cake pans and are flashed into

Code Requirements•22 ½ in from floor to sill•Height = 33 ½ in•Width = 28 in•Meets all requirements for building code•Suitable for egress

•Tread = 10 in•Riser Height = 7 ¾ in•Nosing = 1 in

Concrete Joints

•Control joint- an intentional, linear discontinuity in a structure or component, designed to form a plane of weakness where cracking can occur in response to various forces so as to minimize or eliminate cracking elsewhere in the structure

• Isolation Joint- joints that isolate the slab from the wall, column, or drainpipe

Concrete Masonry Unit (CMU)

• A block of hardened concrete, with or without hollow cores, designed to be laid in the same manner as a brick or stone.

• Most common block dimensions 8x8x16

• Notice that the height of 3 modular stacked bricks is equal to 1 CMU block

Electrical Components•Power pole- used to support both electric power distribution lines and telecommunication lines ass well as there associate equipment•Transformer Box- a device that transfers electrical energy from one circuit to another through inductively coupled conductors• Service Head- is a weatherproof entry point for above ground electrical wiring or telephone lines into a home or business• Meter- is a device that measures the amount of electrical energy supplied to or produced by a building

Service panel- a component of an electricity supply system which divides an electrical power feed into different circuits

Duplex receptacle- connectors used for main electricity

Framing Elements

Front End Loader

Gypsum Board• an interior facing panel consisting of gypsum core sandwiched between paper faces• also called drywall or plasterboard

Heat Pump• Advantage: can change conditions rapidly and also control humidity• Disadvantage: very noisy and difficult to zone• Compressor/Condenser- the outside unit of heat pump. Fan pulls air across a line of refrigerant and changes temperature

Air Handling unit- moves and conditions air through duct work. A fan sucks in new and return air and recirculates it

Insulation- a material that has low thermal conductivity. Used to keep building warm in the winter and cool

during the summer

Batt BlanketLoose Fill

Lintel• a beam that carries the load of a wall over the opening of door or window•steel

Mortar•½ in mortar joint• Concave troweled•Apartment building•Maybe type S mortar

Oriented Strand Board• a non veneered building panel composed of long shreds of wood fiber oriented in specific directions bonded together under pressure• 4x8

Plumbing

• Watercloset 3 in drain pipe

• Lavatory 1 ½ in drain pipe

• Drop in sink

Plywood• a wood panel composed of an odd number of layers of wood veneer bound together under pressure• veneer- a thin layer, sheet, or facing made from slicing thin pieces from a tree• 4x8

Radiant Barrier• a reflective foil placed adjacent to an airspace in roof or wall assemblies as a deterrent to the passage of infrared energy

Rebar• ½ in #4 rebar• the deformation on the bar are there for the concrete to have more surface area to hold onto. It increases the strength of the bond

Steep Roof Drainage• gutter- channel that collects rainwater runoff

• Downspout- metal tube that carries rainwater from gutter to ground

•Splashblock- a piece of plastic or other durable material that is laid under downspout and diverts water from the base

Steep Roof Materials• Underlayment- protects roof sheathing and structure from moisture

•Shingle- small units of water resisting material laid onto roof in overlapping patterns to make roof water tight
