An in-line exhaust fan supplements the ability to exhaust moisture-laden air and lint from a dryer
Image
An independent ducted dehumidifier draws air from and supplies air to the living space using its own ducts, not ducts that are connected to the HVAC system
Image
An indoor water heater should be secured to the wall’s studs to prevent it from moving or tipping over in the event of an earthquake
Image
An infrared camera can show heat transfer and air leaks not visible to the naked eye.
Image
An innovative U-shaped heat pump offers SEER 15 efficiency and operation with smart phones

An interior shade that closes from the bottom up can work in conjunction with an exterior overhang to block lower-angle sunlight while still allowing view through the upper portion of the window that is shaded by the overhang.
Image
An IR camera image shows gaps around HVAC flue pipes allow conditioned air to leak through blown fiberglass into the attic
Image
Image
An NFRC glazing system energy performance label will report U-factor, solar heat gain coefficient, visible transmittance, and air leakage; if the window is ENERGY certified, the ENERGY STAR label will be located next to the NFRC label

Image
An on-demand hot water pump speeds water delivery to the low-flow plumbing fixtures for significant water and energy savings.
Image
An outdoor shower off the master bathroom keeps heat and humidity outside for this hot-humid climate home.
Image
An outside air duct brings in fresh air that is filtered and distributed to the home through the heat pump’s air handler and ducts. The system is electronically controlled in conjunction with the home’s exhaust fans for balanced ventilation.
Image
An ultra-efficient layer of R-20 rigid foam foundation insulation covers the ground underneath the vapor barrier and radiant floor loops, which will circulate water heated by an ultra-efficient geo heat pump.
Image
An underground fuel tank is anchored onto poured-in-place concrete counterweights.
Image
An uninsulated (or existing insulated) basement slab is retrofitted to reduce moisture transmission by sealing with epoxy paint.
Image
An unvented cathedralized attic has the air, thermal, and vapor control layers at the roof line

Image
Anchor bolts should be at least 1/2-inch diameter and should be embedded at least 7 inches into the foundation, spaced not more than 6 feet apart, and between 3.5 and 12 inches from each end of the sill plates.
Image
Image
Anchorage failure in sliding glass doors due to negative pressures from hurricane force winds.
Image
Anchoring a fuel tank to a concrete slab is recommended to avoid displacement if flooding occurs.
Image
Anchoring hardware is used to tie down equipment and components of the home to resist high winds and hurricanes.
Image
Anemometers, including the vane style (lower) and hotwire style (upper) are used to measure air velocity to calculate airflow
Image
Angle support framing is added to brace a long gable overhang constructed using the ladder framing method.
