Image
A seismic snubber is a type of bracket specifically designed to anchor heavy equipment to the floor to restrain it in the event of an earthquake.
Image
A self-adhering weather-resistant barrier is installed over the existing sheathing of this retrofit home to provide air sealing and a drainage plane before installing new metal and wood siding on the home.
Image
A self-sufficient water system for a home could include a rooftop cistern and solar thermal water heater.
Image
A shaded fuel break is created on forested lands when trees are thinned, tree canopies are raised by removing lower branches, and the understory vegetation is managed to reduce the fire threat.
Image
A shallow, open floor plan allows free flow of cross ventilation through the house
Image
A sill gasket is installed under the two layers of fire-rated gypsum providing air sealing at the foundation slab in this 2-hour fire wall separating two units in a multifamily row house building
Image
A sill-sealing foam gasket is placed under 8-inch plywood base and two beads of caulk air seal the 2x6 sill plate to it; two more beads of caulk will top the 2x6 which will serve as a spline for the SIP wall panel.
Image
A simple kit for anchoring a TV, appliance, or furniture to a wall may include straps, attachment hardware, and screws for attaching both to the appliance and to the wall
Image
A simple vented attic with good air-sealing of the drywall ceiling air barrier, air flow from soffit vents to ridge vents protected by ventilation baffles, and lots of insulation covering the attic floor is unlikely to encourage ice dams.
Image
A single ductless heat pump heats and cools the country’s first DOE Zero Energy Ready certified manufactured home.
Image
A single-story house floor plan showing braced wall line locations at A through E and 1 through 5
Image
A site-built rafter roof with a raised top plate allows for more insulation underneath.
Image
A small, single-zone cooling system such as this ductless mini-split heat pump can be a very effective way to provide emergency cooling with a low power draw on a backup power system.
Image
A solar tube provides more natural light while maintaining privacy for this bathroom.
Image
A sprayer-applied waterproofing covers the grout-filled top course of concrete foundation blocks to prevent moisture migration from the ground into the framing.
Image
Image
A static pressure measurement is taken on this air handler using probes on the supply and return sides of the fan.
Image
A storm water management system channels rainwater to retention chambers buried in the front yard.
Image
A strip of OSB sheathing is installed along the perimeter when retrofitting a flat roof with a parapet
Image
A structural spline made of a solid 2x is used where needed to meet structural load requirements at SIP panel seams
Image
Image
A supplemental dehumidifier is integrated with the home’s HVAC air handler to provide extra dehumidification when needed
Image
A surface spline reduces thermal bridging much more than a structural spline at SIP panel seams
Image
A swale and berm can be installed together across a slope to slow the downhill flow of water.
Image
Image
A technician assembles the spray sealant injection system to seal HVAC ducts from the inside
Image
Image
A tempered glass window can be identified by the “bug” or white etched label at one corner of the window.
Image
A thermosiphon solar hot water system heats a fluid in the solar collector; the heated fluid heats potable water in a roof top tank.
Image
