When preserving a tree, construct a temporary fence around the tree canopy and post signs to keep out vehicles that might compact soil and construction waste that could contaminate the soil.
Image
When rigid foam insulation is applied to the exterior side of the wall cavity under the cladding, with seams taped and an air gap provided, it acts as a vapor barrier, air barrier, and rain screen.

Image
When the EIFS siding on this house gave way in high winds, it revealed severe rotting of the sheathing beneath the windows due to long-term water leakage.
Image
When the lower break-away wall gave way in coastal flooding it peeled some of the EIFS siding off with it because there was no suitable break in the siding to allow it to detach cleanly.
Image
When the soffits blew away in 140 to 160 mph hurricane winds, wind-driven rain was allowed to enter the attic.
Image
When using I-joists, make sure to fill in the gaps on each side of the blocking material to air-seal the joist bay where a wall separates conditioned and unconditioned spaces.
Image
When wiring is installed in ICF walls, openings made for wire runs should be air-sealed with caulk.
Image
When wrapping metal ducts with insulation allow two inches of overlap and staple along the seam with outward clinching staples
Image
Where the interior wall intersects the corridor wall in this multifamily building, the first intersecting wall stud is sealed to the corridor wall along both sides; other seams and penetrations in the exterior wall are also sealed
Image
Where the optimal tilt angle for PV panels is 30°, if the roof is facing due south, the tilt angle (roof pitch) can vary 0° to 60° or roof direction can vary up to 65° to east or west and the roof can still collect 90% to 100% of available solar energy.

Image
While windows typically make up only 7% of the total envelope area of a home, they are responsible for 48% of its heat loss
Image
White walls and roofs; overhangs and awnings; and operable shutters and garden walls all help to keep out unwanted solar heat gain providing cool interiors for this Florida home.
Image
Image
Whole house fans draw cool night-time air in through open windows and expel hot house air into the vented attic
Image
Image
Whole-house fans draw outside air through windows into the home and exhaust it into a vented attic
Image
Whole-house fans operate when it is cooler outside than inside to exhaust hot air from the house and replace it with cooler outside air.
Image
Whole-house fans or wind-driven cross ventilation can be used to draw air across thermal mass for a night flush strategy
Image
Wide saddle support provides sturdy support for the turn without pinching the flex duct
Image
Image
Wildfires across the United States claimed 10.12 million acres and 17,904 structures, including 9,700 homes in 2020
Image
Wind path and uplift force for a gabled roof, a hip roof, and a pyramidal (another variant of a hip) roof design

Image
Windblown embers and firebrands are the most common cause of structural fires in wildfires, followed by fires started by radiant heat igniting surfaces or breaking windows and allowing embers in, followed by direct flame contact
Image
Image
Window and door rough openings in the ICF wall are surrounded with pressure-treated wood
Image
Window attachments like insulated blinds, solar screens, and low-e storm windows provide many benefits including heating and cooling savings at a low first cost
Image
Window coverings like insulated blinds, cellular shades, sun-blocking roller shades, and low-e storm windows can provide heating and cooling energy savings
Image
Window Detail: Framed Wall with Plywood or OSB Sheathing, a WRB, and Siding (Wood, Fiber Cement, Aluminum, or Vinyl)

Image
Windows are installed as “outies” in this wall assembly using a self-adhered membrane water and air control layer with continuous exterior insulation
Image
Windows are installed in new framing in preparation for adding exterior spray foam insulation
Image
Windows are sized and positioned so only one king stud is needed on each side of the window.
Image
Image
Image
Winter storms can cause power outages while prolonged winter weather can take a toll on building structures
Image
Wintertime condensation potential for exterior storm windows can be reduced if the original window is airtight and weep holes in the storm window are open to provide a small amount of ventilation to the outside
Image
Wire hardware mesh is fastened with a staple gun and screws to the wall to prevent pests from entering the building through small holes and cracks
Image
Wiring runs are covered with canned spray foam to maintain the continuous foam layer that covers the inside and outside of these ICF block walls.
Image
Image
With balconies in multifamily buildings, it is important to establish correct structural attachment while also providing insulation in a way that minimizes thermal bridging where the balcony attaches to the building
Image
Image
With fiber cement siding, face nail rather than blind nail where the design wind speed is ≥100 mph.
Image
With fiber cement siding, place blind nails 3/4 to 1 inch from top edge and > 3/8 inch in from butt ends.
Image
With modern low-E storm windows, manufacturers offer many frame colors and the option for custom color matching
Image
Image
With the nailed block method, wood blocks are attached to the sill plate and the cripple wall plywood is attached to the block to provide shear strength for correctly bracing a cripple wall in a seismic retrofit
Image
With very few roof penetrations and a simple design, the south-facing roof provides ample space for solar panels for this net zero home.
Image
Without an exhaust fan ducted to the exterior, particles resulting from cooking can accumulate on walls and ceilings, and will be present in the air where they can damage occupants' respiratory systems
Image
Wood blocking for future PV panel installation is installed in the layers of polyisocyanurate rigid foam insulation during a flat roof retrofit
Image
Image
Wood decks that extend over vegetated slopes are very vulnerable to ignition by approaching wildfires.

Image
Wrap batt insulation around pipe loosely enough not to compress the insulation and secure with wire or tape
Image
Image
Wrong - House wrap was poorly installed, seams were not taped, and flashing tape was not installed around windows.
Image
Image
Wrong - A typical vented crawlspace in North Carolina exhibits water leakage, poor drainage, and a low-quality vapor retarder that does not cover all of the ground surface and is not sealed to the walls.
Image
Wrong - A vapor barrier should cover the top of the concrete block pier support in the crawl space.
Image
Image
Image
Image
Image
Image
Image
Image
Wrong - Air conditioning compressor unit should be sitting on concrete pad installed directly on ground.
Image
Wrong - Air filter was compressed and may not function effectively to filter return air.
Image
Wrong - Air leakage from the conditioned space to the basement foundation wall can lead to condensation or moisture issues in a conventional blanket insulation installation.
Image
Wrong - Airborne embers can float into holes in damaged vent screens and ignite flammable items in the house or accumulated debris in the vent.
