Image
Image
The elevated concrete floor over this concrete column foundation uses rigid foam on its interior surface to reduce thermal bridging and risk of floodwater damage
Image
The ENERGY STAR logo indicates products that have been verified to meet energy efficiency and performance criteria.
Image
The existing dark tile roof on this home (top photo) was covered with a light -colored coating on day 6 (middle photo), resulting in a significant reduction in attic temperature and cooling energy consumption (bottom)
Image
The flat retrofit foundation plate is used to connect the concrete foundation to the sill plate from the exterior of the building as part of a seismic retrofit
Image
The flush cut method for seismic retrofit bracing of a cripple wall allows the plywood sheathing to be attached directly to both the cripple studs and the notched section of the mudsill
Image
The frequency, duration, and intensity of extreme heat events have increased every decade since the 1960s
Image
Image
The furring strips that provide a drainage gap behind the lap siding are wrapped with ≤ 1/8-inch screen at the top and bottom of the wall to keep out bugs and burning embers.
Image
The geometry of this roof encouraged drifting of snow leading to heavy accumulation between the gables
Image
The goal of foundation moisture management is to construct the basement, crawlspace, or slab in a way that keeps moisture from getting in in the first place
Image
The green framing is lumber that was pressure treated with borate to increase its resistance to termites, mold, and moisture
Image
The icicles and the bare spot along the left roof ridge indicate that heat from the second-story room may be heating the underside of the roof deck, melting the snow and likely leading to ice dam formation.
Image
The IR image on the right shows the sun is heating the southeast-facing wall of this concrete-block house to 36C (97F); this corner of the home would not be a good place for a cool room due to lack of shading and insulation
Image
Image
The light-colored exterior roll-down shades on this building, and the shaded entryway provide very effective control of solar heat gain
Image
The minimum required plumbing connections and trim for fire sprinkler connection to municipal water with a standalone wet sprinkler system.

Image
The number of days per year that the temperature exceeds 90°F is expected to increase throughout the contiguous U.S. when comparing mid-century (2036-2065) to near-present (1976-2005)
Image
The operable windows in this house are located at occupant level to provide comfort ventilation.
Image
The piles of this foundation were well embedded and survived floodwaters from Hurricane Katrina.
Image
The pilings for this building are showing signs of failure due to a poor siting decision to locate the home too close to the surf.
Image
The plywood panels on the underside of this house blew away in hurricane wind speeds of 105 to 115 mph due to corrosion of existing nails, excessive space between nails, and use of nails instead of screws.
Image
The polyethylene ceiling vapor barrier is sealed to form an air barrier around the exhaust fan in this very cold climate location (≥ CZ 6).
Image
The polyethylene ground cover in the crawl space is lapped up sides of piers to posts to provide a continuous air and vapor barrier
Image
The polyethylene ground cover in the crawlspace is continuous at interior posts and piers
Image
Image
Image
The preferred method for fire sprinkler connection to municipal water with a standalone, wet sprinkler system.
Image
The primary frontal dune will be lost to erosion during a 100-year flood because dune reservoir is less than 1,100 ft2
Image
The rails on these stairs were enclosed with siding, presenting a greater obstacle to the flow of flood water and contributing to the flood damage shown here.
Image
The reverse block method for seismic retrofit bracing of a cripple wall uses a 2x4 attached to the sill plate to provide a means to attach the plywood cripple wall sheathing to the sill plate
Image
The right window frame was pulled out of the wall because of inadequate window frame attachment during a hurricane.
Image
The risk of hydrostatic pressure differences in a flood is reduced when the interior grade of the crawlspace is higher or equal to the exterior grade.
