Image
Use a truss joist header assembly as shown here to reduce thermal bridging in hot climate zones.
Image
Use copper or stainless steel mesh plus caulk or foam around holes in exterior walls or epoxy in cracks in concrete to keep out rodents and termites.
Image
Use flexible straps to secure large electronics equipment like computer monitors and microwave ovens during seismic events.
Image
Use plumbers metal strapping, wood blocking, and shelving brackets to secure a water heater in a corner to prevent tipping during an earthquake.

Image
Use strapping, wood blocking, and shelving brackets to secure a water heater to a straight wall to prevent tipping during an earthquake.
Image
Image
Using outdoor misters or spray fountains can cool the outside air before it enters the house
Image
Using roof and wall materials with a high Solar Reflectance Index (SRI) will reduce heat gains.
Image
Variation of maximum negative main wind force resisting system (MWFRS) pressures based on envelope procedures for low-rise buildings.
Image
Image
Vented crawlspace cripple wall has seismic retrofits – plywood is added on interior that fastens to extra blocking added at sill plate and connected to foundation with new anchor bolts
Image
Image
Vertical (buoyant) flood force; buoyancy forces are drastically reduced for open foundations (piles or piers).
Image
Vinyl and aluminum soffit panels can blow away in high winds if not properly connected.
Image
Wall assembly with non-combustible brick cladding and fire-resistant or retardant rigid insulation, sheathing, framing and cavity insulation.
Image
Wall assembly with non-combustible fiber cement cladding, metal hat-channel furring for air gap and fire-resistant or retardant rigid insulation, sheathing, framing and cavity insulation.
Image
Wall surfaces having high solar reflectance and high thermal emittance will remain cooler when exposed to direct sunlight.
Image
Image
Warm air that leaks into the attic through unsealed light fixtures or other bypasses can melt snow on the roof leading to ice dam formation.
Image
Water depth versus wave height, and water depth versus breaking wave force against, a vertical wall.
Image
Image
Water management detail for a solar panel rack mounting block installed in rigid foam that was installed over an existing roof
Image
Image
Water management details for a roof drain installed along with rigid foam on a flat roof
Image
Wave scour at a single vertical foundation member (pile), with and without underlying scour-resistant stratum.
Image
Image
When averaged over several years, more fatalities are caused by extreme heat than by any other weather-related hazard
Image
When flood waters reach living areas, the resulting mold and contamination can greatly increase clean up time and costs.
Image
When installing fasteners in roof sheathing, common mistakes include using the wrong size fasteners, missing the framing members, overdriving nails, and using too many or too few fasteners.
Image
When no automatic gas shutoff valve is installed at the meter, the gas valve can be shut off using a wrench
Image
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 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

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
Whole-house fans or wind-driven cross ventilation can be used to draw air across thermal mass for a night flush strategy
