Image
Vertical (buoyant) flood force; buoyancy forces are drastically reduced for open foundations (piles or piers).
Image
Vertical service shafts and trash chutes are isolated from corridors in multistory buildings by locating them within the vestibules
Image
Vertical side-shading, such as these side fins, can provide effective summertime shading for north-facing windows, but are generally not recommended for other orientations due to their marginal performance and restricted views
Image
Vertical trellises and tall shrubs provide very effective shading to the east-facing wall of this home.
Image
Image
VESA mounts can be used to secure televisions to the wall and prevent damage during seismic events
Image
View-preserving interior solar screens such as these help reduce glare and solar heat gain while maintaining view to the outside

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 controls operate the windows and fans allowing homeowners to capture prevailing breezes.
Image
Image
Wall grilles installed high and low on the wall of the heat pump water heater closet allow passive ventilation of a small room with warmer air coming in at the top and cooler exhaust air exiting at the bottom of the wall
Image
Image
Image
Wall space is provided next to the electrical panel in the garage for the home’s photovoltaics system.

Image
Walls in cold climates with a Class 3 vapor retarder (latex paint) and a vapor-open continuous insulation like mineral wool allow drying to the interior or the exterior
Image
Walls in cold climates with a polyethylene vapor barrier interior of the wall cavity should have either no exterior insulation or a vapor-open continuous insulation like mineral wool that allows drying to the exterior
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.
