Image
This fastener schedule for metal panel siding shows denser spacing for the end panels to resist stronger wind pressures. Some manufacturers specify that panels be installed with the prevailing wind - in this example wind direction is right to left.
Image
This FEMA flyer recommends using the stairs in case of fire; automated smoke control systems are often designed to minimize smoke in the egress path during a fire or smoke emergency.
Image

Image
This fully packaged/skid-mounted central heat pump water heating system was shipped to the building on a truck and craned into location
Image
This fully specified central heat pump water heating system has four individual outdoor heat pump units plumbed in parallel to indoor storage tanks
Image
This garage door was blown from its track by positive wind pressure and adhesive-set roof tiles were pulled up but the windows were protected by roll-up shutters from the 140 to 160 mph hurricane winds.
Image
This gasoline tank collapsed due to pressure from flood waters during Hurricane Katrina, 2005, Biloxi, MS.
Image
This gasoline tank was lifted out of the ground by the buoyant forces of flood waters in the Iowa flood of 2008.
Image
This Habitat for Humanity builder ordered roof trusses with a 2-foot by 2-foot notch next to the center post then lined the cutout with rigid foam to form an insulated central duct chase to bring the heating and cooling ducts within the conditioned space.
Image
This heat pump water heater has been fitted with ducts to exhaust its waste cooling into the occupied living area
Image
This Heat Pump Water Heater has Pipe insulation installed on the hot water line (on left) and on the cold water line (on right)
Image
This heat pump water heater is centrally located in a laundry room so that all hot water uses are less than 15 feet from the tank.
Image
This Heat Pump Water Heater is Sitting on an Insulation Pad to Reduces Heat Losses
Image
This heated garage plenum is insulated along the bottom and sides, and the insulation is fully aligned with an air barrier. The insulation at the bottom of the plenum space meets IECC insulation requirements.
Image
This heated garage plenum space is insulated along its top, bottom and sides, and the insulation at the top of the plenum meets IECC requirements. The insulation along the top and sides is fully aligned with an air barrier.
Image
This high-thermal-mass home uses concrete construction for disaster resistance as well as to naturally regulate temperatures inside the house
Image
This highly efficient 1,290-ft2 home by Habitat for Humanity of South Sarasota County, Florida, is built to the requirements of the U.S. Department of Energy (DOE) Zero Energy Ready Home program and has low utility bills of about $72 per month.
Image
Image
This home bears a DOE Zero Energy Ready Home label on its front window next to the ENERGY STAR window label.
Image
This home constructed in a V Zone in Bolivar Peninsula, Texas, had the bottom beam of the lowest floor at the BFE (dashed line) but the estimated wave crest during Hurricane Ike was 3 to 4 feet higher (solid line).
Image
This home has a cost-saving shallow frost-protected foundation that uses rigid foam laid vertically at the base of the 16-inch-deep footers to protect the foundation from frost damage.
Image
This home has defensible space around it, with a vegetation-free zone that helped the house survive a surrounding wildfire.
Image
This home has heat loss through the roof, leading to ice dam formation and structural issues during winter months.
Image
This home has hurricane straps at every roof truss to attach the roof to the exterior wall top plate for increased resistance to wind uplift (Source: David Weekly Homes).
Image
This home is covered with coated sheathing. Wall portions that will be covered with stone have a dimple plastic moisture barrier and metal lathe that is being covered with plaster.
Image
This home is equipped with an ultra-efficient (COP 5.7) ground source heat pump, which also provides domestic hot water that is stored in a tank.
Image
This home is equipped with two electric vehicle chargers conveniently located in the garage.
Image
This home is framed with post-and-beam construction and 7-inch wall cavities that will be filled with blown-in fiberglass insulation.
Image
This home is heated with in-floor hydronic radiant heating tubes that were installed on top of the R-20 rigid foam under-slab insulation.
Image
This home is piped with an insulated hot water recirculation loop that speeds hot water to each fixture while helping to reduce water waste.
Image
This home on a mountain top in San Ramon, California, has four 10,000-gallon stormwater/greywater cisterns (two are visible at top left) for fire suppression as well as five 10,000-gallon rainwater storage tanks for indoor potable water.

Image
This home uses light-colored standard paints and finishes on siding and roofing materials to reduce cooling loads without adding material cost.
Image
Image
This home was designed with continuous roof vents and few roof penetrations, allowing more room for the solar shingles that integrate with the asphalt shingles installed to meet IBHS Fortified Roof criteria for increased resistance to high winds and rain
Image
This home was elevated above the Design Flood Elevation and the pre-existing first story became the second story.
Image
