    The LEED-Platinum dwelling gets its high-performance power from solar energy, greywater recovery, and ultra-efficient insulation. Uni-Solar’s low-profile Flex-Lite PV panels were installed between the ribs of the standing-seam metal roof for superior storm resistance.

    The kitchen cabinet boxes are made of locally sourced, urea-formaldehyde free plywood and all doors, drawer heads, and shelves are made of reclaimed materials that builder Josh Wynne salvaged from a local sawmill.

    The Power Haus' toilets are Kohler dual-flush units and operate on recycled greywater. Hot water is supplied through two 98.2% efficient Eternal hybrid gas hot water models and plumbing is looped to allow for on-demand hot water.

    Power Haus has two under-slab waste piping systems: one for greywater from the sinks, laundry, and showers and ones for blackwater from toilet waste. The greywater runs into a Brac 250-gallon recovery system and is filtered for re-use as toilet water. Outside, all of the roof’s runoff is captured in 8-inch Galvalume gutters across the eaves and gravity-fed underground to a remote 6,000-gallon cistern (shown) where it is used to fill horse-watering troughs and for irrigation.

The serene setting of the Power Haus belies its hardworking and highly efficient infrastructure, including a 250-gallon greywater recovery system, a wind-resistant 14.2-kW PV array, and carefully calibrated and installed HVAC components. Thanks to an ultra-tight insulation package including rigorous air sealing and 5 inches of closed-cell spray foam, the home is so efficient it garnered a -22 HERS rating, the lowest ever recorded by Energy Star.

With 30% fly-ash concrete CMU foundation and walls, low-E impact-rated windows, and a standing-seam metal roof, the coastal home is engineered to withstand up to 150-mph winds. Polished concrete floors; clay walls over mold-resistant drywall; native cypress doors, trim, cabinets, and roof framing; and tough but beautiful FSC-certified Massandaruba wood decks offer exceptional performance against the elements while enhancing the contemporary Florida Cracker vernacular.

The home is wide open to the west to capture sea breezes and expansive views of the nearby hardwood swamp and the green field beyond, where the homeowner makes the 0.1-mile commute to his job as a polo player.
