The Power Haus was built by Florida-based builder Josh Wynne Construction. Located in Sarasota, Florida, the house has achieved a minus 22 HERS index, the lowest HERS rating on record in the US, and is producing more energy than it consumes on a yearly basis.

The Power Haus by Josh Wynne Construction:

“Power Haus was designed to exceed every standard in green construction today while maintaining the clients’ desired aesthetic and comfort requirements. It is a shining example of the level of performance and sustainability that can be achieved while maintaining a high standard of quality and comfort.

Power Haus received a minus 22 HERS index, the lowest ever recorded by Energy Star and the DOE Builder’s Challenge. It is the highest scoring LEED for Homes Platinum ever certified (pending verification). Power Haus is also at the top of the FGBC standard and NAHB’s National Green Building Standard.

Design plays a huge part in Power Haus’ performance and livability. Passive ventilation, passive cooling and passive lighting go hand in hand with the desired ability to open the home to the expansive views of the hardwood swamp upon which the home is situated. In many ways, it is difficult to determine the line between indoors and out. That is quite difficult to accomplish in the hot, moist climate of the central west coast of Florida. Since few materials are up to the challenge presented by this climate, product specification and construction techniques were very important. Polished concrete floors, clay walls over mold resistant drywall, native cypress timbers used for doors, trim, cabinets and roof framing all lend to the ‘Contemporary Florida Cracker’ vernacular while offering stellar performance against the elements.

Power Haus is a beautiful home that compromises nothing while managing to shatter the ceilings perceived to exist in luxury green home building.”
