The Tarrytown Bungalow, designed by Barley & Pfeiffer Architects and built by Ray Tonjes in April 2009, achieved the Five Star rating by the Austin Energy Green Building program. Located near downtown Austin, the house is oriented to capture prevailing breezes, and a 30,000-gallon rainwater collection cistern under the garage is used for landscape irrigation.
The screened porch captures southeasterly breezes that are then drawn through the home and exhausted at a skylight over the second-floor catwalk and the windows in the stairwell.
The large windows with deep roof overhangs were sized to provide summer shading yet allow for ample daylighting and natural winter heating from the sun.
The home’s exterior wall sheathing is comprised of three layers: rigid OSB, a commercial-grade building wrap, and ¾-inch continuous insulation board. In addition, a 9.66-kW grid-tied solar PV system generates nearly as much electricity as the house consumes.
