Dear Cool House Tour Friends, Welcome to our 16th Annual Austin Cool House Tour. If tradition holds, it will be hot on June 3, so duck into all of these 10 cool homes. You’ll see the best of green building in a variety of styles and sizes, learn about passive solar design, thoughtful construction techniques and the latest technologies. Energy efficiency meets beauty and comfort. We urge you to talk to the homeowners and professionals who make this tour possible and to use their insight and information to create your own energy efficient projects. Every year we notice trends in design and construction. Large scale urban rainwater collection has been gaining momentum and the 2010-2011 drought brought attention to the value of collecting what little rain does fall. The physics of natural air flow and the simple fact that hot air rises is a factor in several of this year’s homes, highlighting the cooling power of cross and stack ventilation. The Texas Solar Energy Society is honored to once again partner with Austin Energy Green Building, the winner of the 2011 United Nations Scroll of Honour Award for promoting sustainable and energy efficient design and building techniques. Started in 1991, AEGB has just celebrated the completion of “The 10,000 Rated Home.” Enjoy the tour, use our first ever phone app, stay cool, and remember that ultimately there is money and resources to be saved by designing and building sustainably. Best regards, Natalie Marquis - TXSES Executive Director Lucy Stolzenburg-TXSES Outreach and Development

Hill Country EcoBuilders
Lloyd Lee | www.hcecobuilders.com | 512-970-1401 9717 Peakridge Drive Austin, TX 78737 To reduce their dependence on fossil fuels, the owners pursued a plan emphasizing strong passive design. Proper home orientation on this rural lot creates cross ventilation, natural daylighting, and shading in summer and heat gain in winter. Despite having a public water tap available at the street, they opted for a whole house rainwater system. A geothermal heat pump provides efficient heating and cooling with supplemental hot water; a solar array provides energy from the sun. Directions- From the Y in Oak Hill (W290 and 71W), continue west on W 290 3.2 mi, (L) on Ledgestone Terrace for .5 mi., (R) on Peakridge
Green Features: • House thoughtfully designed for passive heating, cooling and daylighting • Dogtrot design captures prevailing breezes and separates the garage from the house to prevent hydrocarbon gassing • Large covered porch extends the living area • Appropriate overhangs minimize heat gain in summer and maximize heat gain in winter • Windows on the south and clerestory windows on the north ensure abundant daylighting • Geothermal HVAC • 3.3 kW solar system • Dedicated fresh air intake system, energy recovery ventilator dehumidifies incoming air • Energy efficient induction cooktop • 20,000 gallon rainwater system for interior and exterior use • Plumbed for future greywater irrigation system • Tree protection during construction and landscaped with native plantings

This lot was so steep it was once deemed unbuildable. The design of this home takes full advantage of the prevailing breezes, spectacular views, and the owners’ desire to remain in the neighborhood they call home. The house hugs the rocky ridge and steep slope, providing a top floor to accommodate the owners’ plan to ‘age in place’, while the downstairs is a space for family visits. The best compliment to this home’s energy efficient design? In the teeth of the brutal 2011 summer, this house was the venue for a fundraiser that was cool and comfortable. The average monthly utility bill over one year was $127.
Directions - From Mopac, west on Far West 2.1 mi., (R) where Far West becomes Ladera Norte for .6 mi., (R) at Valburn

Acknowledgements As with all volunteer events, there are so many people to thank and the fear always lingers that someone will be forgotten. First and foremost, thank you to the homeowners who will graciously open their houses to literally hundreds of tour goers on June 3. Their professional guides, the architects, designers and builders who navigated the Austin Energy Green Building rating process, deserve our thanks for their commitment to sustainable building and design practices. The stalwart volunteer selection committee, fueled by Gary Citronâ€™s baking expertise and transported in Nathan Doxeyâ€™s 1986 Vanagon, included Mary McLeod, Richard Burns, Joe Bennett and Yvonne Hansen (veteran of all 16 tours). The AEGB team keeping everyone honest was Jessica Galloway and Bryan Bomer. Brenda de la Garza and Jorge Alvarado were invaluable with their oversight of the guidebook, designed and executed by Margaret Andersen. And finally on tour day, there will be over 70 volunteers, most of whom are veterans of past tours, who will greet you, ask you to flash your guidebook/ticket, and once more remind you to take off your shoes or don those blue booties.
