Water, food security and land stewardship are just as important as energy independence for this Texas ranch house, a winner in this year's Green Home of the Year Awards.resilient_ranch_green_builder.jpg2015 Green Builder Best Resilient Design

FAMILY AND COMMUNITY are the focus of this ranch, creating a space where the homeowners could age in place surrounded by family, food and the Texas countryside. Nestled on 100 acres in Texas Hill Country, this artist’s compound is a colorful gem of self-sufficient living and connection with nature.

In the past few years, Texas has been plagued with drought and wildfire; the homeowners built this passive solar home in response to the changing landscape. A preliminary Wildfire Defense assessment was incorporated into the building site to minimize risk of loss.

PROJECT STATS

NAME: Rainwater Ranch, Burnet, TX
BUILDER: Native
ARCHITECT/DESIGNER: Stephen Colley, Stephen Colley Architecture

An abundant one-acre garden and orchard are watered solely by a 30,000 gallon rainwater collection tank, which is also used to water Longhorn cattle and other livestock. An additional 40,000 tank provides 100 percent of the family’s domestic water. This solar-powered compound is complete with a battery backup system to support the energy needs for both the main house and detached living quarters.

The building envelope integrates 2 x 6 advanced framing, full fill spray foam insulation and ZIP System into an exceptionally energy efficient yet affordable home. Whole-home air filtration and a high-efficiency Carrier Infinity variable-speed heat pump provide a comfortable and healthy home environment. No-VOC paints and stains were used throughout.

Large overhangs and screened porches reduce exposure to the intense Texas heat and provide the family with additional living space. Handcrafted handrails, made by local blacksmiths, incorporate local materials.

This home has currently achieved a 10 HERS rating. The homeowners are already planning an expansion of the 8.7-kW solar array, with the ultimate goal of net-zero energy.
