Off-Grid Rammed Earth House On Navajo Nation Catches The Wind

The architecture students of the <a href="http://inhabitat.com/design-build-bluff-sustainable-homes-for-people-who-need-them/" target="_blank">Design Build Bluff </a>program in southern Utah recently completed another house. This time grad students from the <a href="http://www.ucdenver.edu/academics/colleges/ArchitecturePlanning/Pages/default.aspx" target="_blank">University of Colorado Denver</a> were at the helm and completed a <a href="http://inhabitat.com/beautiful-rammed-earth-home-celebrates-colorado-nature/" target="_blank">rammed earth house</a> for Maxine Begay and her son. The <a href="http://www.designbuildbluff.org/project/dbb_2010_windcatcher.php" target="_blank">Windcatcher House</a>, which is totally off-grid and harvests all its water, features an innovative wind tower designed to capture the wind to cool the house.

Back in May 2010, 22 grad students from the University of Colorado Denver started planning Maxine Begay's new home and then started construction on it in September. This is the first semester a student group outside of the University of Utah designed and built a house on the Navajo Nation and the results were just as successful.

he Windcatcher House relies on local clay for its hand built compressed brick and rammed earth walls on the south and east sides of the home.

Thermal mass, shading and careful placement of windows help keep the home nice and cool during the hot, dry summers and soak up heat during the winters, which can get surprisingly cold.

The rest of the exterior is clad in your basic, inexpensive cement board and cleverly attached to the structure of the home.

The 1,100 sq foot, 2 bedroom home, located on Begay's family's homesite, also features a carport alongside it. The family doesn't actually have a car, but plans to use the carport as a barn for their animals.

Rainwater is collected off the carport's roof and pours into a trough and a irrigation system for the garden. As with all homes on the Navajo Nation, the Windcatcher House is totally off-grid - as there is no grid anywhere close enough to connected into.

The 30 ft wind tower is the most striking feature of the home and also an integral part of the design. Air moves across the open tower and travels down the shaft where rainwater soaked pads facilitate an evaporative cooling effect and naturally ventilate the entire home.

Traditional framing and a slab on grade foundation are combined with recycled, reclaimed and salvaged materials in this fantastic off-grid home in the desert.

We're certain that Maxine and her family are enjoying their new home. In total, the home cost $46,000, not including some materials that were donated.

Students from the University of Utah are already hard at work on the next DBB house near Bluff, Utah. This semester the Utah students will be working on a prefabricated home that will get installed later this spring.
