The standard North American home (pictured above) is horrible inefficient and quite bad for the environment. As the climate crisis conies to worsen we need to change the way we provide shelter for people: and that’s exactly what Phoenix, Arizona did. Arizona is experience such extreme heat that everyday objects are melting and car tires explode, sometimes the airport can’t function either. This led the City of Phoenix to launch a competition for making the most affordable and environmentally friendly home.
The winning home building plan is available for free online from the city, meaning you can download a home.
The winner of the contest, Marlene Imirzian & Associates Architects, went even lower. The studio’s affordable, three-bedroom home, dubbed HOME nz, has an impressive HERS rating of zero. A $100,000 prize went to Imirzian’s firm, and the design is now available for widespread use; the City of Phoenix has made the construction plans for HOME nz available for free to encourage the public to build more eco-friendly homes. “The city of Phoenix has a very visionary sustainability director and department who are looking for leadership for built work in the Phoenix area,” says Imirzian. “[The] goal was to show how simple moves could result in significant [environmental] changes.”
Since Phoenix’s dry, sun-bleached environment involves extreme heat, the design incorporates high-performance glass, which reduces heat transmission from outside, and retractable fabric screens for greater shade and passive cooling without the help of an AC unit. But HOME nz is a useful and applicable model no matter the climate. “If the volume performs well in terms of the separation of the interior and exterior then no matter where you build your house, it will be managed optimally by what you’re surrounding the house with,” notes Imirzian. “It would do just as well in a very cold climate or [a place] where you need conditioning or heating.”
