A Seattle family tasked Atmosphere Design Build with creating a sustainable dwelling in Nevada City, California, the matriarch's hometown and a historic mining community. The firm's material-driven approach channels the pioneer spirit of the gold rush, without compromising comfort or high-efficiency standards.

At a net-zero home in San Francisco, the house's green roof is more of a brown roof: a desert-like array of native and non-native succulents that require minimal irrigation. The soil area is maintained with motorcycle tires (including one from a Harley hog), which control erosion. Composting takes place here as well.

Metal shingles cut from scraps of sheet metal mix with new material as well as odds and ends, such as a road sign Baker bought at the Alameda Flea market. Baker designed stainless steel clips that allow any tile to be easily moved or replaced without the use of tools. Planter box panels add  functionality to the facade and can be swapped out or relocated throughout the year.

NET was founded by renowned architect Alejandro Sticotti in 1990. The firm prefers to use South American hardwoods that, in addition to being durable, anchor their products in their Argentine origins. For instance, the Silla ska chair (seen here) is made from lenga, a patagonian wood that resembles American cherry. The satin black floor lamp is also from NET.

Bullitt Center (Seattle, Washington: 2013)

Denis Hayes, chief executive of the Bullitt Foundation, said that if the Bullit Center, his organization’s ambitious experiment in creating a sustainable and “living” office building, is still the greenest space of its kind in a decade, it will have been a failure. That’s not bragging, that’s merely an insight into the scope and ambition of this revolutionary structure, a testing ground for water and energy self sufficiency (via rainwater collection, composting, and a large solar array) aiming to be a case study for radical change in how we build. Based on stats released on Earth Day in April, the building’s first anniversary, the structure is currently using 75 percent less energy than a similar structure and is on its way to a net zero energy certification.

The top floor of the two-story, 1,614-square-foot abode barely pokes above the rocky hillside it’s built into. Sliding glass walls on two sides of the main living space open to expansive cantilevered decks showcasing the bucolic landscape.

Tsai Design was able to double the home’s footprint via a rear addition that includes two bedrooms and two bathrooms. (The original home was 645 square feet, and the extension added 614 square feet.) The firm then introduced plenty of natural light and three separate exterior decks that add up to 270 square feet of outdoor space.

Accessed by a ladder with alternating treads, the sleeping loft features custom casework by Kevin P. Clarke Custom Woodwork that holds Kid Robot figurines, Hopi baskets, and an iPhone gramophone by Lawrence LaBianca. Lights by Pablo Designs are perched atop a bed that Baker designed. Peeking out from under the rug (made by Baker’s mother, Emilie) is a salvaged maple floor, which was finished with VOC-free flaxseed oil.

Sticotti cites a mixture of design inspiration from Japan, Scandinavia, and European designers who emigrated to the Unites States. A simplicity and honest expression of materials is evident in this coatrack made from peteribí and lapacho, both South American woods.

Designed and prototyped by David Baker Architects, the building’s siding was made from salvaged maple flooring left over from another project. Inspired by the Japanese and Finnish practice of finishing exterior wood by charring, Baker used a roofing torch to char the boards and screwed them into vertical cedar battens.

The compact 712-square-foot cottage sits on top of a 430-square-foot workshop, where Baker’s firm prototypes and produces custom furnishings for his practice. “Not only is there room for more density on most residential blocks in San Francisco, but, if thoughtfully conceived, it also enriches our communities and makes our cities more resilient,” Baker says.

Chicago Net Positive Home (Kipnis Architecture + Planning)

The home manages a net zero rating thanks to a grid of solar panels mounted on the garage, which generates enough power to take care of the home’s electricity needs and charge an electric car and hot tub on the roof.

Architect Nathan Kipnis’ plans utilized super-tight construction, skylights, and carefully calibrated air flow to increase natural light and ventilation while lowering energy usage. Landscape designer Julia Bunn enlivened the 400-square-foot roof with a green rooftop garden.

As the roof had to be clear for fire department access, Baker developed a cantilevered frame for double-sided solar collectors that is elevated a few feet above the rooftop. The frame’s tilted configuration actually allows the panels to collect more energy than traditional flat designs. Seen here before the panels were installed, the frame holds sixteen photovoltaic collectors and is a 3KV system—large enough to generate more energy than the house requires in a single year.

Outfitted with shelves by EZ Shelving and a generic tool chest, the kitchen’s galvanized steel integrated counter and sink was designed by Baker and fabricated by DeFauw Design + Fabrication. A vintage pair of Norman Cherner’s Plycraft chairs and an A Chair by sustainable furniture-maker David Colwell surround a table by Pacassa Studios, which mounted a custom top on a Herman Miller Eames base. All appliances are electric, including heat-radiating panels, a combo washer-dryer unit, and an induction stove.

Sticotti collaborates closely with Tovo in the design and production of their pieces; six to seven designers and administrators work in NET's offices while an equal number of employees work in a separate workshop, also in Buenos Aires. The wall-mounted library seen here is made from cedar and platinum peteribí.

Estadio Nacional de Brasilia Mané Garrincha (Brasilia, Brazil: 2013)

Named after a national soccer icon and located in the center of Niemeyer’s monumental planned city, Estadio Nacional de Brasilia Mané Garrincha could not have been a higher profile project. Castro Mello Arquitetos rose to the challenge with the world’s first net-zero energy stadium, an impressive feat of public design and engineering considering the massive energy spikes during big events. A combination of rainwater collection, solar arrays, shading, and a photocatalytic membrane that breaks down pollution makes this a key legacy of the recent surge in Brazilian stadium construction. By itself, the soccer field generates more solar energy than 11 of the competing nations.
