Casa Adelante 2060 Folsom, San Francisco | Mithun with Y.A. Studio
In San Francisco’s Mission District, where 47% of the city’s households are housing-cost burdened, Casa Adelante provides 127 households with permanently affordable housing at no more than one-third of their income. The project takes advantage of its walkable and transit-rich site to bolster social equity and strive for a low-carbon future. Through its massing, the project increases the south-facing perimeter to create the most housing and provides compelling park views for the majority of the building’s units. The team also reimagined a narrow fire easement between the site and the adjacent park to create a pedestrian paseo that delivers much-needed public outdoor space and a permeable area that boosts stormwater management and the region’s biohabitat.

Confluence Park, San Antonio | Lake|Flato Architects + Matsys
Along the bank of the San Antonio River, Confluence Park is a living laboratory designed to broaden visitors’ understanding of south Texas ecotypes and the impact of urban development on local watersheds. A destination for learning and recreation, the park is part of the country’s largest environmental restoration project and an accessible gateway to outdoor activity. The design reflects the idea of confluence—the park is situated at the junction of the San Antonio River and San Pedro Creek. Grand gestures such as the park’s shaped lands represent the convergence of ecotypes, while the central pavilion’s concrete petal structures draw inspiration from plants that funnel rainwater to their roots.

DPR Sacramento Zero Net Energy Office, Sacramento | SmithGroup
For its new headquarters in Sacramento, DPR Construction envisioned a sustainable work environment that would foster a greater sense of collaboration among its employees and would have strong ties to both nature and the surrounding community. The net zero energy project includes the renovation of an almost 27,000-square-foot building originally constructed in 1940 and a 5,600-square-foot addition built entirely with cross-laminated timber. As a compelling new addition to “The City of Trees,” the office is filled with biophilic design elements, a highlight of which is a seed wall that upends the concept of a living wall. It contains dormant seeds instead of live plants, including a selection of native grassland species that are vital to more than 90% of California’s wildlife. Read more on this project.

Harvard University Science and Engineering Complex, Boston | Behnisch Architekten
Among the healthiest and most energy-efficient laboratory buildings in the world, Harvard’s Science and Engineering Complex (SEC) helps shift the typology toward environmental stewardship. It sets a new standard for Harvard and highlights its mission to shape a more sustainable university community and planet. Designed to reflect the leading research taking place inside, the complex also connects users to one another in the spirit of collaboration. It was built just over the bridge from Harvard’s Cambridge campus in Lower Allston, one of 23 neighborhoods that make up the City of Boston. The goal was to create a new sustainably built home for the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) where a robust culture of collaboration and interdisciplinary work could be fostered. The SEC site is also a connector that links the neighborhood and Boston’s park system. Read more on this project. Photo: Brad Feinknopf
John W. Olver Transit Center, Greenfield, Mass. | Charles Rose Architects
The first net zero energy transit center constructed in the United States, the John W. Olver Transit Center is a vital intermodal hub that has introduced high-performance design to Massachusetts. The project, a depot for bus lines, Amtrak, and an office for the county’s government, is testament to Franklin County’s commitment to sustainability and ethical design. Shaped by a continuous process of community engagement, the center’s design pays homage to the city of Greenfield’s past, relying on dark brick, copper, and locally sourced stone that allow it to slip seamlessly into the city’s stately downtown district. The center forges a new paradigm for historically energy-dependent structures of its kind and, in doing so, has generated positive economic impact while spurring sustainable urban revitalization.

RIDC Mill 19: Buildings A & B, Pittsburgh | MSR Design
A vital new addition to Pittsburgh’s post-industrial landscape, Mill 19 is a bold transformation of a former steel mill that now welcomes the sustainable future of advanced manufacturing. Within the decommissioned mill’s steel superstructure, multi-tenant, tech-focused buildings create tension between old and new, while the country’s largest single-slope bifacial glass photovoltaic array crowns the project. In addition to accelerating the city’s future, Mill 19 is a potent catalyst for the development of Hazelwood Green, Pittsburgh’s largest riverfront redevelopment project, which is being built on its final large-scale brownfield site.

Watershed, Seattle | Weber Thompson
As one of the few buildings enrolled in Seattle’s Living Building Pilot Program, this building looks to move beyond incremental changes to achieve a better environment. Watershed is a regenerative seven-story office building making a profound positive effect on Seattle’s waterways, which suffer from a significant stormwater runoff problem that is affecting wildlife. Through strategies such as a series of bioswales that step down the site’s hillside, the building cleans more than 400,000 gallons of highly polluted water before it drains into nearby Lake Union. Inside its lobby, which is open to the public, visitors and tenants are kept informed of Watershed’s high performance through a digital dashboard, regular reports, and tours.

Westwood Hills Nature Center, St. Louis Park, Minn. | HGA Architects and Engineers
A new interpretive and accessible gateway to nature for the city of St. Louis Park, Minnesota, the Westwood Hills Nature Center immerses visitors in the surrounding forest full of birdsong and gentle breezes. Its design draws inspiration from the site with an exterior skin that evokes tree bark and a combination of fiber cement panels and window assemblies that subdivide and branch, much like the surrounding trees. The result of a vital partnership that included the design team, civic leaders, exhibit design specialists, and educators, the center is a true teaching tool and a vibrant amenity shaped by the city’s forward-thinking climate action plan that strives to achieve net zero by 2040.
