We Build Green Cities is a group of building and planning professionals collaborating in Portland, Oregon. The mission is to share the ideas developed in Portland-area firms with the rest of the world, to foster the future development of sustainable cities, including resilient design and working with the local jurisdictions and codes.

Join us to learn more about the local and global initiatives of We Build Green Cities, and gain insight into how to implement these concepts using the Kashiwa-no-ha project in Japan as a case study.

Kashiwa-no-ha Smart City pioneered a new urban planning approach resulting in certification as the world’s largest LEED® Neighborhood Development Plan Platinum smart city. Large-scale sustainable living is reinforced through central energy management; energy conservation, creation and storage; local food production; and low-carbon transportation. Active and vital streets connect and energize the civic realm, support efficient resource use and build social cohesion as demonstrated by transforming a stormwater detention facility into a civic commons. Innovations respond to the Tohoku earthquake, tsunami, and Fukushima Power Plant disaster. Community behavior supports this strategy. Kashiwa-no-ha includes battery storage, an aerobic digester, connected buildings sharing energy and power, reducing peak demand and providing resources until power and water are restored. Through smart city placemaking, from policy to urban design, Kashiwa-no-ha is the best example of a technologically integrated, advanced mixed-use development with neighborhood facilities supporting multiple generations, lifestyles and uses for a resilient community.
