Our Focus

FOCUS

What we're digging into


Clean & Affordable Energy 

Supporting local, community based solutions to deliver affordability via energy efficiency and clean energy 

Prefabricated housing

Off-site, local prefabrication with cooperative ownership.  A path to housing that is affordable and Hawaiʻi-grown.

Distributed & diverse infrastructure

Water, wastewater, and resource systems as integrated, community-scale solutions instead of siloed, extractive utilities.

Systems & policy change

Supporting connections between regulators, utilities, innovators, and communities. Coalitions that strengthen implementation

APPROACH
Five Concepts Behind the 
Work

Hawaiʻi's culture of resourcefulness and innovation makes the islands the place to invest toward reshaping the essential living systems of modern life: housing, energy, water, and waste. The opportunity is here to create diverse, integrated, and locally controlled systems that are both affordable and sustainable.

01

Local circular economy

Replace extractive flows with value that stays in community hands.

02

Diversity of solutions

Move past one-size-fits-all toward many right answers for many diverse places

03

Integration of Systems

Buildings and utilities designed as connected parts of a single whole. 

04

Information as leverage

Use modern data tools and AI to put expertise back in the hands of people. 

05

Collaboration vs compliance

Shared vision unlocks innovation that rules bases systems cannot.
