Accessible Sustainable Solutions


Our design library has open-source designs shared by people and organizations worldwide. Each design is downloadable for anyone to use. So what makes appropriate technologies?

Smart design

The solution is designed so that basic skills are sufficient to create the technology. The designs use local skills and materials available to maintain the technology.

Low Investment

Appropriate Technology requires little capital investment by using naturally abundant, recycled, and low-cost materials to create jobs and grow resilient, local economies.


Decentralized systems avoid expensive infrastructure and reduce energy inefficiencies with transporting goods & services from central locations.

Energy Efficient

Appropriate Technologies rely on renewable energy like solar, water or wind power which are then reused and recycled in closed-loop systems that sustain ecosystems.
