This house built at Playa Carate, Peninsula de Osa, Costa Rica, created by Robles Arquitectos is 100% self-sufficient. The house uses water from the forest, which also serves as a power source thanks to two low-impact hydroelectric turbines that generate 800kWh. Photovoltaic Solar panels on the roof provide up to 10,800kWh of electricity, whilst additional solar thermal panels heat up the water.
The house is so isolated from civilization that it has no access to public power cables, sanitation, or water.
Everything in the house has been designed to be energy efficient and easy to maintain, and all the building materials were tested in order to gauge their impact on the environment.1
