Eco Factor: Home built using organic materials, and rainwater is reused and recycled. After you go through the pictures, I don’t think there is any need to explain that why the structure is named the Leaf House. Perfectly suited for the region and climate, this aesthetically wonderful structure stands firmly at Rio de Janeiro to shield you from the scorching heat of sun. The inspiration was gathered from Brazil’s Indian architecture and put into reality without the slightest of mistakes. The verandas and in-between open spaces let trade winds rising from the sea to ventilate through building and provide passive cooling. That means you don’t need an air conditioner to cool down. 
The creators of this eco wonder, Mareines +Patalano, did a quite good job to maintain the harmony between man and nature. Most of the building is built of organic material and includes a design to harvest rainwater for re-use. 
The Dark Side: Although, aesthetically, the building deserves appreciation, there are still scopes of utilizing natural resources for energy like including solar panels, wind turbines. Trendhunter via: WorldArchitectureNews
