The Madrid 'Air Tree'

Spain (TGW) – Madrid will build a huge structure called an “Air Tree” or “Eco Boulevard de Vallecas”, Spain announced recently.

The Tree was created by Urban Ecosystem to be a social center and to improve the surrounding environment.

The tree produces its own energy using its many solar panels, and excess energy is sold to local power companies. The tree also produces oxygen – hence its name.

Also, the building is efficient; the materials are lightweight, recyclable, and made from recycled materials.

In more practical terms, the building is a social center where temperatures are 8-10 degrees Celsius cooler.
