Researchers at the Autonomous University of Chiapas (AUC) created economic green roofs, which keep the interior of the houses 17 degrees cooler than the temperature outside.
The green roof is a garden that is placed on roofs and represent many advantages, as they are protective against solar radiation, and, as is the wider area of the house exposed to the sun and the roofs of reinforced concrete focus heat, these mulches managed to reduce the temperature 17 degrees inside the house in relation to the temperature outside.
In addition, this roof can replace the waterproofing, preventing an annual expenditure in that area. Besides being aesthetically if given proper care, it helps reduce the phenomenon known as heat islands in the cities. It also slows water runoff, helping to prevent flooding in urban centers and recovers rainwater.
Among the contributions of this innovation is a system using recycled PET to trap the roots and prevent them from breaking the ceilings. Plastic bottles also serve to raise the substrate (ground) and have the advantage that they are lightweight.
