To introduce the topic on sustainable materials and environmentally friendly, we must first talk about green building and green architecture, two disciplines that respond to the current situation of increasing pollution and environmental degradation. The green building uses environmentally friendly materials, non-polluting, trying to reduce as much as possible and limit the consumption of non-renewable energy, protecting the environment through energy savings and reducing the cost of operation and maintenance in order to amortize the cost in a short time installation.
The use of environmentally friendly materials, including certificates, and alternative energy sources are not sufficient to guarantee the quality of a sustainable project because it is necessary and important to consider aspects related to the impact on the environment and economic ones. Therefore, when we evaluate the suitability of a material, we must take into account the whole life cycle and the potential impact on every stage, from production to use to disposal, has on the environment. For this reason, even the non-renewable materials can be regarded as sustainable long as they have an efficient manufacturing process from the point of view of energy, with low emissions and durability superior to that of their renewable alternatives.
