Sustainable construction is defined by the combination of techniques and products that not only increase the performance for the environment and the citizens, but also the quality of the buildings themselves. One of the first materials to be replaced in a green key is cement : the production of commercial products based on cement releases tons of CO2 into the atmosphere, contributing to the Earth's climate change.
Houses built with hay bales.
- Hay bales
An ancient method of construction challenges the research of new technologies: elements built from local materials, such as the hay bales of the fields, keep buildings isolated from hot and cold climates and represent a highly renewable resource . Usually used for the hollow spaces of building walls, they are able to replace products based on cement, plastics, stones or wood.
The completely green concrete carpet.
From "grass" (grass) and "concrete" (cement), Grasscrete is a flooring that integrates the use of cements or plastics with the growth of plants and herbs . Particularly present for outdoor flooring (including walkways and sidewalks), the benefit of grasscrete is twofold: it reduces the presence and the environmental impact of cement, while allowing the underlying flora to grow and drain rainwater in a natural way.
The earth that becomes a wall.
- Earth beating
A technology of antiquity can be a tool for green building: the "rammed earth" is nothing more than compressed earth and pressed in several phases to make walls as resistant as concrete . Unlike the past, however, today there are machines capable of pressurizing the earth, reducing the time and resources required to produce this material.
The wall that reduces transport costs.
From the inner fibers of the hemp plant is made of an ultra-resistant and sustainable material, which has characteristics very similar to those of cement but becomes lighter . Transport costs are reduced and it becomes easier to re-use the material during the demolition phase.
The new trend.
Bamboo is trendy, but in reality it is the material most used for millennia in the poorest areas of the world that use local natural resources to build buildings. The potential of this material is its strong resistance , light weight and above all its low environmental impact (it is in fact a continuously growing and easily renewable raw material).
