Bioconstruction is a sustainable construction approach that seeks to use natural and renewable materials, as well as environmentally friendly construction techniques. Its objective is to create healthy buildings, efficient in energy consumption and with minimal impact on the environment.
One of the fundamental pillars of bioconstruction is the use of vernacular materials. These materials are those that are found naturally in the region or geographic area where it is built, and that have been traditionally used by local communities in their buildings.
Some examples of vernacular materials are wood, bamboo, earth, straw, cane, stone, among others. The use of vernacular materials in bioconstruction has several advantages. First, these materials are abundant and available locally, reducing the need for transportation and the associated carbon footprint. In addition, by using natural materials, the use of toxic chemicals present in some conventional materials is avoided, such as volatile organic compounds (VOCs) that emanate from synthetic materials.
Another important advantage of vernacular materials is their ability to regulate the interior climate of buildings. For example, the raw earth used in techniques such as adobe or rammed earth has thermoregulatory properties, which means that it helps maintain a comfortable temperature inside, both in hot and cold climates. In addition, these materials usually have good sound insulation capacity.
The use of vernacular materials in bioconstruction also promotes the preservation of traditional techniques and knowledge of local communities. These techniques have been developed over generations, adapting to the climatic and cultural conditions of each place. By using these materials and techniques, cultural diversity is valued and promoted and sustainable development is encouraged from a
local perspective.
Bioconstruction and the use of vernacular materials go hand in hand to promote more sustainable and environmentally friendly construction. These practices seek to take advantage of the natural resources available in each region, minimizing the environmental impact and creating healthy and comfortable spaces for people.
