More and more people, when choosing a way to build their house, opt for ecological alternatives with low environmental impact, made with earth, straw and recycled bottles, among other materials.
Buildings made in this way are not only more environmentally friendly, but also represent a cheaper option for many families who otherwise would not be able to afford their own home. Architects, civil engineers and environmentalists have pointed out that this type of construction, in turn, proves to be very resistant at the building level, and allows energy consumption to be reduced by generating good thermal insulation from both cold and heat.
That it be accepted and included as an authorized construction method is a legal and cultural challenge, since many people still have prejudices regarding these building methods. In this context, for example, the work of the architect Armando Gross, from the National University of Córdoba (Argentina) to have bioconstruction recognized as a space within the Architecture career, is worthy of mention.
In this same South American country, approval of adobe construction is spreading.
The most traditionally used construction method not only leads to deforestation, but also to high energy consumption to burn industrial furnaces that, in turn, emit a large volume of polluting gases.
These techniques, which in recent years have begun to be approved, stand out for being much more friendly to the environment and promise a sustainable way of accessing a home. Among the most outstanding are those that use adobe blocks or lightened earth; the construction of walls with bales of straw; the monolithic ones (such as formwork straw, rammed earth, superadobe); and those with frameworks, such as reeds or strips (quincha); among other.
This year, the city of Mar del Plata (in Buenos Aires) joined others that already have this normalization. Santa Rosa, Winifreda and Colonia Barón, in La Pampa; Bahía Blanca, Coronel Suárez, Tornquist and Ayacucho in Buenos Aires; Luis Beltrán, Bariloche, El Bolsón, San Martín de los Andes, in Río Negro; and El Hoyo in Chubut and Cachi, in Salta; continue the list.
In any case, as is known, in many of these places there is an ordinance, but it is not yet regulated, so it is not yet in force.
Rodolfo Rotondaro, a specialist in this type of construction who is also an adjunct professor at the University of Buenos Aires and a CONICET researcher, pointed out that this work arose: “Given the demand to build houses with environmental advantages that collaborate with achieving less pollution and a reduction of the greenhouse effect (generated by the manufacture of various conventional construction materials). And having lower costs, it is accessible to the middle and lower classes.”
And he adds: “We are beginning to manage a working group at the INTI (National Institute of Industrial Technology) to design IRAM standards for this type of construction.”
