Local vs. certified materials: Which is really more environmentally friendly?
Introduction
Sustainability in architecture is a broad concept that goes beyond the selection of materials with international certifications. Many projects are looking for ways to reduce their environmental impact, but is it really better to opt for certified materials or is it more environmentally friendly to choose those that come from the same region where they are built? In this article we analyze the advantages and disadvantages of both options to determine which is the best alternative.
What does it really mean to be green?
Being “green” in construction does not only mean using materials that have sustainability seals. It also means considering the entire life cycle of the material, from its extraction to its final disposal, as well as its impact on transportation, the energy used in its manufacture and its compatibility with the natural environment.
Local materials: advantages and disadvantages
Carbon footprint reduction
Transporting materials from distant locations involves considerable expenditure of fossil fuels, which increases CO2 emissions. Using local materials significantly reduces this impact.
Adaptation to the environment
Local materials are often better adapted to the climatic and geographic conditions of the region, which improves the thermal efficiency and durability of buildings.
Availability and costs
In some cases, local materials may be more accessible and cheaper, although this depends on demand and availability in the region.
Certified materials: advantages and disadvantages
Guarantee of sustainability
Certifications ensure that materials meet certain environmental standards, which can generate greater confidence in their positive impact.
Regulations and standards
In many countries, certified materials facilitate the approval of projects under sustainable construction standards.
Costs and accessibility
Certified materials are usually more expensive due to the certification process and transportation logistics.
Conclusion: Is it time to rethink our sustainable construction criteria?
Both options have advantages and disadvantages, but the key is to evaluate each case according to the specific context of the project. An internationally certified material is not always the best option, nor do local materials alone guarantee sustainability. It is time to rethink our selection criteria to prioritize the balance between environmental impact, efficiency and economic viability.
Frequently Asked Questions (FAQs)
- Are certified materials always more environmentally friendly than local materials?
Not necessarily. Although they have sustainability seals, their transportation and production can generate a high carbon footprint. - How do you know if a local material is really sustainable?
Its origin, the impact of its extraction and processing, and its durability in construction must be analyzed. - What is the main benefit of using local materials?
Reduced carbon footprint due to the reduced need for transportation. - Do material certifications guarantee sustainable construction?
Not always. They are a good indicator, but should be evaluated along with other factors such as building design and efficiency of use. - What is the best strategy for choosing environmentally friendly materials?
Conduct a life cycle analysis, compare carbon footprint and assess its adaptability to the project environment.
