Resumen
Los Sistemas de Calificación de Edificios Ecológicos (GBRS) a menudo pasan por alto el carbono incorporado en la construcción. Este estudio mapea los GBRS, encontrando que la mayoría prioriza el carbono operativo, lo que dificulta los esfuerzos de descarbonización de por vida.
Área de la Ciencia:
- Ciencias Ambientales
- Arquitectura Sostenible
- Rendimiento de Edificios
Sus antecedentes:
- La industria de la construcción contribuye significativamente a las emisiones globales de carbono.
- Los Sistemas de Calificación de Edificios Ecológicos (GBRS) tienen como objetivo promover la sostenibilidad, pero abordan de manera desigual el carbono de por vida.
- A menudo se prioriza el carbono operativo sobre el carbono incorporado en los GBRS existentes.
Objetivo del estudio:
- Realizar un mapeo estandarizado del carbono del ciclo de vida de los criterios de los GBRS.
- Evaluar la capacidad de los GBRS para la contabilidad del carbono de por vida y la gobernanza.
- Analizar la ponderación relativa del carbono incorporado frente al operativo en los GBRS.
Principales métodos:
- Revisión sistemática y mapeo de los créditos relacionados con el carbono en los principales GBRS.
- Análisis de las definiciones de límites de LCA, gobernanza y mecanismos de verificación.
- Evaluación comparativa de la ponderación del carbono incorporado frente al operativo.
Principales resultados:
- La mayoría de los GBRS priorizan el carbono operativo, subrepresentando el carbono incorporado.
- DGNB es el único sistema que asigna más del 50% de los créditos de carbono a las emisiones incorporadas.
- Existen diferencias significativas entre sistemas en la cobertura de límites, el uso de EPD y la gobernanza.
Conclusiones:
- Los GBRS necesitan ser fortalecidos para integrar LCA de cuna a sitio y mejorar la transparencia de los materiales.
- Los GBRS mejorados pueden apoyar mejor las estrategias de descarbonización de por vida en el entorno construido.
- Esta revisión proporciona información para mejorar los GBRS y avanzar en la descarbonización de edificios.

01:14The Carbon Cycle
44.3K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...
