“…Desde la extracción de la materia prima hasta la demolición del edificio al final de su vida útil, la madera tiene una huella ambiental menor que la del acero o el concreto en cuanto al uso de energía, emisiones de efecto invernadero, emisiones al agua y producción de desechos sólidos [16]. Hay que tomar en cuenta que los indicadores más significativos en cuanto al impacto ambiental son la huella de carbono y la energía empleada que requiere cada sistema estructural [17]. Según Ravenscroft, "los componentes de los edificios de madera consumen solo el 50% de la energía necesaria para producirlos en hormigón y apenas un 1% para producirlos en acero" [18].…”

La madera maciza en los últimos años ha generado gran interés en la industria de la construcción. Ya que, gracias a sus configuraciones como madera laminada (GLT y CLT), se ha podido construir edificios de gran altura con su estructura (vigas, columnas, losas y paredes) completamente hecha de madera. A medida que mejora la tecnología, la brecha entre el uso de hormigón armado, acero y madera será menor, es posible que dentro de unos años los edificios de madera sean tan comunes como sus análogos de hormigón y acero. En el Ecuador, la construcción en madera es bastante limitada. Su uso más común es con la caña guadua guadua angustifolia y maderas duras para casas de hasta dos pisos. La madera maciza puede cambiar esta percepción e introducirse como una alternativa al hormigón y el acero. Al ser relativamente nueva su implementación en el mundo, hay la oportunidad para desarrollar y explotar el potencial de una nueva industria en el país. Sin embargo, a pesar del potencial que tiene este material, es posible que su introducción no genere el impacto esperado y esto puede ocurrir por una amplia gama de factores. Este estudio desarrolló un cuestionario usando literatura existente sobre la madera maciza en relación a: la producción de materia prima, el proceso de manufactura, el proceso de construcción, el mantenimiento, el contexto cultural y el impacto ambiental. Con esto se realizaron 10 entrevistas a profesionales relacionados a la industria de la construcción. Las respuestas se transcribieron, analizaron y codificaron para identificar cuáles son las barreras percibidas de acuerdo con la introducción de este sistema constructivo en el Ecuador. Al final, el artículo propone caminos para profundizar la investigación académica así como el uso profesional de este material.

Buildings and facilities undergo several stages: the product stage, the construction stage, the use stage, the end-of-life stage, and the recycling stage. The life cycle of any facility or building contributes to embodied carbon (EC) emissions. The product stage, also known as the cradle-to-gate stage (A1–A3), registers the highest emissions, estimated to account for 70% of the total environmental impact. The continuing population growth in Saudi Arabia necessitates urgent action to identify and implement solutions for reducing greenhouse gas emissions and mitigating environmental risks. This study investigates the optimal method to analyze the grade of concrete for specific structural elements (columns) in a particular work area, adhering to accurate and methodological standards outlined in the Saudi Building Code (SBC). The bill of quantities (BOQ) determined the amount of building materials for the structure considered in this study. Reliable embedded carbon coefficients (ECCs) for structural materials such as concrete and steel were determined following life cycle assessment principles. They were analyzed using the Inventory of Carbon and Energy (ICE; Version 2.0) and Global Warming Potential (GWP). The obtained values varied based on the components of each mixture. This study determined the cost of each concrete mixture and steel, selecting the optimal mixture based on both EC and material cost. Since the quantity of cement significantly affects EC emissions in a concrete mixture, it is essential to select appropriate plasticizers and concrete types. This study evaluated the C30, C40, C50, C60, and C70 mixtures. Among these, the C70 mixture demonstrated the best environmental impact and was the least expensive compared to the basic C40 mixture for the estimated quantities of concrete and steel. The estimated reductions in cost and environmental impact were 33% and 27%, respectively. This groundbreaking study paves the way for low-carbon structural design in large hotels across Saudi Arabia, offering valuable insights for future projects and contributing significantly to energy conservation.

Environmental Impact of Textile Reinforced Concrete Facades Compared to Conventional Solutions—LCA Case Study

et al. 2019

Pitch-faced concrete is becoming a very popular element of modern architecture in the 21st century. In particular, the demand for concrete facades is increasing globally. On the other hand, climate change, environmental degradation, and limited resources are motivations for sustainable building materials. The construction industry is one the highest emitters of CO2 and other greenhouse gases, in which concrete plays a major role. Thus, reduction in the volume of concrete consumption is essential to control greenhouse gases. One approach to this problem is to use textile reinforced concrete (TRC). The main aim of the present study was to compare the subtle TRC facade made of three different types of technical textile rovings (glass, carbon, and basalt) with ordinary facades reinforced by steel reinforcement (ORC). The goal was to compare the basic environmental impact potential according to product category rules (PCR) for concrete structures. The functional unit was defined as an experimental facade with an area of 60 m2 and a 100-year lifespan. Inventory data were elaborated for concrete, steel, and textile fiber production; the building site; service life; demolition; and final disposal. The main life cycle assessment (LCA) parameters were global warming potential (GWP), ozone depletion (ODP), acidification (AP), eutrophication (EP), abiotic depletion (ADP), and photochemical oxidant creation (POCP). All the data used in the work were related to Czech Republic. Textile reinforced concrete facades appeared to be more environmentally friendly in four of six impact categories by an average of 30%. The results of the present study revealed that, in comparison to ORC, TRC has a lower environmental impact for the given conditions and thus good potential for use in sustainable construction.
