    Ciudades sostenibles en madera. Políticas públicas para la densificación de ciudades con bajas emisiones de carbono
    (Centro de Políticas Públicas UC, 2024) Victorero Castaño, Felipe Andrés; Caamaño González, José Luis; Méndez López, Daniela
    El presente artículo revisa políticas públicas internacionales y el contexto chileno para analizar e identificar instancias que promuevan el uso de la madera en la densificación urbana como medio para capturar y almacenar carbono, contribuyendo a las metas de carbononeutralidad al 2050. A nivel global, la construcción en madera se ha destacado como una estrategia eficaz para reducir las emisiones incorporadas en edificaciones, gracias a su capacidad de almacenamiento de dióxido de carbono (CO2) y su integración en sistemas de economía circular, como lo demuestran los casos de Finlandia, Canadá y Francia, que han implementado instrumentos regulatorios, económicos y educativos para fomentar su adopción. En Chile, a pesar de contar con una sólida industria forestal y compromisos internacionales como el Acuerdo de París, las políticas actuales no explotan plenamente el potencial de la madera en la construcción urbana, limitándose a iniciativas acotadas a regiones específicas o proyectos puntuales, lo que contrasta con la necesidad de abordar un déficit habitacional de más de 550.000 viviendas y mitigar las significativas emisiones del sector construcción. En este marco, se proponen tres estrategias clave para superar estas limitaciones: (i) la entrega de información y divulgación sobre los beneficios de la construcción sustentable en madera; (ii) la promoción del uso de productos de madera para la captura de carbono en nuevas edificaciones; y (iii) el apoyo al desarrollo de construcciones sustentables en madera como elementos detonantes de la industria. Estas estrategias buscan consolidar la madera como un material esencial para la densificación urbana sostenible y posicionar a Chile como líder en la lucha contra el cambio climático.

    Phases of architectural design in the development of a modular and panelized wooden building with early integration process
    (2025) CaamañoLorca, José Luis; Lorca Pavez, Fabiana Gloria; Méndez López, Daniela
    The article analyzes a wood architecture project as a sustainable solution for the construction of industrialized social housing buildings in Chile. It highlights the importance of early integration of architectural and engineering teams. The project, a 4-story light wood frame building, underscores the need for standardization and precision in manufacturing to avoid transportation and assembly issues. A design divided into four phases is proposed: conceptualization, schematic design, architectural design, and manufacturing adjustments. Each phase involves collaboration among various professionals to optimize design and construction. The case study analysis presents early integration and standardization as essential factors to improve quality, efficiency, and reduce costs in the construction of wooden buildings, proposing them as a viable and sustainable option in the Chilean urban context.

    The opportunities of timber frame construction, under building energy efficiency codes and environmentally friendly public policies, in developing countries
    (World Conference on Timber Engineering (WCTE), 2021) Victorero Castaño, Felipe Andrés; Pavez Gallegos, Danny Leonel; Méndez López, Daniela
    Timber construction is widespread in developed countries, for its multiple benefits, although developing countries such as Latin Americans tend to use other materials as an alternative. It can be explained by many factors, being one of the most important the lack of an industry that can give cost-competitive buildings, as well as national codes requirements to promote good construction standards and energy efficiency minimum requirements. Chile, one of the leading timber construction countries in Latin America, presents a chance to study how modern timber frame construction can develop under different geographical, climatic, and industry conditions. This work studies the timber frame building's opportunities, under five different cases, by evaluating construction costs and the impact of envelope's thermal insulation for energy efficiency. The result of this study shows that Chilean timber frame houses are more cost-competitive than other materials alternatives; and even though timber frame multistory buildings, are not as competitive when direct construction costs are compared with other materials, they could present fewer operation costs on their life span. Also, this study shows that minimum thermal insulation standards could contribute, at least at first, to making timber buildings more economically attractive against other materials, and especially in colder climates. Moreover, public policies focused on measuring and pricing constructions environmental impacts, such as CO2e emissions, could also promote the use of more sustainable and renewable materials like timber frame constructions in developing countries, and need to be evaluated to reach a more sustainable model in the future.

    Using the DFMA approach in the early integration of actors for the design of an industrialized timber building – case study
    (World Conference on Timber Engineering 2025, 2025) Méndez López, Daniela; Lorca Pavez, Fabiana Gloria; Carpio Martínez, Manuel
    Design for Manufacture and Assembly (DfMA) is a methodology that optimizes the design process to facilitate manufacturing and assembly, promoting more efficient and cost-effective construction. This study describes the process of early integration of actors in a case study of an industrialized timber building in Chile, framed in the Housing Emergency Plan. Involving architects, engineers, manufacturers, and builders from the early stages, the DfMA methodology was applied to improve communication and coordination between all actors. Five design stages were identified based on the RIBA guide, and BIM and modeling tools were used to integrate information from all participants. The results indicate that, although design time increases, production is more efficient, with fewer errors and rework, and higher construction quality. This study provides a framework for future projects in the construction industry, highlighting the importance of early integration and use of digital tools. Future work should validate time and cost savings, reduction in waste, improvement in quality and processes in manufacturing and construction phases.
