    Calificación energética obligatoria para viviendas: aportes para la discusión
    (Centro de Desarrollo Urbano Sustentable, 2020) Encinas Pino, Felipe Alfonso; Bustamante Gómez, Waldo Enrique; Ladron De Guevara González, Felipe Andres; CEDEUS (Chile)
    El proyecto de Ley sobre Eficiencia Energética establece la obligatoriedad de la Calificación Energética de Viviendas, que hasta la fecha, había sido de aplicación voluntaria. Si bien esto puede representar un avance en la reducción de las asimetrías de información que aqueja a los consumidores, requiere de un esfuerzo significativo de comunicación e implementación y la complementariedad con otros instrumentos para que sea efectiva.

    Potential of Mid-Rise Social Residential Buildings to Reach Net Zero Energy Building Standard in Two Different Climates of Chile
    (International Building Performance Simulation Association, 2020) Tori Kendall, Felipe Andrés; Vera, Sergio; Bustamante Gómez, Waldo Enrique; Sills, Pablo
    The Net Zero Energy Buildings (NZEB) are a real solution to reduce the energy consumption and greenhouse gas (GHG) emissions generated by the building sector. Thus, many developed countries have conducted different studies for the development of public policies that encourage the implementation of NZEB. Chile adopted as environmental goal for the coming years reducing the GHG emissions by 30%, but the instruments to accomplish them have not been clearly defined. The NZEB might be a key strategy to reduce the GHG emissions. However, there are no studies that evaluate the performance of NZEB in Chile. The aim of this research is to determine the potential of mid-rise social residential buildings to reach the NZEB standard in Santiago and La Serena. In particular, mid-rise social buildings are selected as representative for this study through the use of a multi-criteria matrix. The electric consumption of buildings and photovoltaic production are simulated in EnergyPlus. The optimizations of the energy efficiency measures and the configurations of the photovoltaic systems are carried out in GenOpt. The results show that mid-rise social residential buildings are very close to reach the NZEB standard and through the optimized energy efficiency measures, the electric consumption of the building is reduced by up to 28%. Therefore, mid-rise social residential buildings have potential to reach NZEB standard but other measures must be studied.

    Recomendaciones para reducir la contaminación del aire debido al uso de leña en viviendas
    (2024) Simon, François; Bustamante Gómez, Waldo Enrique; CEDEUS (Chile)
    Este documento presenta evidencia sobre la contaminación del aire causada por partículas de 2,5 μm (MP2,5) debido a la quema de leña en el sector residencial, excluyendo otras fuentes estacionarias y móviles, y su impacto en la salud pública y el entorno construido. Un estudio de caso en Temuco se presenta para ilustrar la problemática. Se analizan los marcos de políticas vigentes y se exploran oportunidades para la implementación de nuevas estrategias y políticas públicas capaces de reducir esta contaminación del aire

    Techos y muros vegetativos en chile: propuesta de política pública basada en i+d para la implementación de techos y muros vegetativos en chile
    (Centro de Desarrollo Urbano Sustentable, 2023) Vera Araya, Sergio Eduardo; Rojas Mondaca, Aldo Nicolás; Viecco Márquez, Margareth; Bustamante Gómez, Waldo Enrique; CEDEUS (Chile)
    La infraestructura verde de edificios, tales como techos y muros vegetativos, son tecnologías reconocidas por proporcionar diferentes beneficios ecosistémicos a nivel de edificios, pero por sobre todo a nivel urbano. En el año 2010 nos motivó el poder cuantificar algunos de estos beneficios ecosistémicos en climas semiáridos como el de la zona central de Chile, caracterizada por altas temperaturas y radiación solar durante gran parte del año, y muy bajas precipitaciones concentradas en pocos días, sumado a la tremenda escasez hídrica de hace más de dos décadas. Estas condiciones imponen desafíos complejos a los techos y muros vegetativos, que son muy importantes comprender y cuantificar para apoyar el diseño, construcción y mantención de estos, tal que provean uno o más beneficios ecosistémicos, que potencialmente pueden generar enormes beneficios socioambientales en las urbes.

    Timber Biogenic Carbon Stock in the Urban Environment: Santiago City as a Second Forest
    (Multidisciplinary Digital Publishing Institute (MDPI), 2025) Victorero Castaño, Felipe Andrés; Bustamante Gómez, Waldo Enrique
    Urban environments significantly contribute to carbon emissions, both through operational processes and the embodied emissions of construction materials, thus exacerbating climate change. Nevertheless, urban timber structures offer a viable alternative by acting as carbon sinks, capable of sequestering carbon for decades or even centuries. This study develops and applies a methodology to quantify the biogenic carbon stored in Santiago City’s timber-based buildings, conceptualized as a “Second Forest” that transfers and preserves the carbon capture capacity of trees in the built environment. The analysis estimates that Santiago’s urban timber constructions have expanded their wood-built surface area by 192,831 m2 over the past eight years, reflecting the growing adoption of timber in urban construction. During the same period, biogenic carbon storage increased from 199.78 kt to 202.73 kt, equivalent to 10.84 kt of CO2 under average conditions. These findings highlight the potential of urban planning strategies, such as promoting taller timber buildings and adopting circular timber practices, to enhance carbon sequestration and reduce reliance on carbon-intensive materials. This research highlights the fundamental role that timber buildings play in urban climate change mitigation, positioning them as active contributors to global carbon management efforts.
