- ItemAdaptation and mitigation to climate change of envelope wall thermal insulation of residential buildings in a temperate oceanic climate(Elsevier, 2021) Verichev, Konstantin; Zamorano Toro, Montserrat; Fuentes-Sepúlveda, Armin; Cárdenas, Nadia; Carpio Martínez, ManuelIn the context of climate change, it is difficult to maintain the energy performance of houses, especially in countries with building codes that regulate the maximum allowed amount of energy that a building can consume. For this reason, there is a need for a review of building standards and adaptation to the context of energy performance in planning future projects. The objective of this research was to ascertain the thermal transmittance of external walls for single-family homes and to establish the energetically optimal thickness of thermal insulation by using an energy simulation to maintain heating energy consumption in conditions of climate change while following the state regulations in the Los Ríos region of Chile. It was demonstrated that for each time period and in each geographical location of the region the optimal U-value of the external walls is different. For a house to have a heating energy consumption corresponding to 90 kWh/m2/year, it must have an optimal average U-value of the walls of 0.49 ± 0.11 W/m2K (year 2006 in the study region); however, for the period 2035–2050, this value is expected to reach 0.78 ± 0.14 W/m2K. In addition, it was shown that designing the house with an energy performance perspective of 15 years helps to reduce the carbon footprint of the use of thermal insulation in the walls by 20%. The results obtained demonstrate the importance of considering the effects of future climate change in the housing design process in terms of both energy and environmental.
- ItemAnálisis de envolventes térmicas en el sur de Chile y su influencia en la demanda energética y emisiones de $CO_2$(2018) Carpio Martínez, Manuel; Villanueva, EduardoChile, como la mayoría de los países, presenta un crecimiento continuo en la demanda de energía. Se han fomentado las políticas nacionales relacionadas al ahorro energético en el sector residencial. Una de las soluciones para mejorar el rendimiento energético de las edificaciones es disminuir la perdida de energía a través de la envolvente. En Chile, los requisitos de construcción los reglamenta la Ordenanza General de Urbanismo y Construcción. El objetivo de esta investigación es analizar como diferentes soluciones constructivas tradicionales de la envolvente térmica influyen en la demanda energética y en las emisiones de CO2 en el sur de Chile. Tomando como casos de estudio las capitales regionales de las regiones más australes. La parte analítica de esta investigación consideró una vivienda unifamiliar y 9 tipos de envolventes térmicas tradicionales en que el registro de éstas data de edificaciones construidas desde antes de 1960 hasta la actualidad. Estos modelos fueron simulados en 5 zonas térmicas, obteniendo 45 casos de estudio. La temperatura de confort de las viviendas fue de 20 a 24°C. Los resultados muestran que existe una correlación lineal entre la demanda energética y emisiones de CO2. Se concluye que se puede llegar a reducir la demanda energética un 293% en la zona más cálida y un 248% en la zona más fría construyendo con una solución térmica que cumpla con los requisitos de la reglamentación

- ItemBibliometric Analysis of Urban Coastal Development: Strategies for Climate-Resilient Timber Housing(2024) Andrés García-Ruiz; Manuel Díez-Minguito; Konstantin Verichev; Carpio Martínez, ManuelUrban development in coastal areas has become increasingly important due to the climatecrisis and its effects on sea level rise and extreme events, which increased the vulnerability of coastalzones. Therefore, it is important to analyze possible sustainable development techniques in urbanplanning and residential housing construction based on low-carbon footprint materials such astimber. These techniques should be capable of mitigating the effects of flooding and uncontrolledrises in coastal areas, as well as identifying normative and economic differences in their applicationin the Chilean context. For this purpose, a bibliometric analysis of 3882 articles selected from theWeb of Science database between 1987 and 2022 was conducted, allowing us to identify a range ofpossible solutions to be developed in the study area. This includes evaluating their potential fornormative application and a cost analysis of these solutions. In this regard, housing solutions suchas amphibious houses and houses on stilts are two types of flood-resistant homes that are gainingpopularity worldwide. Following the technical–economic analysis, it was observed that the solutionon stilts can be up to 50% more cost-effective to implement in Chile. However, both options offera promising solution to minimize the risks of coastal flooding and should be taken into account inthe urban planning of coastal areas.

- ItemInfluence of degree days calculation methods on the optimum thermal insulation thickness in life-cycle cost analysis for building envelopes in Mediterranean and semi-Arid climates(2023) Verichev, Konstantin; Serrano-Jiménez, Antonio; Carpio Martínez, Manuel; Barrios-Padura, Ángela; Díaz-López, CarmenThe life-cycle cost analysis (LCCA) is one of the most widely used and validated methods to identify the optimum insulation thickness of the building envelope. This method depends on two parameters—heating and cooling degree days (HDD, and CDD). There are various methods for HDD and CDD calculation, the results of which vary significantly depending on the climatic zone. Therefore, this study aimed to analyse the optimum expanded polystyrene insulation thicknesses of a typical wall in Andalusia, Spain, obtained by the LCCA method to demonstrate variations and uncertainties of the results of the LCCA method based on HDD and CDD calculated by the “hourly”, UKMO, and ASHRAE methods, and with different base temperatures in the conditions of Mediterranean and Semi-Arid climates. On average, the HDD values calculated by using the ASHRAE method were lower, by 12.5%, than those calculated using UKMO and the “hourly” method. The CDD values calculated using the ASHRAE method were lower, by 29%, than those obtained using UKMO and the “hourly” method. Consequently, the optimum insulation thicknesses determined based on CDD and HDD calculated using the ASHRAE method were, on average, 14% underestimated compared with the thicknesses obtained using the UKMO and “hourly” methods. The results obtained showed that with an increase in the continentality of the climate, it becomes crucial to correctly use one or another method for calculating degree days to determine the optimum insulation of the building envelope using the LCCA method, which, in turn, requires the development of validation methods.

- ItemProposal on a new climatic zoning for building in the south of Chile(2021) Verichev, Konstantin; Carpio Martínez, Manuel; Zamorano Toro, Montserrat; Pontificia Universidad Católica de Chile. Escuela de IngenieríaLa zonificación climática para la edificación es una herramienta efectiva de la política de regulación energética. Sin embargo, el cambio climático está provocando que la zonificación actual no se ajuste a la realidad climática existente. Este es el caso del sur de Chile, donde las zonas actuales y los códigos de edificación no pueden garantizar la implementación de edificaciones energéticamente eficientes. Esta tesis ha tenido como objetivo desarrollar una propuesta de zonificación climática para edificación residencial en el sur de Chile, con una metodología reproducible que permita una actualización constante, mitigue y se adapte al cambio climático, reduciendo así los efectos en el medio ambiente en su proceso de climatización. Para ello, en las cinco regiones del país, se ha analizado la adecuación de la aplicación métodos de zonificación: basada en grados-día para calefacción, la bioclimática, la basada en el método de clusterización de los parámetros climatológicos, las dos metodologías del Código Técnico de la Edificación de España y la de la ASHRAE. Como resultado, se identificaron los principales parámetros y características que debe tener una zonificación climática efectiva: (i) tener una metodología reproducible para la actualización constante en contexto de dinamismo climático; (ii) basarse en datos meteorológicos de alta resolución espacial; (iii) tener en cuenta las características climáticas de los períodos de invierno y verano. Considerando lo anterior, se concluye con una propuesta metodológica que ha permitido determinar nuevas zonas climáticas para la edificación, así como proporcionar recomendaciones para el diseño de la envolvente de los edificios, basándose en la metodología del Código Técnico de la Edificación de España y de la ASHRAE. La zonificación climática propuesta permitirá implementar proyectos de viviendas con altos estándares energéticos, desarrollar códigos de construcción dinámicos que permitirán mitigar los efectos del cambio climático y adaptar la edificación a los mismos.
