- ItemAn Approach Concerning Climate Change and Timber Building Resilience: Araucanía Region, South Chile(MDPI, 2021) Prieto Ibáñez, Andrés José; Verichev, Konstantin; Ferreira, Ana da SilvaThis study analysed climate change effects concerning the resilience of timber buildings located in southern Chile, specifically in two cities: Collipulli and Temuco (Araucanía Region). A digital fuzzy logic method was used in a set of timber buildings declared as heritage conservation buildings by Chilean Government standards. The outcomes revealed that climate change impacts did not substantially alter the functional performance of the set of heritage timber buildings examined. This study’s results can assist in developing upcoming strategies or recommendations that can support adaptation policies for administering architectural heritage regarding climate change forecasts. These data will invaluably help stakeholders who support the conservation of timber structures located in the southern environment of Chile and under the changing climatic hazard

- ItemDynamics of Built-Up Areas over The Past 30 Years According to Remote Sensing Data in the City of Valdivia, Chile(IEEE, 2018) Verichev, Konstantin; Mikhaylyukova, Polina; Salazar, Cristian; Carpio Martínez, ManuelThe dynamics of built-up areas over the last 30 years in the city of Valdivia was analyzed according to Landsat satellite imagery data. For ETM+/Landsat-7 and OLI/Landsat-8 instrumentation systems, method of automatic satellite image interpretation of build-up areas showed inaccuracy, less than 1%, compared to visual method. For TM/Landsat-5 instrumentation system, method of automatic satellite image interpretation of build-up areas demonstrated unsatisfactory results. Since 1987 and by the year 2017 the city's built-up areas increased by 61% with the population growth of 66% within the same time period.

- ItemHow do urban heat islands affect the thermo-energy performance of buildings?(ELSEVIER SCI LTD, 2022) Lopez-Guerrero, Rafael E.; Verichev, Konstantin; Moncada-Morales, Guillermo A.; Carpio, ManuelCities occupy 3% of the surface of the planet, but account for 60-80% of energy consumption and 75% of carbon emissions. Likewise, buildings consume 35% of the energy and emit 38% of global greenhouse gases. Cities can aggravate such problems further by generating the phenomenon of urban heat islands (UHI). Few studies have evaluated the state of the art in UHIs' influence on buildings' energy performance, so the present research aims to analyze the main studies evaluating the thermo-energy behavior of buildings subjected to UHI. This was done with a systematic literature review and a scientific mapping of the publications present in Web of Science until 2021. 100 articles were selected for analysis in this review. The results point to an important evolution in the study of parameters affecting urban buildings' performance, in addition to the analysis of different urban land uses as a strategy to sectorize UHI. Such scientific evolution is analyzed and discussed in four-time segments. Fragmentation on building cooling loads and the energy penalty index derived from UHI are discussed, resulting in an average cooling penalty of 6.63 kWh/m2/y/degrees C and 3.81 kWh/m2/y/degrees C, for residential and office use respectively. This study presents limitations and proposes applications for the use of this index, as well as prospects for future studies and main research gaps in the area.
- 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.
