    Mapping Energy Poverty: How Much Impact Do Socioeconomic, Urban and Climatic Variables Have at a Territorial Scale?
    (MDPI, 2022) Encinas, Felipe; Truffello, Ricardo; Aguirre-Nunez, Carlos; Puig, Isidro; Vergara-Perucich, Francisco; Freed, Carmen; Rodriguez, Blanca; CEDEUS (Chile)
    Energy poverty, considered a form of deprivation distinct from income poverty, is associated with three factors: low-income levels, high energy costs, and poor residential energy efficiency. It is necessary to study the socio-spatial distribution of energy poverty, particularly in metropolitan areas, due to persistent socioeconomic segregation and their public agenda implications, including the U.N. SDGs. A model of these characteristics can propose a spatial analysis of urban and climate implications, contributing evidence for public policy. This article aims to address energy poverty from a spatial approach extended to the urban area in Santiago de Chile through an exploratory model that estimates the impact of socioeconomic, urban, and climatic variables at a territorial scale on the performance of homes. Using a geographical weighted regression with the inside home temperature in winter as the dependent variable, the independent variables were the percentage of professionals, NDVI, annual thermal amplitude, and housing material quality. A housing quality pattern that acts as a proxy for vulnerability to energy poverty was found, repeating the distribution pattern of the different socioeconomic sectors. The findings incorporate a new interpretive matrix into the complex reproduction of segregation and inequality in a capital city from a developing country.

    Perceptions, Tensions, and Contradictions in Timber Construction: Insights from End-Users in a Chilean Forest City
    (2024) Encinas, Felipe; Truffello, Ricardo; Ubilla, Mario; Aguirre-Nunez, Carlos; Schueftan, Alejandra; CEDEUS (Chile)
    The study addresses the underutilisation of wood in construction in Chile, particularly given the country's robust forestry sector. The research investigates perceptions, tensions, and contradictions among end-users regarding timber construction in Valdivia, a city with a mixed forestry industry. Methods included a comprehensive survey of 96 households across various socioeconomic clusters, utilising descriptive and exploratory statistical analyses. Key findings reveal persistent negative perceptions about wood's durability, fire resistance, and maintenance costs. However, positive aspects, such as lower construction costs and adequate thermal comfort, were also noted. Surprisingly, concerns were raised about wood's environmental impact, including deforestation and its role in combating climate change, contrasting with the material's known ecological benefits. The study concludes that these perceptions are deeply influenced by ideological and sociopolitical factors, suggesting that mere marketing strategies may not suffice to alter public opinion. Instead, a collaborative effort involving public policy, industry advancements, and transparent scientific communication is essential to promote the benefits of timber construction and address the entrenched biases.

    Pobreza energética y segregación espacial: nuevas dimensiones urbanas para la desigualdad.
    (UPC. Universitat Politècnica de Catalunya, 2019) Encinas Pino, Felipe Alfonso; Aguirre Nunez, Carlos Andres; Truffello Robledo, Ricardo Enrique; Puig Vazquez, Isidro Abraham; Hidalgo Dattwyler, Rodrigo Alejandro
    El concepto de pobreza energética nace a principios de los años 90 en el Reino Unido como la incapacidad de obtener en un hogar la cantidad adecuada de servicios energéticos por el 10% del ingreso familiar (Boardman 1991). Esta definición posteriormente ha sido complementada con aspectos constructivos y de habitabilidad, a partir de, por ejemplo, el establecimiento de una temperatura límite para la obtención de confort (DOE 1996).En la literatura internacional más reciente es posible encontrar definiciones con un fuerte sesgo interdisciplinar a partir de la accesibilidad a 3 umbrales de vulnerabilidad: tecnológico, físico y económico (González-Eguino 2015). Este último es el más ampliamente utilizado en países desarrollados, principalmente asociado al consumo de calefacción para uso doméstico (concepto más preciso de “fuel poverty”), aunque se reconoce que tiende a subestimar la cantidad de hogares que efectivamente no puede costear el consumo energético para estas mínimas condiciones de habitabilidad, o la provisión de otras demandas de energía, que constituyen el denominado umbral tecnológico (Mould y Baker 2017; Bouzarovski y Petrova 2015). Por otra parte, el umbral físico ha sido estudiado de manera más reciente desde el confort térmico, específicamente en su relación con la vulnerabilidad y salud, encontrando correlaciones significativas con respecto a las características constructivas de las viviendas (Grey, Jiang y Poortinga 2015; Atsalis et al. 2016).En este contexto, la incorporación de metodologías de segregación socio-espacial para enriquecer este concepto es de muy reciente data y todavía no ha sido aplicado a nivel nacional. Este enfoque resulta importante, puesto que permite identificar zonas de aglomeración de pobreza energética, aspecto importante para el diseño de políticas urbanas.

    Territorial Infrastructure Support Index (ISIT): A theoretical and empirical contribution to the analysis of lag zones in Chile
    (2023) Orellana Ossandón, Arturo; Truffello Robledo, Ricardo; Moreno Alba, Daniel Felipe; Altamirano López, Héctor; Flores Castillo, Mónica Andrea; Puig, Isidro; Instituto de Estudios Urbanos; UC
    Through a review of the literature on infrastructure, a study of internationalexperiences, expert knowledge, and the elaboration of a Territorial Infrastructure SupportIndex (ISIT), this paper provides a comparative analysis of the development conditions –regarding infrastructure and services – for the location of productive economic activities,at the regional and provincial level in Chile. The results show contrasts between regionsand within them, revealing the state of the current situation for each of the six dimensions:Water, Energy, Telecommunications, Roads, Logistics, and Resilience, as well as for theirsynthetic indicator ISIT. The results of the ISIT have been contrasted with the recentdefinitions made by the Government of Chile regarding the definition of lag zones, findingimportant coincidences at the provincial level that allow validating the ISIT as a tool forthe analysis of gaps in infrastructure and equipment for development of economic andproductive activities in Chile.
