    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.

    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.
