“…Dicha evaluación se realiza mediante datos de consumo energético, por lo que todos los indicadores analizados son capaces, de alguna manera, de establecer una relación, ya sea de forma directa o indirecta, entre la eficiencia energética de una vivienda y la PE. Otra metodología que permite relacionar la calidad de la vivienda con la PE consiste en la evaluación del confort térmico, como se muestra en los trabajos desarrollados por Sánchez-Guevara, Neila González y Hernández Aja (2018); Boemi y Papadopoulos (2019) y Porras-Salazar et al (2020).…”

Identificar aquellos hogares en una situación de vulnerabilidad a la pobreza energética es el primer paso para abordar una problemática social a nivel mundial asociada a la falta de servicios energéticos mínimos, conocido por los términos anglosajones-Fuel Poverty y Energy Poverty, FP y EP, respectivamente. El concepto FP, definido en el Reino Unido como "la incapacidad para obtener un adecuado confort térmico debido a la ineficiencia de la vivienda", mientras que el concepto EP refleja la imposibilidad de tener acceso a un servicio energético mínimo en países en desarrollo. La falta de un consenso a la hora de definir una ruta clara ha originado que algunos países no la reconozcan como un problema social. La investigación se basa en la revisión de ambos conceptos, a través del análisis conceptual de los términos FP y EP, revisión de indicadores utilizados, estudio de la capacidad de los indicadores para identificar y proponer soluciones a la problemática. Todo ello en relación a los objetivos incluidos: infraestructuras disponibles, eficiencia energética, pobreza social y económica, bienestar y salud social. El resultado es la revisión desde una perspectiva técnica en el sector residencial que ayude a desarrollar soluciones que cubran las carencias encontradas.

“…Residents in economically underdeveloped areas cannot pay for energy or obtain a stable energy supply [31]. Rural populations across South America, including Brazil and Chile, have increasingly called for energy structure adjustments [32]. Low energy consumption and weak energy use capacity problems are noticeable in China; since 1986, China has focused on addressing rural energy poverty [11].…”

Energy poverty due to rising energy demand is a matter of global concern. Therefore, examination of the causes of energy poverty and development of effective solutions are urgent concerns. Using survey data on livelihood development in Tibetan farming and pastoral areas in 2019, this study applied logistic and ordinary least squares models to empirically investigate the factors that influence energy poverty in Tibet. We found that energy poverty is (1) unrelated to age, gender, education, marital status, political and village cadre experience, planting, or expenditures related to religious activities; (2) negatively correlated with migrant work, village status, household income, and traffic conditions; (3) positively correlated with employment, area, and breeding; and (4) both positively and negatively affected by family residence altitude. The results offer new insights and empirical evidence for the identification and elimination of energy poverty, improving livelihoods, and promoting rural revitalisation in Tibet.

“…This background describes a country that, in spite of an increasing awareness about energy efficiency in buildings, still has a long way to go. Chilean researchers have clarified how low insulated houses can have unacceptable low temperatures in winter, as low as 14 • C [42], which, in turn, may lead to a higher prevalence of respiratory illnesses [43]. The thermal adaptation of users in central-southern Chile has its own particularities, but currently, from the adaptive thermal comfort models included in the standards, the model that is part of ASHRAE 55-2017 is the one with the most similarities to those of the users [42,44].…”

Including recycled waste material in cement mixes, as substitutes for natural aggregates, has resulted in diverse research projects, normally focused on mechanical capacities. In the case of recycled glass as an aggregate, this provides a noticeable improvement in thermal properties, depending on its dosage. This idea raises possible construction solutions that reduce the environmental impact and improves thermal behavior. For this research, an extended building typology that is susceptible to experiencing the risk of energy poverty has been chosen. The typology is typical for social housing, built using mortar blocks with crushed glass. First, the basic thermophysical properties of the mortars were determined by laboratory tests; after that, the dynamic thermal properties of representative constructive solutions using these mortars were simulated in seven representative climate zones in Chile. An analysis methodology based on periodic thermal transmittance, adaptive comfort levels and energy demand was run for the 21 proposed models. In addition, the results show that thermal comfort hours increases significantly in thermal zones 1, 2, 3 and 6; from 23 h up to 199 h during a year. It is in these zones where the distance with respect to the neutral temperature of the m50 solution reduces that of the m25 solution by half; i.e., in zone 1, from −429 °C with the m25 solution to −864 °C with the m50. This research intends to be a starting point to generate an analysis methodology for construction solutions in the built environment, from the point of view of thermal comfort.
