Energy poverty risk mapping methodology considering the user's thermal adaptability: The case of Chile Energy Sustain. Dev. (IF 3.61) Pub Date : 2020-08-12 Alexis Pérez-Fargallo, David Bienvenido-Huertas, Carlos Rubio-Bellido, Maureen Trebilcock
Today, identifying energy poverty is one of the scientific community's challenges. In this sense, using Geographic Information Systems (GIS) assumes getting to know which areas are the most vulnerable. This study considers the development of a new territory energy poverty evaluation indicator, called Poverty Adaptive Degree Hourly Index (PADHI). The novelty of this indicator is that it combines the
