Mapa energético-solar de Concepción: cartografía urbana del consumo energético y captación solar en edificaciones residenciales de Concepción, Chile

With the aim of promoting solar energy use in cities, this paper presents an urban assessment of energy consumption and incident solar radiation, applied to different residential typologies, categorized by block in Concepcion, Chile. The categorization was done through surveys, socioeconomic records, aerial photographs, building typologies and simulations, which were implemented in a Geographic Information System (GIS). The identifi ed ranges and zones give, as a fi rst result, the differential distribution of energy consumption and solar potential, which constitute the basis for implementing an array of renewable energy. This work shows that high-density sectors have less solar potential in Concepcion, whereas low-density sectors show a surplus, which could allow achievement of a balance in the solar energy matrix by energy transfer between sectors of the city.
