Arte urbano, política y memoria en 2019: Primeros pasos hacia la conformación de un archivo del muralismo político en Santiago de Chile / How to support the 2030 Agenda from the Smart Community Centers (CECIs-MICITT) stored in the National Library System (SINABI-MCJ)

Resumen El presente ensayo nace desde la inquietud en torno a la volatilidad del grafiti como obra, imagen e intervención del espacio urbano y busca ser una exploración de lo que ocurre con el grafiti muralismo en Santiago de Chile. Se centra en la vocación política de éste considerando como precedentes importantes el muralismo Mexicano como también las Brigadas Ramona Parra y Elmo Catalán. En el trabajo se hace énfasis en el muralismo con vocación política y mensajes explícitos llevándolos a lo que se ha entendido como el rol social del arte desde autores como Nelly Richard o Gaspar Galaz, aludiendo a la obra de grafiteros como Agotok, UFO o Aguarda Kiltro con importantes intervenciones en la zona sur de Santiago, sector caracterizado por el hábitat popular. A nivel metodológico se realiza una exploración en la Avenida Santa Rosa, una de las principales arterias de la zona sur de Santiago, con gran cantidad de obras en sus muros, concluyendo en el centro cultural donde se encuentra el trabajo "el gol de Chile" del destacado muralista Roberto Matta. Se hace énfasis en la necesidad de registro fotográfico del arte urbano, para llegar a formar un fondo adecuadamente ordenado para la conformación de un archivo del arte urbano que sería un campo altamente dinámico y en constante disputa, siendo un ejercicio interesante para recuperar y fortalecer la memoria histórico social. Como conclusión se destaca que el presente esbozo se plantea como un primer paso, un ejercicio reflexivo sobre la necesidad de registrar y archivar como ejercicio de memoria que puede resultar en experiencias destacables.

Abstract This essay was born from the concern about the volatility of graffiti as a work, image and intervention of urban space and seeks to be an exploration of what happens with mural graffiti in Santiago, Chile. It focuses on the political vocation of the latter considering as important precedents the Mexican muralism as well as the Ramona Parra and Elmo Catalán Brigades. The work emphasizes muralism with a political vocation and explicit messages leading them to what has been understood as the social role of art from authors such as Nelly Richard or Gaspar Galaz, referring to the work of graffiti artists such as Agotok, UFO or Aguarda Kiltro with important interventions in the southern area of ​​Santiago, a sector characterized by the popular habitat. At the methodological level, an exploration is carried out on Santa Rosa Avenue, one of the main arteries of the southern area of ​​Santiago, with a large number of works on its walls, concluding in the cultural center where the work "the goal of Chile" is located of the prominent muralist Roberto Matta. Emphasis is placed on the need for a photographic record of urban art, in order to form a properly organized fund for the conformation of an archive of urban art that would be a highly dynamic and constantly disputed field, being an interesting exercise to recover and strengthen the social historical memory. In conclusion, it is highlighted that this outline is presented as a first step, a reflective exercise on the need to register and file as a memory exercise that can result in outstanding experiences.

Air temperature and mean radiant temperature data, collected and simulated across a radiantly-heated high-bay laboratory.

To better understand the extent of how the air temperature and mean radiant temperature may vary both spatially and temporally in a radiantly heated space, we conducted a seven-day experiment in the architectural laboratory at School of Architecture, Princeton University. The primary intent of this paper was to decouple the measurement of the air temperature and mean radiant temperature. We collected a large dataset that shows temporal and spatial variations. To do so, we used non-contact infrared thermometer to measure the surface temperatures of the surrounding surfaces inside the laboratory. The geometry of the laboratory is simplified into a box, the corresponding view factor from every point within the box can be calculated towards each internal surface. These view factors are then combined with the measured surface temperatures to produce mean radiant temperatures. This spatial mean radiant temperature distribution was then compared with the air temperature distribution measured by the air temperature sensors suspended from the ceiling of the laboratory. We believe making these data available will help future researchers working on similar problems to develop protocols than the state-of-the-art measurement techniques observed among different thermal comfort or radiant heat transfer research.
