Sites of Violence, Sites of Peace, Sites of Justice: Transforming the Relational Landscape of Yogyakarta

The collaborative “Sites of Violence, Sites of Peace” project seeks to transform the relational landscape of Yogyakarta by enabling new intergenerational conversations about the 1965 politicide in Indonesia and further injustices with other marginalized communities. This community-engaged project developed walking tours of (largely unacknowledged) sites of historic violence: a colonial fort turned national museum, a derelict office building, a refurbished bank. Through these tours, sites of past suffering are activated by unheard survivor testimonies, making visible historical injustice and its contemporary and enduring significance. Unsettling the dominant spatial arrangement of Yogyakarta, the tours rewrite the city as a space where injustice and persecution are experienced. Crucially, the tour is also a relational encounter, facilitating intergenerational conversations that challenge social and political exclusionary norms. It, thereby, enables a form of relational justice, which requires active involvement from fellow citizens, not solely redress from the state.

Control solar en envolvente vidriada tropical para mejorar el desempeño energético-ambiental por climatización

Con el objetivo de fundamentar la estrategia de control solar como propuesta efectiva en la rehabilitación energética de un edificio de oficinas de los años 50´s, se realiza un diagnóstico del comportamiento de la demanda energética por climatización debido a su fenestración translúcida. Para el estudio se modelan los tipos de espacios más comunes (con una, dos o tres fachadas de vidrio) los cuales son objeto de simulaciones horarias que permiten pronosticar la demanda de energía anual para enfriamiento. Además, se determina el impacto ambiental que provoca este tipo de carpintería en las condiciones tropicales, de alta incidencia solar y de producción de energía de Cuba. Se utiliza Energy Plus, el motor más reconocido y avanzado de Simulación Energética de Edificios, desarrollado por el Departamento de Energía de los EEUU. Fundamentadas en los resultados se realizan y evalúan dos propuestas de diseño de control solar en las fachadas sureste y suroeste, las cuales demuestran su efectividad a partir del ahorro pronóstico anual de energía eléctrica por climatización consecuencia del recurso de sombreado. También se demuestra la influencia de la orientación en el diseño de los elementos componentes de la envolvente vertical para favorecer, con su especificidad local, la eficiencia energética, la identidad; así como la cultura energética convocada por la dirección de la nación. In order to justify the strategy of solar control like effective proposal in the energetic rehabilitation of an office building of the years 50 ´s. This paper present a diagnosis of the behavior of the cooling energetic demand due to its glazed windows. For the study are modeled the types of spaces more common of the building (with one, two or three glass facades) which are simulated each one hour to predict the annual energy demand for cooling. In addition, the environmental impact is determined that causes this window type in the tropical conditions, of high solar incidence and dependence of fuels imported for the energy generation in Cuba. It is used Energy Plus the most advanced motor in Energy Simulation of Buildings, developed by U.S. Department of Energy Building Technologies Office. Based in the results are carried out and evaluate three designs of solar control in the facades southeast and southwest, which demonstrate their effectiveness in the saving annual of electric power for cooling. The results demonstrate the influence of the orientation in the design of the vertical envelope component elements to favor, with their local specificity, the energy efficiency and the identity, as well as the energetic culture convoked by the government of the nation.
