“…The importance of having air-conditioning systems in environments with hot climates can be satisfied with unconvential solutions in order to realize a living comfort without consuming high quantities of depletable energy resources with a resulting higher environmental respect [37][38][39]. A possible solution, exploiting solar energy in countries that have high solar radiations for long periods during the year, can exert absorption heat machines.…”

Abstract:The increasing importance of a significant reduction of CO 2 emissions in the atmosphere asks the scientific community to find other solutions than fossil fuels with respect to the air conditioning of indoor environments. Nowadays, a priority is represented by the energy expenses reduction, in which residential buildings report one of the highest energy consumption levels among developed countries. The application of alternative energies in residential buildings is an issue debated in the European Commission for the reduction of greenhouse gas emissions with the objective to obtain 20% of the demand from renewable sources. This paper suggests the application of the solar energy stored in solar ponds to air-condition small residential buildings, through the use of absorption machines. A feasibility analysis was carried out in some places characterized by climates that are suitable to make the solution here suggested sustainable from an energetic point of view. Buildings characterized by different boundary surface/volume ratios were examined and the energy saving, the amount of CO 2 that was not emitted in the environment and the return of investments with respect to a more traditional solution were evaluated.

“…Smart cities, thus, represent a version of sociotechnical hybridity as a cyber-physical system [29,30]. The conception and application of cyber-physical systems are rapidly developing across many disciplines, with one of the recent advancements also being the notion of "cyber-physical-social systems" [31].…”

This paper problematizes the dichotomy of hard (technocratic) and soft (societal) approaches to the smart city. Smart cities are reviewed as hybrid spaces that transcend the sum of the social and the technical. By providing platforms for enabling, monitoring, digitalizing, formalizing, and amassing information about collective and personal experiences and behaviors, smart cities accelerate the customization of existing urban services and establish new spaces of socialization, accumulation and regulation, including in hitherto hard-to-reach realms of everyday and personal life. These experiences signify the emergence of cyber-physical-social spaces, featuring the hybridization of the digital, governance, and sociocultural domains. The production of such hybrid spaces of governance is reviewed through 50 urban-level strategies for smart cities in different countries across the world. The analysis confirms the tendencies towards a hard/soft fusion and the ever-deepening interpenetration of the digital, physical, and social elements in smart cities. This suggests epistemological problems of separating the hard and soft domains. However, this integration still creates political and analytical tensions that are arguably evident in the early stages of the digital transition.

“…Otros por ejemplo resaltan los diferentes métodos y técnicas que se han empleado en todo el mundo para lograr reformas de rendimiento y adaptar los edificios a los estándares actuales de eficiencia energética y confort térmico es esencial para mejorar la sostenibilidad y el rendimiento energético [18]. Así como también resaltan que el uso de un software dinámico es más apropiado para tratar las propiedades inerciales de la estructura para calcular de manera más detallada las cargas térmicas anuales y obtener más información sobre las zonas de calentamiento individuales [19].…”

El objetivo del presente trabajo es evaluar experimentalmente el desempeño térmico de un Módulo Experimental de Vivienda (MEV), construido en la región Alto Andina, mediante la evaluación sistemática de doce configuraciones de operatividad diferentes, desde el manejo nocturno de contraventanas hasta actividad humana, uso de cocinas a gas y uso de dos sistemas de calefacción solar activos. Este objetivo se fundamenta en las mediciones de temperatura y humedad, considerando la primera como el parámetro principal de análisis térmico para verificar el desempeño térmico del MEV mediante la variación de la temperatura interior respecto al exterior, según la configuración del MEV dado a que la variación entre la temperatura diaria promedio interior y exterior muestra la eficacia de las estrategias de calentamiento o enfriamiento. En base a ello, los incrementos de temperatura en el interior del MEV, considerando una operatividad concienzuda de sus técnicas bioclimáticas implementadas, son del orden de 9,5 °C en promedio y, de hasta 16,6 °C en horas críticas de la madrugada respecto a la temperatura exterior de -7,1 °C a las 6 a.m. El estudio se complementa con simulaciones térmicas dinámicas utilizando el software EnergyPlus apoyado del entorno gráfico en 3D SketchUp, e interfaz OpenStudio para determinar la temperatura interior y validarlo con la temperatura interior real medida. Los resultados muestran un buen acuerdo entre la simulación y los datos experimentales, con un error cuadrático medio de 15 y 16 % en los ambientes del MEV.
