Índice de reflectancia solar de revestimientos verticales: potencial para la mitigación de la isla de calor urbana

Noelia Liliana Alchapar; Erica Norma Correa; María Alicia Cantón

La condicion artificial del medio urbano modifica el consumo de energia y el confort termico. El incremento de las temperaturas de una ciudad en relacion a las areas perifericas conduce a la formacion de una Isla de Calor Urbana. Es por ello, que trabajar sobre las propiedades termo-fisicas de los materiales (techos, pavimentos y fachadas) es una estrategia de mitigacion viable para disminuir las temperaturas de una ciudad. El objetivo principal de este trabajo es estudiar la capacidad de 80 revestimientos para fachadas disponibles regionalmente para mitigar los efectos negativos de la Isla de Calor Urbana, mediante la determinacion del Indice de Reflectancia Solar (SRI). El material que posee el comportamiento mas eficiente es el Acrilico Rulato Travertino fino marfil (SRI = 100%, Temp. Sup.= 35 oC), mientras el mas ineficiente es el Acrilico Llaneado fino gris plomo (SRI = 29%, Temp. Sup.= 74 oC). No obstante existen alternativas intermedias que resultan del efecto combinado de la composicion del material, su color y textura. Esta situacion demuestra que es posible mitigar el efecto de isla de calor a partir de una adecuada seleccion de revestimientos verticales.

Pautas de diseño para disminuir las temperaturas urbanas en regiones con alta productividad solar. Parámetros morfológicos y materiales

Noelia Liliana Alchapar; Erica Norma Correa

This study examined the numerical modeling performance of morphological and materials alternatives for reducing urban temperatures. The aim was to identify design and urban regeneration guidelines that enable the densification of residential areas in the city of Mendoza, Argentina. To this end, using ENVI-met 3.1 software 32, scenarios were simulated that combined: different levels of solar reflectance (albedo) of building envelope materials, different urban profile morphologies, the presence or absence of forestation in urban canyons, and E-W/N-S variation in orientation. From the simulation results it can be inferred that there is more efficient thermal performance in the vegetated scenarios that morphologically have a continuous urban profile above the municipal building line. Regarding envelope materiality, there are high albedo levels (0.7) on roofs and pavements, and low albedo levels (0.3) on facades.

Thermal Comfort and Urban Climate Due to the Morphology of Urban Parks in Arid Zones

Related to this last strategy, it is known and documented that trees and green areas contribute significantly to the cooling of our cities and to energy saving (Santamouris, 2001). Trees may provide a solar protection in summer while on the other hand, the evapotranspiration may reduce the urban temperature. At the same time, trees absorb sound and block erosion caused by rains, filter hazardous contaminants, reduce wind speed and prevent erosion.
