Efecto de amortiguamiento térmico de una barrera verde de Arundo donax como elemento de bioclimatización en edificios

Abstract

RESUMENEntre los principales impactos ambientales derivados de la operación de edificios habitacionales está la generación de gases de efecto invernadero resultante del consumo eléctrico de sistemas de climatización. El uso de sistemas de vegetación representa una alternativa para disminuir dicho consumo energético. Las barreras verdes son sistemas de vegetación empleados como protección contra el viento, aunque recientemente se ha explorado su uso como sistemas de amortiguación acústica. En este trabajo se analiza su posible aplicación como sistemas de aislamiento térmico para edificios. En específico, se reporta el comportamiento de una barrera verde de Arundo donax como elemento de bioclimatización. Los resultados se analizan a partir de las temperaturas medidas en el interior y exterior de edificios prototipo, en función de la presencia de una barrera verde. Adicionalmente se determinó la traspiración del Arundo donax en condiciones ambientales extremas.Palabras clave: arquitectura bioclimática; Arundo donax; barrera verde; amortiguamiento térmico. ABSTRACT

Bio‐based building components: A newly sustainable solution for traditional walls made of Arundo donax and gypsum

“…The panel is based on an ancient rural technique, widely diffused in southern Italy, which makes use of Arundo donax L. (A.d.) canes combined with gypsum plaster to build walls and ceilings of rural buildings 11,12 . These building components have good thermal insulation combined with lightweight and easy construction processes 13,14 . The enhancement of the thermal capacity of these panels by means of the introduction in the canes of a natural wax oleogel (WO), that is, a gelator that dissolves in oil upon heating and crystallizes upon cooling absorbing and releasing heat, is proposed in this paper (see Figure 1).…”

A specific experimental campaign, aiming at the comparison of traditional and innovative panels was carried out to assess the enhanced thermal performance of the proposed solution.…”

First record of Melanaphis donacis (Passerini, 1861) (Hemiptera: Aphididae) in México

“…However, A. donax is also used as ornament, raw material for handicrafts, housing construction material, and its suitability as an urban green barrier is being explored (Rodríguez-Salinas et al 2017). Therefore, the impact of M. donacis could be categorized as urban and peri-urban, of uncertain importance even for Mexican artisanal economic activities.…”
