A new sustainability assessment method for façade cladding panels: a case study of fiber/textile reinforced cement sheets

Abstract

As the building sector is one of the leading responsible for energy consumption and CO2 emissions, criteria of sustainability, availability, and recyclability should be considered for developing materials even in the envelopes. Façade, as the first element against the undesirable external impact, may contribute to building sustainability by reducing the amount of energy consumption and providing indoor environment quality for the inhabitants. The envelope excluding its aesthetic function should fulfill certain requirements such as strength, flexibility, ductility, lightness, thermal and acoustical insulation, durability, and sustainability. Fiber/Textile cement sheets as an interesting architectural material attract great interest during the last decade, especially those reinforced with more sustainable fibers like vegetables or textile wastes. In this sense, this paper presents a novel model to evaluate the sustainability index of façade cladding panel, especially the fiber/textile cement board. To this end, a new model for assessing objectively the façade cladding sustainability was designed and developed based on MIVES according to the value function concept and seminars of experts.
