A sustainable approach for the refurbishment process of vernacular heritage: the Sesga house case study (Valencia, Spain)

Abstract

The refurbishment of traditional vernacular architecture is currently of interest for the conservation of heritage, historic landscape and cultural landscape, as well as for its potential benefits in the field of environmental sustainability. The carefully selected materials and techniques used in the refurbishment of a traditional dwelling in Sesga (Valencia, Spain) maintain the local construction techniques while causing the least possible environmental impact, saving on transport and transformation and construction energy. This article uses LCA to showcase this contribution, examining three scenarios: the first option is the refurbishment of the case study using natural traditional materials and techniques; the second presents a hypothetical refurbishment using widely used industrial materials; and a third option looks at the demolition of the existing building and the addition of a new construction with widely used industrial materials. This comparison has shown where and why the first option is, broadly speaking, the most sustainable option in environmental, sociocultural and socioeconomic terms.
