Abstract
Compared to the traditional materials, textile membrane and foil structural enclosures use minimal quantity of materials to cover spaces or close façades, thanks especially to their tensioning ability, by shaping themselves to the forces ways, with a few additional stiffening components. However the environmental compatibility, due to their actual fossil fuel origin, together with the thermal, optical, and acoustic performances are crucial factors to be verified during the design phase. The need of understanding their potentials and limits in terms of eco-efficiency is on the debate. Starting from these concepts, the aim of the research is to demonstrate the advantages of the Life Cycle Design strategy answering to the environmental sustainability of membrane building components.The authors found out two eco-efficiency principles for the application of membranes and foils, orienting the designers towards a more sustainable whole life spanned lightweight technology’s choice. The main advancement of this research is presented adding new ETFE membranes case studies to the initial analysis (Monticelli, Zanelli, 2016). The aim of this ex-post application of the principles on built examples is the demonstration of their validness for the designer’s need and the intention is to spread their use during the early design stage. The calculation on a wider and different use of membranes allowed to sketch benchmark reference rates. The results of the data analysis show how lightweight technologies offer a high degree of freedom in shaping geometries and forms, while only their optimized application can guarantee a sustainable and LCA effective result.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
