文摘
The typical membranes for building are polymer-based materials, which have origin from fossil fuel. Nevertheless, they are supposed to become very lightweight building components, compared with other typical ones, and, due to their lightness, involve fewer stiffening structural materials (bio-based or not) than other traditional massive components. The need of understanding their real potentials and limits in terms of eco-efficiency is declared. The paper presents the research results about the eco-efficiency principles in the field of membrane architecture, based on the application of Life Cycle Assessment methodology to membrane structures. The paper presents a systematic review of the state of the art, with the aim to demonstrate the advantages of the Life Cycle Design strategy answering to the environmental sustainability. A comparison matrix about existing environmental data on membranes (environmental impacts, EPD, Recycling and up-cycling processes) and the LCA studies are part of the shown research output. On the need of harmonization of the research about the availability of LCA data for membranes and on the basis of the collected information, a first set of eco-design principles for membranes structures is proposed. Concluding, the authors reveal the current gap between the research studies and the real praxis in architectural design referred to a specific context and envisage further improvements of the application of the eco-efficiency principles starting from the early design phases.
