Lightweight and quickly assembled: the most eco-efficient model for architecture

Abstract

For over 20 years, we have followed a line of research that seeks to propose models for architecture which minimize the environmental impact caused by both its construction as its use. We understand that, in order to reduce the environmental impact produced by current constructions, it is necessary to change the way they are designed and built. The followed process has been firstly focused on the search for geometries constructed with adequate materiality which would provide effective architectural solutions with a minimum consumption of material (lightweight solutions). Secondly, we have experienced quick assembly and disassembly procedures (deployable mesh, modular systems, etc.) that reduced the assembly time of the proposed systems and, therefore, will minimize the impact (quick assembly/reversibility). Finally, it has been possible to relate the proposed models (lightweight, quick assembly and reversible) with tools for lifecycle assessment which allow accurately assess the environmental impact of them. The use and development of LCA tools has allowed us to optimize the proposed models. In addition, in the described process, original parametric control tools (geometry and processes) have been used. They allow to particularize the proposed models to each case based on their possibilities of manufacture. The way followed by several made works, which are applications of the proposed models, will be described then.
