Project Vega-Chopera: a constructive-structural system based on poplar wood

Abstract

This article presents the development of an innovative structural system using poplar wood from the Vega (meadow) of Granada, through the design of an architectural project. The proposed system is based on the progress made by the LIFE Wood for Future project at the University of Granada, which explores the use of poplar wood as a structural material, both alone and in conjunction with other materials such as black pine, concrete, or laminated steel. The interdisciplinary collaboration between the universities of Granada and Santiago de Compostela has been key to accomplish the practical way of resolving the design of the Vega-chopera architectural project through a load-bearing structure for a large-surface building with large spans and flexible use. Beyond addressing technical obstacles stemming from the innovative system proposed, the project integrates design advantages derived from the natural behaviour of poplar groves, as it allows the transfer of inherent bioclimatic strategies, such as solar capture, natural ventilation, and humidity control. The aim is to offer an adaptable, versatile structural system based on poplar wood which also allow future projects to benefit from the strength, flexibility, and lightness of this innovative structure. This research pursues to strengthen the local economy, reduce the carbon footprint in construction, and preserve the poplar groves of the Vega as heritage spaces. © 2025 Universidad Politecnica de Valencia.
