Estrategias ambientales en fachadas. Propuesta de intervención en edificio 1C de la Universitat Politècnica de València Environmental strategies on façades. Intervention proposal in building 1C of Universitat Politécnica de València

Construction is one of the priority sectors of the European Green Deal, a field that, despite various innovations in both products and processes, continues to generate a significant environmental impact. The construction sector consumer over 50% of raw materials extracted annually and is responsible for about a third of the total waste produced and approximately 40% of anthropogenic CO, emissions. Green façades, or living walls, have been recognized for their potential in improving the sus- tainability of existing buildings by reducing energy consumption, lowering the environmental footprint, and offering aesthetic and social benefits. This paper presents a proposal for the transformation of the façade of Building 1C at the Universitat Politécnica de Valencia, which currently consists of multilayer phenolic panels. Over time, these panels have shown signs of deterioration and replacing them with a green façade offers a promising solution for enhancing building sustainability. The proposed green façade system aims to improve thermal insulation, reduce solar radiation absorption, and enhance energy efficiency. The system will include modular panels with pre-cultivated substrate to ensure optimal plant growth. This intervention not only contributes to the building's environmental performance but also provides a more pleasant aesthetic and supports urban biodiversity. The paper highlights the technical aspects of the green façade installation process and the potential benefits in terms of energy savings and CO, reduction.
