Abstract


El desarrollo sostenible requiere la consideración de toda una serie de elementos interconectados, como la reducción de la demanda de energía y el consumo de agua, la minimización de los residuos y la contaminación y la provisión de un transporte público eficiente. Bajo ese enfoque de “construcción sostenible”, el cierre de los ciclos de materiales y agua, así como la reducción del consumo energético son los principales objetivos en el sector de la edificación. En este contexto, el concepto de Infraestructura Verde Urbana (UGI) se ha definido como un conjunto de sistemas de construcción creados por el hombre, pero basados en la naturaleza, como techos verdes y sistemas de ecologización vertical. UGI proporciona varios eco-servicios al entorno urbano, como la reducción de la escorrentía superficial en las grandes ciudades, la reducción del efecto isla de calor, el apoyo a la biodiversidad, la mejora de la durabilidad de las membranas impermeabilizantes y el ahorro de energía en los edificios, entre otros. Durante la última década se han llevado a cabo una serie de acciones de investigación en la Universidad de Lleida con el fin de estudiar estos sistemas constructivos, cuantificar sus beneficios y mejorar su diseño. En este trabajo presentamos estos estudios

Abstract

Sustainable development requires the consideration of a whole host of interconnected elements, such as the reduction of energy demand and water consumption, minimizing waste and pollution, and providing efficient public transport. Under that “sustainable construction” approach, the closing of materials and water cycles as well as the reduction of energy consumption are the main objectives in the building sector. In this context, the concept of Urban Green Infrastructure (UGI) has been defined as a set of man-made, but nature-based, construction systems, such as green roofs and vertical greening systems. UGI provides several eco-services into the urban environment, such as the reduction of surface runoff in large cities, reduction of heat island effect, support to biodiversity, waterproofing membranes durability improvement, and building energy savings, among others. During the last decade a series of research actions have been carried out at the University of Lleida in order to study these construction systems, to quantify their benefits, and to improve their design. In this work we present these studies
