Urban pervious concrete for thermal conditioning in open spaces: an adaptation to the climate change and the urban heat island effect.

Abstract

UIA CartujaQanat project is part of a new vision of the urban environment, in which the way of thinking about cities and their spaces is changed, as well as in the interaction of its inhabitants with them. In this new concept of urban space, possible solutions to current and future needs, both social and climatic, must be found, since these environments have the responsibility to contribute to improving the lives of their inhabitants by minimizing the consumption of resources used in it. These solutions are the result of the knowledge gained from experience and tradition together with innovation and research.

The project incorporates passive techniques and bioclimatic solutions adapted to the hot and dry climate of the city of Seville, which is where it is located, trying to create semi-confined open spaces that provide a comfortable environment. The solutions adopted introduced water as a heat transfer fluid that allows these spaces to be tempered. Apart from other solutions such as bioclimatic lattices, we worked on draining pavements that, thanks to their permeability, allow the flow of water and the evaporation of air through their surface.

In this work the study of the use of pervious concrete flooring solutions and their advantages over the use of other materials is developed. Analysing its behaviour in its combination in hybrid pavements with vegetal soils or with fines such as silica sand, as well as other solutions that allow a constructive solution that reduces the temperature of the pavement using the evaporative effect, with minimal maintenance and cost.
