Eficacia de estrategias de disminución del calentamiento urbano. Estudio para una ciudad de clima árido
espanolLas ciudades modifican los parametros microclimaticos aumentando el calentamiento urbano; en virtud de ello, existen diversas estrategias que colaboran a disminuir este impacto en contextos aridos.

期刊介绍:
Founded in 1948 by the Instituto Técnico de la Construcción y del Cemento, Informes de la Construcción is a scientific journal issued quarterly. Its articles cover fields such as architecture, engineering, public works, environment, building services, rehabilitation, construction systems, testing techniques, results of research on building components and systems and so forth. Journal"s readership includes architects, engineers and construction companies, as well as researchers and professionals engaging in building construction and public works.
