Vegetation influences on the human thermal comfort in outdoor spaces: criteria for urban planning

This work addresses one of the most important questions in ecological engineering to do with cities: it is something which interests engineers and architects and, more generally, all those whose duty it is to make decisions on urban planning. A methodology is put forward relating green zones with the environmental comfort of a city since, after establishing this relationship, one can start to formulate comfort indices quantifying green zones for each zone or district of a city.
