This research work focuses on the study of microclimate conditions of two squares of Madrid, a city with a considerable Urban Heat Island. The process includes field measurements of the surface and radiant temperatures of materials on buildings façades, pavements and urban furniture. Air temperature, relative humidity and wind speed and direction were also measured. A virtual 3D model was used for sun exposure and solar radiation simulations. The urban microclimate regulation capacity of the finishing materials and shading are numerically defined. Considering the results obtained from measurements and simulations, a procedure for open spaces’ microclimate variety classification and identification is proposed: An approach to describe the thermal level for open spaces, in order to help the urban designers and planners to provide high microclimate variety for the users to meet their difference thermal demand. This is a key element to identify environmental quality and to obtain thermal comfort.
