The design of open space in the city is primarily based on systems of relationships that, in the case of public space, often do not deal with physical elements of a specific shape, volume, size. It is a space composed of air, and underground infrastructure running through green elements, fences and thresholds. These elements are often not visible, but offer quality, liveable urban spaces. The complexity of energy and environmental phenomena demands an integrated approach to their analysis and resolution. The environmental/architectonic section seems to be the most appropriate tool. It should be used in a repetitive, continuous mode throughout the urban area, along with environmental cross-sectional tomography, in order to manage urban project requalification. Tomography is a method of exploring a phenomenon through a large number of perspectives. The sections, repeated at close range, explore deep into and above the earth, measure distances and heights, determine relationships between what is immaterial and material and define the intrinsic qualities of individual objects. Environmental tomography applies this approach to the study of urban areas and can be considered a methodology of diagnostic practice for a new environmental strategy. In this paper, a preliminary evaluation of this new approach to planning is considered and some case studies are presented using a 3-D numerical simulation model (namely ENVI-met), which is able to extrapolate cross sections and evaluate the microclimate in urban structures and open spaces.

Abstract
The design of open space in the city is primarily based on systems of relationships that, in the case of public space, often do not deal with physical elements of a specific shape, volume, size. It is a space composed of air, and underground infrastructure running through green elements, fences and thresholds. These elements are often not visible, but offer quality, liveable urban spaces. The complexity of energy and environmental phenomena demands an integrated approach to their analysis and resolution. The environmental/architectonic section seems to be the most appropriate tool. It should be used in a repetitive, continuous mode throughout the urban area, along with environmental cross-sectional tomography, in order to manage urban project requalification. Tomography is a method of exploring a phenomenon through a large number of perspectives. The sections, repeated at close range, explore deep into and above the earth, measure distances and heights, determine relationships between what is immaterial and material and define the intrinsic qualities of individual objects. Environmental tomography applies this approach to the study of urban areas and can be considered a methodology of diagnostic practice for a new environmental strategy. In this paper, a preliminary evaluation of this new approach to planning is considered and some case studies are presented using a 3-D numerical simulation model (namely ENVI-met), which is able to extrapolate cross sections and evaluate the microclimate in urban structures and open spaces.
