Solar envelope as criteria for density and verticalization in urban planning

Abstract

In general, our cities continue to grow wildly, with the neighborhoods around their centers pressured to use changes and land use, being upright and dense without proper planning, committing the access of the buildings to the sun and natural light. This work proposes the application of solar envelope as input for determination of regulatory forms of consolidation and vertical integration, and aims to verify the potential of this device as possible criterion of solar guidelines for the urban environment, applied to the control of land use, compression neighborhoods, occupation of urban voids, the suburbs, the new centers and small towns. Solar envelopes were generated on land of various sizes and orientations facing streets with different widths. We adopted the Rhinoceros software with Grasshopper and Diva applications for the generation of solar envelopes. Its constructive potentials were analyzed, and for the results obtained, it was found that it is possible to ensure the lots and buildings access to the sun. It is concluded that the use of solar envelope, as a strategy alternative for the development of projects for the urban subdivision and for buildings, serves to recommend solar guidelines for urban planning.
