Abstract

GIS tool to estimate the urban solar radiation
Track: Renewable Energy
Authors: Fabio Oliosi, Claudio Carneiro, Gilles Desthieux

A general understanding of the solar admittance and solar gains incident on the urban fabric is relevant to assess the potential implementation of renewable energies at the scale of the city. The authors propose a tool that uses LIDAR data to automatically derive this information in a fast way with no need to refer to the construction of complex models of the urban layout/geometry. Very few applications have been implemented in order to process LIDAR data for the environmental analysis and to get an understanding about the performance of the urban form. Yet, the increasing interest in the quantification of energy-based indicators at the scale of the city, strongly suggests the integration of 3-D GIS and urban studies in order to provide useful applications for the urban planning. Aim of the work is to establish a conceptual method and tools to calculate yearly input of irradiation on roofs of buildings.
