The use of 3D GIS to analyse the influence of urban context on buildings' solar energy potential

摘要

Buildings are responsible for 40% of energy consumption and 36% of Co, emissions in the European Union. To bring these levels down, governments are striving to promote a more efficient use of energy resources and an increase adoption of renewable energy technologies, as photovoltaic panels and solar collectors on the building envelopes. To fully exploit the potential of these technologies, a detailed analysis of the incident solar radiation on buildings roofs and facades is mandatory taking into account the geographical and urban environments.
