A simulation platform for urban energy systems, born at ETH Zurich. It automatically gathers geographic data on buildings and streets, computes hourly energy demand for every building in a neighbourhood or city, assesses solar, geothermal and sewage-heat potential, and designs and optimises district heating and cooling networks. It lets you compare low-carbon technology scenarios. It suits architects, urban planners and energy engineers in early design stages. An interface for Grasshopper is also available.
