Modeling Urban Heat Island with the UWG
A guide to using urban-scale Dragonfly models to morph EPW files to account for the Urban Heat Island (UHI) effect using the Urban Weather Generator (UWG) simulation engine. The resulting urban EPW files can be used to assess the impact of UHI on building energy use, outdoor thermal comfort, and passive survivability.
Check out the Introduction page to find sample files used in this video.
