I need to estimate hourly solar irradiance on building envelopes (one value - average solar irradiance of all the walls and the roof) for each building in the urban neighborhood. Any geospatial technique/tool which I understand that annual solar irradiance could be captured in terms of sun hours, not on a building level but at the pixel level using Rhino-Grasshopper. However, I am not sure how the hourly value can be adopted offers this? A suitable reference is estimated for a complete year for all the buildings in an urban neighborhood. Any thoughts would be highly appreciatedappreciated.
