I have an IFC model of a building and need a clear, defensible study that shows which façade windows are hit by direct sunlight between 07:00 and 21:00, March through October. The entire workflow must stay inside SketchUp—the file will come to you already geolocated, or I can supply the exact coordinates and true north so you can set it yourself. Only visual evidence is required. Using SketchUp’s native Shadow Study or a plugin you prefer, generate renderings that make it obvious when sunlight reaches each window. The single decision-making criterion is the specific hours of direct sun a window receives each day; no temperature or percentage calculations are needed. Deliverables • High-resolution stills or an animated shadow sequence for every façade, annotated to show the daily hours of direct sun on each window. • A concise summary sheet flagging any window that exceeds the agreed hourly threshold for shading. Let me know which SketchUp tools you plan to use and how quickly you can turn this around.
