Listing
Paste details from a StreetEasy listing (or anywhere). We don't scrape the URL — it's saved for later. Address lookup uses NYC GeoSearch and DOITT building footprints (2D horizon, no 3D raytrace).
Window faces — each side has its own glass; they add up in the score. Click a host wall on the plan to place that face’s windows (not just the midpoint). Hover a side: + adds a face, × removes it. Inset / reveal is how far the glass sits behind the outer wall (~30 cm typical; 0 = flush).
Try a preset:
Footprint sides (click to aim the selected face, same as clicking the plan):
2D sun-blockage profile (azimuth 0° N → clockwise). Taller bars = higher horizon.
Top view · north up · click the host wall where the windows sit. + / × pins add or remove faces.
Nearby building photos (Wikimedia Commons — not the listing, just the block).
Sun score
Breakdown:
Typical day · year-average W/m² by clock hour, with sky-view and the inset/reveal you set. Hollow bars ignore nearby buildings.
Average sun power through the glass · hour of day × left/right angle (looking out). Darker = more blocked or off-axis.
