05 Sun Shadow

Main Components

Canopy
Vegetation that attenuates the sun instead of blocking it, with an optional leaf-on/leaf-off season. Feed the Canopy input of Sun Hours or Solar Irradiation.
Facade Grid
Analysis points with outward normals and per-cell areas over surfaces, at a spacing suited to a building rather than a district.
Sun Path
Daily sun arcs, analemmas and sun positions as curves and points — north-aware, drawn from the same solar geometry the sun studies use.
Sun Vectors
Sun positions for a period at a chosen time step (6-minute and finer), from site and clock rather than from an EPW's hourly rows.
Shadow
Lit or shaded at each analysis point for one or more sun instants — the shadow's position, not accumulated sun hours.
Solar Irradiation
Cumulative incident solar energy per point in kWh/m² — beam plus isotropic sky plus ground reflection. An interactive preview, not a Radiance simulation.
Sun Hours
Direct sun hours and shadow by ray casting — an interactive preview, not a Radiance simulation.
Sun Stats
Area-weighted min/mean/median/max over a sun result, plus the area and fraction reaching a threshold.
Sunlight Compliance
EN 17037 sunlight exposure and BRE amenity overshadowing / APSH against a sun-hours result. Design aid — thresholds are editable and not certified.
