Sun & Solar

Three views of solar exposure across the property, built from a bioclimatic design study of local weather and sun-position data.

Computed with the NOAA solar-position algorithm (declination + equation-of-time series, ±0.01° accuracy) for the site's exact coordinates. Times are local clock time (EST in December, EDT in March/June/September). Azimuth is measured clockwise from true north. Cross-checked against the site's SunCalc-derived solstice figures in the Lesson 3 sector-analysis report — solar noon altitude and sunrise/sunset azimuth agree within ~1°.

Sun Path — 3D Site Diagram

The same 4 seasonal sun paths as the aerial overlay, shown as true arcs through the sky above a simplified isometric model of the site — house, camper, chicken coop, pool, and the major trees, at their real relative positions and sizes.

Site massing: real footprints and positions from the Sector Compass base map (house, camper, chicken coop, pool, and the largest trees within the parcel), converted to feet using the base map's own scale bar and rotated to true north-up. Sun-path data: NOAA solar-position algorithm at the site's exact coordinates, same series as Sun Path Charts and Sun Path Overlay. Projection: standard 30° isometric — building heights and tree canopy sizes are reasonable estimates, not surveyed; arc geometry (sun azimuth/altitude) is exact.

Sun Path Overlay

Where the sun actually tracks across this specific yard, by season — plotted directly onto the site's aerial photo — plus a full annual reference chart from the University of Oregon Solar Radiation Monitoring Laboratory's Sun Chart Program for the site's exact coordinates (41.57°N, 72.65°W).

Seasonal Sun Arcs Over the Site

Anchored near the main growing area, north-up aerial photo — arc direction (azimuth) is exact; arc radius is schematic (winter drawn furthest out, summer closest in, echoing how low winter sun reaches deep into a yard while high summer sun stays more overhead) — not a literal shadow-length prediction.

21st of every month, 10-minute resolution · polar projection (center = directly overhead, edge = horizon) · faint radial lines mark 2-hour intervals on the spring equinox, matching the official UO SRML chart for this exact lat/lng.
