- Data source: Original calculation using latitude 40.7128° N and declinations +23.44°, 0°, and -23.44°. Formula: altitude = 90° - |latitude - declination|. Time zone: America/New_York. Verify occupied-hour positions with the NOAA Solar Calculator; values omit refraction, equation of time, terrain, obstructions, and facade azimuth.

## Key facts

| Fact | Value |
| --- | --- |
| Latitude | 40.7128° N (New York, NY) |
| June solstice noon | 72.7° (south at solar noon) |
| Equinox noon | 49.3° (geometric solar noon) |
| December solstice noon | 25.8° (geometric solar noon) |

## Direct answer

Calculated solar-noon angles and a first-pass fixed-shading worksheet for New York, NY, using transparent solar geometry rather than an unexplained chart. A key reference is latitude: 40.7128° N; check the cited source, edition, units, and applicability before using it for design, compliance, procurement, or approval. Latitude is 40.7128° N; New York, NY. June solstice noon is 72.7°; south at solar noon. Equinox noon is 49.3°; geometric solar noon. Projection ratio = 1 / tan(solar altitude). Multiply the ratio by the vertical distance the noon shadow must cover. Use this only as a hand check before a full-year study. Read the values with the cited source, edition or observation period, units and applicability; replace illustrative inputs with current project evidence before design, procurement or approval use.

## Which solar conditions control the result?

| Date | Declination | Altitude | Projection / vertical shade distance |
| --- | ---: | ---: | ---: |
| June solstice | +23.44° | 72.73° | 0.311 |
| Equinox | 0° | 49.29° | 0.861 |
| December solstice | -23.44° | 25.85° | 2.064 |

Projection ratio = 1 / tan(solar altitude). Multiply the ratio by the vertical distance the noon shadow must cover. Use this only as a hand check before a full-year study.

## New York, NY shading record

Record facade azimuth, window head and sill, overhang height, required shaded dates and hours, coordinates (40.7128° N), time zone (America/New_York), calculation method, surrounding obstructions, reviewer and date. Compare the full model against the three noon ratios above and retain screenshots of the critical summer and shoulder-season hours. Verify hourly positions with the [NOAA Solar Calculator](https://gml.noaa.gov/grad/solcalc/).
