Sun Path: Srinagar, India

How to research sun path for a specific site in Srinagar — the controlling authority, source documents, and checks to run before you rely on a number.

Last updated August 31, 2026 · Location data from the [GeoNames IN dump](https://download.geonames.org/export/dump/IN.zip) (CC BY 4.0, snapshot 2026-08-31, GeoNames ID 1255634). Regulatory starting point: [Bureau of Indian Standards and the applicable state or urban local body](https://www.services.bis.gov.in/php/BIS_2.0/bisconnect/knowyourstandards/Indian_standards/isdetails/). Figures are illustrative — verify against the current locally adopted edition for the site.

Direct answer

For Srinagar at 34.0857, 74.8055, the declination-only solar-noon altitude is approximately 79.4° at the June solstice, 55.9° at an equinox and 32.5° at the December solstice. Refine these geometry checks with the project date, civil time, facade azimuth, terrain and local horizon. The reproducible location record is GeoNames ID 1255634 in administrative area 12, at 34.0857, 74.8055; replace it with the surveyed parcel point before relying on the result. As a transparent geometry check, declination-only solar-noon altitude is about 79.4° at the June solstice, 55.9° at an equinox and 32.5° at the December solstice. Representative 21st-day geometry ranges from about 9.7 hours in December to 14.3 hours in June; this excludes atmospheric refraction, terrain and obstruction effects. The cited national authority is a discovery starting point; current local documents and a named qualified reviewer control project use of this sun path record.

What must be verified for Srinagar?

Srinagar is represented here at approximately 34.0857, 74.8055 for discovery and workflow planning. A project address, parcel, elevation, exposure, authority, and submission date must replace that city-centre reference before design use.

How should sun path be established?

  1. Fix the surveyed site and local time basis.
  2. Select an authoritative weather source or a named solar-position algorithm.
  3. Record period, percentile or scenario and units.
  4. Test sensitivity to elevation, exposure, urban form and horizon.
  5. Save the source file, retrieval date and checker in the model record.

What are the limits of this worksheet?

This sun-path-workflow page is a project-starting worksheet, not a design value or approval. The controlling authority and qualified professionals for the Srinagar site remain authoritative.

This primary route consolidates the location evidence needed for Sun Path, Solar Altitude & Azimuth, Solar Shading Design, Daylight & Orientation. A narrower route should be released only when it adds a materially different official source, calculation, process, threshold or worked example.
