Sun Path: Kuala Terengganu, Malaysia

How to research sun path for a specific site in Kuala Terengganu — 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 MY dump](https://download.geonames.org/export/dump/MY.zip) (CC BY 4.0, snapshot 2026-08-31, GeoNames ID 1734705). Regulatory starting point: [the applicable state and local authority](https://jkt.kpkt.gov.my/). Figures are illustrative — verify against the current locally adopted edition for the site. Solar-method context: [NOAA Solar Calculation Details](https://gml.noaa.gov/grad/solcalc/calcdetails.html); the Harth monthly table uses a simpler declination and geometric-daylight approximation whose stated limitations must be retained.

Direct answer

For Kuala Terengganu at 5.3302, 103.1408, the declination-only solar-noon altitude is approximately 71.9° at the June solstice, 84.7° at an equinox and 61.2° 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 1734705 in administrative area 13, at 5.3302, 103.1408; replace it with the surveyed parcel point before relying on the result. As a transparent geometry check, declination-only solar-noon altitude is about 71.9° at the June solstice, 84.7° at an equinox and 61.2° at the December solstice. Representative 21st-day geometry ranges from about 11.7 hours in December to 12.3 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 Kuala Terengganu?

Kuala Terengganu is represented here at approximately 5.3302, 103.1408 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 Kuala Terengganu 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.

Harth computed the Kuala Terengganu fingerprint for latitude 5.3302° with the Cooper declination approximation, 90° - |latitude - declination| at solar noon, centre-to-centre sunrise hour angle and 1 / tan(altitude) shadow ratio. Longitude 103.1408° is retained for a later civil-time conversion; this screen does not perform that conversion. See NOAA's solar calculation details. Atmospheric refraction, terrain, facade azimuth and obstructions remain outside this first-pass comparison.
