- Data source: Location data from the [GeoNames HK dump](https://download.geonames.org/export/dump/HK.zip) (CC BY 4.0, snapshot 2026-08-31, GeoNames ID 12719430). Regulatory starting point: [Hong Kong Buildings Department](https://www.bd.gov.hk/en/resources/codes-and-references/codes-and-design-manuals/index.html). 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.

## Key facts

| Fact | Value |
| --- | --- |
| Location reference | 22.4248, 114.0358 (GeoNames ID 12719430; replace with surveyed project coordinates) |
| Administrative area | NYL (GeoNames snapshot code; confirm the competent local jurisdiction) |
| Regulatory starting point | Buildings Ordinance, subsidiary regulations, codes of practice, and practice notes (country-level context only; identify the competent local authority) |
| June-solstice solar-noon check | 89.0° (declination-only geometry; not an hourly obstruction model) |
| Equinox solar-noon check | 67.6° (declination-only geometry) |
| December-solstice solar-noon check | 44.1° (declination-only geometry; verify civil time and horizon) |
| Approximate daylight range | 10.6–13.4 hours (representative 21st-day geometry (December to June); excludes refraction and terrain) |

## Direct answer

For Shap Pat Heung at 22.4248, 114.0358, the declination-only solar-noon altitude is approximately 89.0° at the June solstice, 67.6° at an equinox and 44.1° 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 12719430 in administrative area NYL, at 22.4248, 114.0358; replace it with the surveyed parcel point before relying on the result. As a transparent geometry check, declination-only solar-noon altitude is about 89.0° at the June solstice, 67.6° at an equinox and 44.1° at the December solstice. Representative 21st-day geometry ranges from about 10.6 hours in December to 13.4 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 daylight and building orientation record.

## What must be verified for Shap Pat Heung?

Shap Pat Heung is represented here at approximately **22.4248, 114.0358** 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 daylight and building orientation 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.

| Input | Project-specific evidence | QA question |
| --- | --- | --- |
| Site | surveyed coordinates, elevation and horizon | Does the point represent the building? |
| Weather/solar method | named dataset, algorithm, period and time basis | Are station, time zone and units explicit? |
| Design scenario | current and future scenario agreed by the team | Is an average being mistaken for an extreme? |
| Compliance | adopted local document and edition | Was applicability confirmed with the authority? |

## What are the limits of this worksheet?

This daylight-workflow page is a project-starting worksheet, not a design value or approval. The controlling authority and qualified professionals for the Shap Pat Heung site remain authoritative.

Harth computed the Shap Pat Heung fingerprint for latitude 22.4248° with the Cooper declination approximation, `90° - |latitude - declination|` at solar noon, centre-to-centre sunrise hour angle and `1 / tan(altitude)` shadow ratio. Longitude 114.0358° is retained for a later civil-time conversion; this screen does not perform that conversion. See [NOAA's solar calculation details](https://gml.noaa.gov/grad/solcalc/calcdetails.html). Atmospheric refraction, terrain, facade azimuth and obstructions remain outside this first-pass comparison.

## Sources and method

Location data from the [GeoNames HK dump](https://download.geonames.org/export/dump/HK.zip) (CC BY 4.0, snapshot 2026-08-31, GeoNames ID 12719430). Regulatory starting point: [Hong Kong Buildings Department](https://www.bd.gov.hk/en/resources/codes-and-references/codes-and-design-manuals/index.html). 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.
