Solar Shading Design: Kilquade, Ireland
How to research solar shading design for a specific site in Kilquade — the controlling authority, source documents, and checks to run before you rely on a number.
Last updated September 2, 2026 · Location data from the [GeoNames IE dump](https://download.geonames.org/export/dump/IE.zip) (CC BY 4.0, snapshot 2026-08-31, GeoNames ID 7870988). Regulatory starting point: [Department of Housing, Local Government and Heritage and the local building-control authority](https://www.gov.ie/en/department-of-housing-local-government-and-heritage/collections/building-standards/). 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 Kilquade at 53.0974, -6.0841, the declination-only solar-noon altitude is approximately 60.3° at the June solstice, 36.9° at an equinox and 13.5° 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 7870988 in administrative area L, at 53.0974, -6.0841; replace it with the surveyed parcel point before relying on the result. As a transparent geometry check, declination-only solar-noon altitude is about 60.3° at the June solstice, 36.9° at an equinox and 13.5° at the December solstice. Representative 21st-day geometry ranges from about 7.3 hours in December to 16.7 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 solar shading design record.

What must be verified for Kilquade?
Kilquade is represented here at approximately 53.0974, -6.0841 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 solar shading design be established?
- Fix the surveyed site and local time basis.
- Select an authoritative weather source or a named solar-position algorithm.
- Record period, percentile or scenario and units.
- Test sensitivity to elevation, exposure, urban form and horizon.
- 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 shading-workflow page is a project-starting worksheet, not a design value or approval. The controlling authority and qualified professionals for the Kilquade site remain authoritative.

Kilquade overhang sizing hand check
P:H is projection depth divided by the vertical facade distance to shade, calculated as 1 / tan(solar altitude). For a 1.20 m vertical target, multiply the table ratio by 1.20 m. The 09:00 and 15:00 columns use apparent solar time and show the solar-profile-plane ratio; they do not resolve facade azimuth, horizontal shadow displacement or a side-fin geometry.
The Kilquade worksheet uses latitude 53.0974° and records longitude -6.0841°. A project study must replace the reference point, use the actual facade normal and obstruction mask, convert to civil time, test the full occupied period and account for diffuse sky, glazing and thermal performance. Refine solar positions with the NREL SPA.
