Climate Design Data: Kilkenny, Ireland
How to research climate design data for a specific site in Kilkenny — 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 IE dump](https://download.geonames.org/export/dump/IE.zip) (CC BY 4.0, snapshot 2026-08-31, GeoNames ID 2963398). 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. Climate screening data from the [NASA POWER Climatology API documentation](https://power.larc.nasa.gov/docs/services/api/temporal/climatology/) and [exact point response](https://power.larc.nasa.gov/api/temporal/climatology/point?parameters=T2M%2CT2M_MAX%2CT2M_MIN%2CRH2M%2CPRECTOTCORR%2CWS10M&community=SB&longitude=-7.25222&latitude=52.65417&format=JSON), retrieved 2026-08-31; source period: 20-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2020). NASA POWER values are gridded screening statistics, not code design conditions or guaranteed local observations.
Direct answer
NASA POWER's 2001–2020 climatology at the Kilkenny reference point reports an annual mean 2 m temperature of 9.5 °C and relative humidity of 89.4%. The highest monthly maximum is 26.6 °C in August, while the lowest monthly minimum is -7.2 °C in January; these are screening statistics, not code design temperatures. The point response uses LST and the 20-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2020); its annual corrected precipitation is 2.78 mm/day and annual 10 m wind speed is 5.18 m/s. For climate design data, use the 26.6 °C and -7.2 °C monthly extrema to screen seasonal exposure, then obtain the adopted percentile design conditions. NASA POWER is gridded climatology: verify elevation, microclimate, urban exposure, station or weather-file suitability, current code edition and the authority's required source before design use.

What must be verified for Kilkenny?
Kilkenny is represented here at approximately 52.6542, -7.2522 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 climate design data 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 climate-design-workflow page is a project-starting worksheet, not a design value or approval. The controlling authority and qualified professionals for the Kilkenny site remain authoritative.
Which related searches does this primary location record cover?
This primary route consolidates the location evidence needed for Climate Design Data, Weather File Guide, Overheating Weather Data, Building Climate Checklist. A narrower route should be released only when it adds a materially different official source, calculation, process, threshold or worked example.
