| description | Fetch Open-Meteo archive weather at any vibe22 site lat/lon and write an EnergyPlus AMY EPW as {slug}_amy_*.epw. Practice pack: Lakeside / sp_creekside. Use when AMY is missing, stale, or the user asks for actual-year weather. |

Honesty
| File | What it is | What it is not |
|---|
{slug}_amy_*.epw | AMY = Open-Meteo actual year at site lat/lon (M&V) | Not TMY. Not "typical." |
Site *TMY*.epw | Typical year (download separately) | Not auto-built from Open-Meteo |
*screening*.epw / Chicago O'Hare | Screening stand-in only | Never auto-pick as TMY |
Do not build an EPW from BAS OAT-only. EnergyPlus needs dry-bulb, dewpoint,
RH, pressure, GHI/DNI/DHI, and wind. Open-Meteo archive supplies those.
Agent tool
Geo comes from {site}/eplus/assumptions/answers.json or campus (lat, lon,
data_window). Window end extends to Open-Meteo archive lag (~3 days behind
today) unless you pass --end. slug = site_slug() (campus_id or folder).

Writes:
eplus/weather/{slug}_amy_YYYYMM_YYYYMM.epweplus/weather/open_meteo_amy_hourly.csveplus/weather/amy_meta.json (source=open-meteo-archive, kind=AMY_OPEN_METEO)
Skips the network if the existing AMY already covers (today − 5 days).
--force refetches. Old dated AMY files are pruned; Chicago screening is never
copied. Historical practice files may still be named madison_amy_*.epw.
When to run
- Live DSM / GL14 and no
*_amy*.epw
- Existing AMY ends before the BAS / requested sim window
- User asks for fresh Open-Meteo / actual-year weather
Do not
- Fetch TMY from Open-Meteo (wrong product)
- Copy
USA_IL_Chicago* or *screening*.epw into the TMY slot
- Invent solar/RH/wind from the interval meter
- Invent lat/lon when campus/answers lack them
- Point Streamlit file pickers at weather (pack ingest + this tool only)
