Reads an EnergyPlus Weather file and turns it into a climate brief: what the climate is, the numbers that matter, and a ranked list of what it asks of the building. Every finding links to the chart that proves it.
Everything runs in your browser from the weather file itself. There is no AI call and nothing is gated.

Using it
Load a climate file
Pick a station on the map or drop your own .epw. A OneBuilding .zip adds the STAT and DDY sidecars, but design conditions no longer need them — they come from the weather file's own header.
Read the brief
The climate named and classified, six headline numbers, a twelve-month strip showing when the building is under pressure, and design findings ranked by how strongly the data supports them. Each finding states a result, an action, and the measurement behind it.
Check the evidence
Four sections, organised by design question rather than by data type: heat and cold, sun and sky, wind, and water and humidity. Each opens on a single chart that answers the question, with the remaining charts behind More detail.
The hero of the heat section is the bioclimatic chart: the year's hours plotted on psychrometric axes against the comfort band, so you can see how far the climate sits from comfort and in which direction it misses.
Take it further
Open the same station in Sun Path, Daylight, U-Value, Urban Wind, PV or Site Studio. Copy the link, or print the brief.
Ask the advisor
Optional. The advisor discusses the findings and challenges them against your scheme. It never gates them.
Sharing a station
The station, layer and section all live in the address bar, so a link reopens exactly what you were looking at:
/architool/epw?station=401790&layer=evidence§ion=heatThat makes it usable in a studio brief or a class handout.
What the numbers rest on
- Comfort is ASHRAE 55 adaptive comfort, with the 80% acceptability band. Hours outside the standard's stated validity range are reported as out of scope rather than graded.
- Design conditions come from the weather file's own ASHRAE header. Percentiles of the file's 8760 rows are shown alongside them, labelled separately, because they are a different claim.
- Sun positions honour the station's timezone, so azimuths are correct rather than rotated by fifteen degrees per hour of UTC offset.
- Wind rose sectors follow meteorological convention, centred on their compass bearing.
- Seasons are derived from the file's own monthly temperatures, so southern-hemisphere stations are not analysed upside down.
- Köppen classification needs rainfall. Many TMYx files omit it, and the dashboard says so rather than guessing.
Tips
- Do — Start on the Brief. The charts are there to check a finding, not to be read end to end.
- Do — Use the closest station to your site; a city often has several.
- Avoid — Mixing TMY (typical year) and AMY (actual year) files in the same comparison.
