How it works

A consultant looking over your shoulder

Most analysis tools assume you already know what sDA, ASE or U-value mean. ArchiTool doesn't. It is built so a third-year student can drop in a first model and walk away understanding the design better — and so a practice can answer the client's question the same afternoon.

Step 01

Drop the model in

A Rhino .3dm or an IFC from Revit or Archicad. ArchiTool reads the rooms, the windows and which way the building faces — no scripts, no Grasshopper, no setup.

Step 02

Read the result, not a spreadsheet

Results land as a colour map on your floor plan and a few plain sentences: “this room is too dark”, “the south façade overheats in July”. The standards (sDA, ASE, U-value) sit in tooltips for when you want them.

Step 03

Change it and run again

Widen a window, rotate the block, swap the glazing — see the new answer in seconds and iterate as fast as you sketch. Backed by LEED v4.1, ASHRAE 90.1 and ISO 6946, so the numbers are the ones your consultant would use.

Start with the question

Six questions every project asks, answered from one model.

Four in the browser (and in the Rhino panel), two inside Revit. Each one is free to try; the wider toolkit of 16 tools follows below.

Daylight

How much natural light reaches each room?

A daylight map of every floor from the massing — LEED-style sDA and ASE per room, glare-prone zones marked, a one-page PDF and the grid back into Rhino.

Sun Path & Shadow

Where do the shadows fall, hour by hour?

Animated sun path over your model for any date, shadow coverage and sun-hours per façade, shadow outlines out as SVG, DXF or Rhino curves for the planning set.

Sun position checked against NREL's Solar Position Algorithm

Climate Dashboard

What does this site's climate actually ask for?

Pick the city or drop an .epw. Temperature, humidity, sun, wind and rain side by side, comfort hours, and the passive strategies that matter — before a line is drawn.

Urban Wind

Is the plaza sittable, or a wind tunnel?

Street-level wind comfort from your massing, solved on your own GPU in the browser. Annual comfort map at pedestrian height, gust safety check, 3D flow per direction.

Rhino → Revit

Can the concept model become the BIM model?

A layered .3dm becomes native Revit walls, floors, roofs, columns, beams, openings and terrain. Review what each object will become in 3D first, then send it.

Add-ins

The same tools, inside the software you already open.

One ArchiTool account, one plan. A dockable panel in Rhino runs the analyses on the model that is open and bakes the results back as geometry; a ribbon tab in Revit turns the model into native elements and drawings.

ArchiTool for Rhino

Rhino 8 · in testing

A dockable panel that reads the open model.

No export, no upload, no re-import. Pick the layers in the panel, run, and the result lands on named layers in your document — sun and shadow, solar and PV, daylight, site context, panelised SubD.

  • Site Context Generator — The surrounding city, as Rhino geometry.
  • Terrain Analysis Lab — Find where water runs and balance your cut/fill.
  • Sun Path & Shadow Lab — See where shadows fall, hour by hour.
  • Sky Mask Analysis — Measure how much sky a point can see.
  • Solar Radiation — Map kWh/m² on every surface of your model.
  • PV Analysis — Size a rooftop PV array and its yearly yield.
  • Daylight Analysis — Check sDA, ASE and glare at design stage.
  • Rhino → Revit — Turn a .3dm into a native Revit model.

AI Advisor

Ask the consultant grounded in your run.

When a daylight analysis finishes, click Ask the Advisor. It reads your actual rooms, answers in plain English and suggests specific changes to try — by name, with the numbers from your simulation.

  • ✓

    Every number comes from your run

    It looks metrics up with read-only tools against your latest result. Nothing is made up; if it estimates the effect of a change, it tells you to re-run to confirm.

  • ✓

    Explains the jargon as it goes

    Ask “what is sDA?” and get one paragraph in plain English with the LEED threshold for context. An advisor, not stamped engineering.

Which rooms are too dark?
Two rooms are below the LEED 55% sDA target: Bedroom (31%) and Study (42%). The Bedroom's north window is small for the floor area. Want me to estimate the change if you widen it 30%?
Yes — and does this pass LEED?
Checking LEED v4.1 compliance…
Widening the Bedroom window 30% should lift sDA into the 55–65% range — likely a pass. Across the project, 3 of 5 rooms currently meet LEED's threshold. Re-run to confirm the new number.

Compare

How does this compare?

The specialist tools are powerful, but they assume you're already an expert, they need a plugin and a host licence, and they cost like enterprise software. ArchiTool keeps the rigour and drops the friction.

FAQ

Questions

Which tools are free, and which need Pro?

Every tool is free to try, with a clear limit per tool — so you can sanity-check the whole toolkit before paying anything. Free accounts get 5 Daylight runs and 5 Wind runs a week, the basic U-Value library, Site Context up to 500 m, and 3 shop-drawing sheets in Revit. Pro removes the limits: unlimited runs, the full material library, 16 wind directions with CAD export, unlimited sheets, Showroom share links, epJSON export and the AI Advisor. Watermarks come off all exports too. Students get the analysis tools unlimited with a verified academic email.

What is ArchiTool for Revit? Does it need admin rights?

A free Windows installer that adds one ArchiTool.ai tab to Revit 2026 with Rhino to Revit, Drawing Styles and Opening Shop Drawings. It installs into your own user add-ins folder, so no admin rights and no IT ticket. You sign in once with your ArchiTool account; the first three shop-drawing sheets are free, then it's Pro.

Is there a Rhino plugin?

Yes. ArchiTool for Rhino is a dockable panel for Rhino 8: the tools read the model that is open, and results come back as geometry on named layers — no export, no upload. It ships through Rhino's Package Manager as an update to the 01A_Architool package and uses the same account and plan as the site. You don't need it to start: the browser tools read a .3dm directly.

What is the AI Advisor — does it just make stuff up?

No. The Advisor is a chat panel that opens after your daylight analysis finishes. It calls read-only tools against your actual run to fetch room metrics, definitions and LEED v4.1 compliance — every number it quotes is pulled from your simulation, not generated. If it estimates the effect of a design change, it always tells you to re-run to confirm. It's an advisor, not stamped engineering. The Advisor is a Pro feature; the calculator tools stay free.

I've never run a daylight or thermal analysis before. Will I be lost?

No. ArchiTool is built for that exact moment. You drop in a model, see a colour map of your floor plan, and read sentences like “this room is below the recommended daylight level — try a larger window facing north.” The technical terms (sDA, U-value) appear in tooltips you can hover when you're curious — but you don't need them to use the tool.

Is this only for finished designs?

The opposite — it's most useful in early concept and schematic design, when you can still change things. Use it to test “what if I rotate the building?” or “what if I add a courtyard?” while it's still cheap to change your mind. Then, when the design settles, the Revit add-in carries it into production.

How does the student plan work?

Free educational license. Create an account, then confirm your academic email (.edu, .ac.uk, or another university domain) from your account page. The analysis tools are then unlimited at no cost; the AI features stay Pro-only and exports carry an educational watermark. The license lasts a year and renews when you confirm you're still studying — graduate and your projects come with you.

Do I need Rhino?

Rhino is the easiest input (just drop in a .3dm file), but you don't need a Rhino licence to use ArchiTool. You can also import IFC — so models from Revit, Archicad and other BIM tools work too.

How does this compare to ClimateStudio, Honeybee, or Sefaira?

Those are powerful tools for specialists who already know environmental analysis. ArchiTool is for the rest of us — architects and students who want fast, defensible feedback without learning a new language. For deep-physics validation studies, keep using Radiance.

Where does the computation run? Is my model uploaded?

The analysis tools compute in your browser, on your machine — daylight and wind run on your GPU — and the model is not sent to our servers to do it. Two things you choose do leave your machine: publishing a Showroom share link stores that model with us so the link works, and sending a result to Revit passes it through our bridge to your add-in. Nothing else is uploaded.

Can I cancel anytime?

Yes. Cancel any time from the Stripe customer portal. Your account stays on the free tier — your past analyses are not deleted.
