Infrared City — the climate intelligence layer for buildings and cities

A design prototype. Not the live site.

One page, rebuilt around one argument: run the same site twice and read the difference. The data under it is real measured Hong Kong simulation output.

Not finished The hero film and the section-01 explorer are still in work — camera, look, interaction. The 45 floors of daylight, facade solar, ground heat and wind beneath them are measured results.
Heavy The scene is about 40 MB. On a slow line the first frame takes seconds.
One page, many audiences The button at the bottom right (I am…) switches the persona: hero calls to action, the questions the live layer asks, the door marked for you. In production the URL does this (?icp=…).
Prices are the verified current plans — except Pro, which is under review. Do not quote it outside the company.

01 · What it is

Climate you can measure,
before anything is built.

We simulate the climate around and inside buildings — wind, heat, sun and daylight — at metre resolution, in seconds. One site below. Pick a scale, pick an analysis: every number is read off the model, nothing is a picture of one.

SOLVE 0.8 S

How much daylight actually reaches a desk on this floor, once the neighbours block the sky. Resolved floor by floor.

Everyone else ships an application. We ship the capability — so a product, a practice or a city becomes climate-aware without hiring a simulation team.

BUILD IT YOURSELF

A CFD team, hired and kept.
A training set you must collect and defend.
A GPU cluster that idles between projects.
Validation, argued paper by paper.
Years before the first answer.

One call. A field back in seconds — tiling, polling and merging handled for you. You get a result, not a job queue to babysit.

REST API OGC-compliant. Call it from any language or stack.
Python SDK Five lines to a result.
AI-agent skill One-click install for Claude Code, Cursor, Copilot, Windsurf.

# pip install infrared-sdk
from infrared_sdk import Client

client = Client(api_key)
run = client.run_area(
    polygon=aoi,
    analysis="thermal-comfort")

heat = run.result()   # → a field, in seconds

Fast, and honest about it.

Run it twice. Read the difference.

Same site, same engine, two wind directions. Drag the divide: each side is a real run, and the number on the line is the measured difference between them.

LOADING MEASURED WIND RUNS…

Model	Measured against	Status
Thermal comfort	2–4 K RMSE on temperate built-up scenes, no per-site calibration	Validated
Wind	Benchmarked against AIJ wind-tunnel measurements	Screening
Daylight sky model	Byte-for-byte identical to the Radiance reference	Exact
Per-model studies	Underway; a consolidated overview is in preparation	In progress

35-tile district

Tiles run in parallel — a district costs barely more time than a single site. Timings are typical and vary with connection.

Screening-grade. Good enough to compare options and find problems — not a certified measurement. We say so because it is what makes the rest trustworthy.
