2023, in Vienna, Austria. A spin-off of the City Intelligence Lab, Austrian Institute of Technology (AIT)

Headquarters

Gumpendorferstrasse 91/1/12, 1060 Vienna, Austria

Product

One climate simulation engine: API and SDK, plugins, the web platform and live layers for digital twins

Users

More than 2,500 accounts. 3.20M+ simulations computed, our own studies and stress tests included

Speed

About 5 seconds for 1 km² (geometry already uploaded). 400 km² of Berlin in 44 seconds (four 100 km² runs in parallel; perceived heat (UTCI), one summer day, 1 m, end to end)

Funding

Pre-seed round of about €1M in 2023, led by Xista Science Ventures, with 2bX, Antler, Heartfelt and P3A Ventures

Research

16 peer-reviewed papers, 2020 to 2025: the methods behind the engine and their practical application in design and planning

Story angles

• Heat in citiesStreets in the same city can feel very different. The engine shows which streets, squares and facades get the most heat and the most sun, hour by hour.
• The live layer, city by cityHong Kong is the public example: heat-stress forecasts for the next 72 hours, every hour, at metre scale. We prepare your city the same way.
• Street-level heat for eventsReplay a marathon or event route kilometre by kilometre: heat, sun and headwind exposure.
• Checked against field dataWe compare the engine with field measurements of radiant heat (Tmrt) at four sites, two of them held-out, and report the errors next to SOLWEIG, a widely used research model. The results are on the validation page.

For your story

• Validation How the engine compares with field measurements and with SOLWEIG.
• When to use which tool How infrared.city compares with other climate and energy tools.
• Infrared Core The engine: speed, resolution and how it scales to whole cities.
• The live layer Heat-stress forecasts for the next 72 hours, with Hong Kong as the public example.
• Company story From the City Intelligence Lab to a company, with the founders.
• For cities Cities and operations: heat, comfort and safety across a district or a whole city.
• For buildings and architects Design and real estate: compare options early, with heat, wind and sun on the model.
• For software platforms Maps and digital twins that add climate results through the API.
