From a research lab to a company

Climate studies of wind, heat and sun often take days or weeks. So the climate stays out of the room where people decide on a design. We started infrared.city to change that.

The engine began as research at the City Intelligence Lab of the Austrian Institute of Technology in Vienna. There, the team trained the first machine-learning models that predict wind and sun in seconds instead of hours.

The research had a name: InFraReD, an intelligent framework for resilient design. For three years the team published it in journals, books and at conferences: real-time solar radiation, fast wind prediction, and design optimisation for wind comfort and sun.

In 2023 the founders took the research out of the lab and founded Infrared City GmbH, to bring it into daily design work. The team brings architects, environmental engineers and software engineers together.

  1. 2020First paper

    InFraReD, an intelligent framework for resilient design, is first published at CAADRIA in Bangkok.

  2. 2021Real-time solar

    A deep-learning model predicts solar radiation in real time.

  3. 2022Fast wind

    Fast wind prediction for city planning, and "The InFraRed Revolution" in Architectural Design.

  4. 2023Founded

    Infrared City GmbH is founded in Vienna. Pre-seed of about €1M, led by Xista Science Ventures.

  5. TodayOne engine

    API and SDK, plugins, the web platform and city twins. More than 2,500 accounts use it.
