Decisions teams make with infrared.city

Which tower option stays comfortable, when a site crew needs shade, which street trees cool a square. Each case runs on our simulations, and you can try it in your browser.

Built by architects, engineers and scientists in Vienna

infrared.city started at the City Intelligence Lab of the Austrian Institute of Technology in Vienna. Our team turns years of simulation research into tools people use every day.

Live behind this text: the Hong Kong climate twin, sun hours on every facade, updated every hour. We prepare your city the same way.
