Children are building a cooler city that is better adapted to heat

You’ve probably already noticed: our climate is changing! Extreme weather such as heat waves become more severe and more frequent. During summer, these heat waves can lead to higher temperatures in cities compared to rural areas. This is called the urban heat island effect. In short, between the concrete and the asphalt you feel the heat more, especially at night! High temperatures and heat stress can lead to health problems. But what would happen if we converted all the car parks into parks?

With the LEGO urban climate game, you are the architect of the future. Build your miniature city with LEGO, and with the help of artificial intelligence, you can immediately see the impact of buildings, greenspace and water on the temperature. Can you make your neighbourhood cooler and better adapted to heat?

I Love Science Festival

We were once again at the I Love Science Festival, held in Brussels from 10 to 12 October 2025. This edition drew around 17,000 participants, and our WATS ambassador Lesley De Cruz had the honour of being the festival’s “godmother” this year. As always, our LEGO temperature boxes were a big hit. Many children designed their own climate-resilient city in LEGO and immediately saw the impact of their choices on the local temperature, learning in a playful way about the link between land use and urban heat....

I Love Science Festival

With the support of Innoviris, we were able to significantly upgrade and expand our workshop for this edition of the I Love Science Festival. The 4 beautiful new LEGO temperature boxes attracted a lot of attention and participants. Many children were able to design their climate-resilient city in LEGO and immediately visualize the impact on temperature. Through the creative process of building and testing, children learn about the impact of land use on the temperature in their city....
