ASITIS, together with the City of Slavkov u Brna, has won first place in the national Czech Smart City Awards 2025 in the category Urban Planning and Environment. The award recognizes a data driven analysis of the 3+30+300 rule that helps cities plan greener, healthier and more climate resilient public spaces.
The joint project of Slavkov and ASITIS clearly demonstrates how a city can use data driven urban greenery planning to strengthen climate resilience and support a healthier environment for its residents.
The awarded project focused on a full scale analysis of the 3-30-300 rule for Slavkov u Brna and provided the city with actionable insights for tree planting, heat mitigation and strategic development of public green spaces.

What the 3-30-300 rule is and why it matters for modern cities
The 3-30-300 rule is one of the most widely adopted international guidelines for effective green infrastructure planning. It outlines three simple but powerful principles:
Rule 3-30-300
3 trees
30 % canopy
300 meters
The rule helps cities quickly identify where greenery is sufficient and where it is missing. Trees are one of the most effective natural tools for cooling urban areas, reducing heat islands, improving air quality, enhancing biodiversity and supporting mental and physical health. As heatwaves intensify across Europe, the 3-30-300 rule is becoming an essential framework for climate adaptation in cities.
How ASITIS conducted the 3-30-300 analysis in Slavkov u Brna

The analysis examined tree visibility, canopy coverage, shading of public spaces and walking distance to green areas. These data sets were transformed into interactive map layers, a detailed report, visual infographics and a clear list of recommended actions for the city.
The results highlighted both strong and vulnerable areas. Many residents benefit from greenery close to their homes, while other districts lack shade and require targeted planting, street redesign or creation of new parks.

What this means for Slavkov and why it inspires other cities
The project strengthens the city’s microclimate, improves thermal comfort and supports the well being of residents.
The case of Slavkov shows that even smaller municipalities can work with top level geodata and advanced analytics.
The 3+30+300 methodology is fully scalable and ready for rapid deployment in other cities across Europe. ASITIS has already delivered similar analyses for Dublin, Ede, Lisbon and several Czech municipalities.
