- Image AI generatedIn 2018, a University of Hawaii study in Honolulu found that a planted green roof could stay noticeably cooler than a conventional white roof, particularly during the hottest part of the day.
- The research compared an existing white rooftop with a green roof covered in sedum plants, recording temperatures at the roof surface and in the air above it over 36 consecutive days.
- The results showed a clear difference: the green roof’s average daytime surface temperature was 4.1°F lower than that of the white roof, while its peak temperature was 18.5°F lower.
