• Unpacking Park Cool Island Effects Using Remote-Sensed, Measured and Modelled Microclimatic Data (2025) · Land · cited 9× · doi

  The difficulty of measuring the Park Cool Island effect in a way that is relevant to human thermal comfort. The challenge of generalizing the results to different park typologies and urban contexts. The need to consider multiple factors, including tree canopy cover, urban design, and microclimatic conditions, when assessing the effect.

• The unequal contribution of urban blue-green space to the cooling effect (2025) · Frontiers in Environmental Science · cited 6× · doi

  The current understanding of the contribution of urban blue-green spaces to the cooling effect is limited. There is a need to examine the relationship between blue-green spaces and LST in different regions. The study aims to fill this gap by providing a thorough evaluation of the cooling impact of blue-green spaces on surface temperature and its regional variations.

• Impacts of Vertical Greenery on Outdoor Thermal Comfort and Carbon Emission Reduction at the Urban Scale in Turin, Italy (2025) · Buildings · cited 13× · doi

  There is a need to investigate the effect of green walls on air temperature, Tmrt, and outdoor thermal comfort. There is a gap in understanding the contribution of green walls to reducing carbon emission intensity. The study aims to fill this gap by evaluating the impact of green walls on urban heat islands and carbon emission reduction.
