We analyzed landcover change in Porto, Portugal, using satellite imagery from 2017 and 2022. K-Nearest Neighbor classification revealed increases in impervious surfaces and decreases in vegetation, highlighting opportunities for green roof interventions and the importance of climate justice considerations.

Green roofs and photovoltaic arrays can coexist, enhancing biodiversity and solar energy generation. In a simulated study, pollinator plants thrived better under PV arrays due to favorable microclimate conditions, suggesting benefits for urban habitat diversity and plant establishment.

Green roofs can sequester carbon dioxide, but their contribution is often overlooked. Plants on green roofs allocate more biomass below ground to cope with stress and benefit from symbiotic fungi. This suggests green roofs significantly aid in carbon sequestration.

This paper evaluates carbon sequestration on green roofs. Results suggest shallower beds with native grasses may offset deeper beds, aiding climate mitigation with proper irrigation.

This study aims to describe the integration of green wall technologies and a tunnel ventilation facility, and models the potential ambient air quality improvement the green wall plants have through PM2.5 dry deposition.

This study repurposes automotive sheet metal into 300 modular living wall system (MLWS) planters, observing the cooling effects of 25 plant species on southeast-facing MLWS during summer. Results show Coreopsis lanceolata 'Sterntaler' achieving a 3.4 °C cooler ambient air temperature, highlighting MLWS's notable cooling effects in humid subtropical climates.

Discover how lettuce cultivation thrived on a shallow substrate, overcoming temperature extremes and low fertility. Learn about the impact of fertilizers and weather conditions on crop productivity.

In this study, 21 green roof tables were constructed and utilized to compare nine green roof treatments including a roof water reservoir designed to provide temporary water storage (blue roof), two commercially available module systems, these module systems combined with a blue roof underneath (blue-green roof), rockwool, pavers, gravel, and the roofing membrane alone.
