Vegetation development on extensive vegetated green roofs: Influence of substrate composition, establishment method and species mix
Technology for establishment of vegetated roofs (green roofs) has developed rapidly over recent years but knowledge about how these systems will develop over time is still limited. This study investigates vegetation development on unfertilised thin extensive vegetated roofs during a 3-year period. The vegetation systems investigated were designed to be low maintenance and had a saturated weight...
متن کاملCarbon sequestration potential of extensive green roofs.
Two studies were conducted with the objective of quantifying the carbon storage potential of extensive green roofs. The first was performed on eight roofs in Michigan and four roofs in Maryland, ranging from 1 to 6 years in age. All 12 green roofs were composed primarily of Sedum species, and substrate depths ranged from 2.5 to 12.7 cm. Aboveground plant material was harvested in the fall of 20...
متن کاملlichens on extensive green roofs : evapotranspiration , Cladonia
Green roofs are constructed ecosystems that provide ecosystem services in urban environments. Shallow substrate green roofs subject the vegetation layer to desiccation and other environmental extremes, so researchers have evaluated a variety of stress-tolerant vegetation types for green roof applications. Lichens can be found in most terrestrial habitats. They are able to survive extremely har...
متن کاملEvaluation of Energy Savings for Buildings with Green Roofs Having Different Vegetation
Thermal benefits of different green roof samples were analyzed and compared. Experimental data from ongoing green roof projects was used in a theoretical analysis of air-conditioning energy savings with different green roof applications. Thermal data was collected from a typical non-reflective (EPDM) roof membrane and model green roof systems with three types of growth media (lava, arkalyte, an...
متن کاملThe Role of Extensive Green Roofs in Sustainable Development
As forests, agricultural fields, and suburban and urban lands are replaced with impervious surfaces resulting from development, the necessity to recover green space is becoming increasingly critical to maintain environmental quality. Vegetated or green roofs are one potential remedy for this problem. Establishing plant material on rooftops provides numerous ecological and economic benefits, inc...
