Water and Plants for Wet, Mesic, or Xeric Green Roofs

This article explores several seasoned green roofs where designers selected plants for their preferences for wet to dry habitats. Plants that thrive in wet, mesic, or xeric (dry) conditions can be employed on green roofs to perform a range of integrated building functions such as energy conservation, micro-climate mitigation, or cleaning of wastewater.

Cooling the Urban Heat Island

Sustainable Futures: Designing Green Communities and Buildings is an all new biweekly podcast from Green Roofs for Healthy Cities featuring interviews and discussions about the innovative approaches to green infrastructure, resilience planning, and sustainable design. Dr. Brad Bass explores one of the most direct manifestations of climate change, the urban heat island - what it is, how it works, and what can be done about it.

Disentangling Dynamics of Green Roof Vegetation Analogue to Dry Grassland Over 3 Years: Plant and Substrate Response to Microenvironmental Variations

The abiotic conditions of the ExGR substrate are analogous to those of native dry grasslands (poor, shallow and highly drained soil), providing opportunities for diversifying ExGR with native flora. This study characterized vegetation and substrate dynamics of a sown native dry grassland community on a 254 m² ExGR in relation to microenvironmental conditions.

Designing Green Roofs for Biodiversity

Thoughtful green infrastructure projects, including green roofs and living walls, are one important strategy to provide crucial habitat in cities. Although many specifics vary by region and climate, there are several basic things to consider when designing for biodiversity on green roofs and other green infrastructure.

Improving Stormwater Retention on Green Roofs

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.
