| Abstract/Contents: | Presents the concept of green roofs as a new option for storm water and improved water. States that green roofs "convert thousands of square feet of idle space on rooftops to retention areas". Researchers at North Carolina State University (NCSU) are studying four aspects of green roofs: "1) Storm water runoff reduction, both volume and peak; 2) Water quality, to determine if less nitrogen and phosphorus are leaving green roofs; 3) Plant survival, to see which grow best on green roofs in the Southeast; and 4) Temperature of green roof runoff, to see if it increases or decreases." Describes the three roofs under study. States that "extensive green roof systems are characterized by low weight, lower capital cost, less plant diversity, and minimal maintenance requirements...compared to intensive green roofs." Lists properties to be considered for each type of green roof design and describes the four different methods used by ERTH to distribute its soil mix on rooftops. Presents challenges in green roof growing media installations. Also defines intensive and extensive green roofs, stating that "both intensive and extensive green roofs are good for reducing storm water runoff, although intensive designs are more expensive and are mostly done over parking garages that are heavily reinforced structurally." Includes a composter's view of green roofs, suggesting that "one main benefit from green roofs is quality of life...contributing to [the neighborhood's] livability and aesthetics." In addition, several examples of green roofs in Seattle are provided, including Seattle's City Hall and Justice Center. Profiles Bill Hunt, Assistant Professor in North Carolina State University's Biological & Agricultural Engineering Department, whose "teaching, research and outreach has focused on innovative practices such as...green roofs." Mentions awards presented by the Green Roofs for Healthy Cities organization, including categories such as intensive residential, intensive institutional, intensive industrial/commercial, extensive residential, extensive institutional, and extensive industrial/commercial. |
