Location: Raleigh, North Carolina

Description:  Although LRI did not install the initial green roofs at the Duke Smart Home, we were contacted to replant the roofs after a severe drought and lack of maintenance resulted in the loss of the majority of vegetation. Plant plugs included species of Sedums, Delosperma, Sempervivum. Seeds were also cast of Talinum and Allium. In addition to the replanting, Living Roofs, Inc. installed an irrigation system which uses 100% rainwater from two large cisterns. A maintenance program was also initiated to ensure the establishment and on-going performance of the green roof. The green roofs are only one of many innovative features at the Smart Home which received LEED Platinum certification. They can be seen in their entirety at: Duke Smart Home.
