The Republik Building/ Xero Flor America HQ Green Roof
Durham, NC, USA

2,343 sf. Greenroof


Project Description & Details

In July 2012, Xero Flor America (XFA) moved into renovated offices in The Republik Building at 211 Rigsbee Avenue in downtown Durham, N.C.’s historic district. The new 2,343 square-foot Xero Flor green roof atop the building, completed in February 2013, is the first green roof installed on a historic building within the boundaries of the district. Alterations to the roof cover required a Certificate of Appropriateness from the Durham Historic Preservation Commission.

The XF301+2 system option was selected for the project. Fully saturated, it weighs only 10-11 pounds per square foot, making it ideal for the retrofit. XFA showcases three of its plant palettes on the roof: Appalachian Plant Mix, Southern Plant Mix, and the Mid-Atlantic Plant Mix. Given its size and the specific Xero Flor option installed, the green roof atop the Republik Building/ Xero Flor America HQ can prevent more than 50,000 gallons of stormwater runoff annually. And, it demonstrates that properly planned and installed green roofs can be compatible with historic preservation.
