This commercial building issituated within a brownfield redevelopment andincorporates a number <strong>of</strong> green building features,such as rainwater storage <strong>for</strong> toilet flushing andoperable windows. The 30,000 square foot greenro<strong>of</strong> was completed in the summer <strong>of</strong> 2002 and per<strong>for</strong>ms multiple functions withinthe building. The 28 acre site was redeveloped with a design goal <strong>of</strong> reducingnon-point source pollution in order to protect the Gwynns Falls Watershed, theInner Harbour <strong>of</strong> Baltimore and ultimately Cheaspeake Bay. It was also designedto provide the developer with an opportunity to attract and retain tenants, such asthe Maryland Department <strong>of</strong> the Environment. The system can be viewed fromseven floors above but is not designed <strong>for</strong> occupant access. It was constructedas an inverted membrane assembly using a single ply PVC membrane over whichlies four inches <strong>of</strong> poly-iso insulation board, and 3 inches <strong>of</strong> growing medium separatedby two geotextile filter fabrics. The plants are comprised <strong>of</strong> 12 differentdrought tolerant sedum species that will show well throughout the year. The ro<strong>of</strong>was designed <strong>for</strong> minimal maintenance requirements and has no permanent irrigationsystem. The green ro<strong>of</strong> generates energy efficiency benefits, will extendthe longevity <strong>of</strong> the membranes, and reduces the urban heat island and annualrun<strong>of</strong>f by an estimated 50% to 75%. The first extensive green ro<strong>of</strong> in Baltimore,this project provides a great opportunity to raise awareness <strong>of</strong> the multi-functionalbenefits <strong>of</strong> green ro<strong>of</strong> infrastructure.<strong>Green</strong> <strong>Ro<strong>of</strong></strong> <strong>Awards</strong> <strong>of</strong> <strong>Excellence</strong> Chicago 2003
