Achieving Results: The Science of Successful Green Roofs March 3, 2008 at the Willard InterContinental Hotel, Washington D.C.
AIA /CES (HSW) Learning Units: 4.0
Each spring, Roofscapes, Inc. presents a technical green roof seminar in which we review the latest developments in the industry. This year we will be holding our seminar in Washington, D.C. Our featured speaker this year, is Dr. Erik Ristenpart who wrote the R-WIN computer program, which is used widely in Germany to assess the contribution of green roofs and other best management practices in managing storm water runoff from new developments.
Sun, Wind, Light and Rainfall (and elbow grease) Charlie Miller, Roofscapes, Inc.
Mr. Miller summarizes observations of over 50 green roof projects, some of them now 10 years old. He focuses on the influence of microclimatic factors in determining outcomes and on the critical role of maintenance.
10:15
Role of Plants in Achieving Green Roof Performance Dr. Berghage, Green Roof Research Center, Pennsylvania State University (also representing the Agricultural Analytical Services Laboratory)
Dr. Berghage discusses the role of plants in achieving the sought-after benefits of runoff management and energy modulation in green roofs. He also addresses the importance of material testing and project monitoring.
11:00
Predicting Energy Benefits Dr. Brad Bass, Centre for Environment, University of Toronto
The Institute for Environmental Studies has successfully implemented a subroutine for the ESP-r that allows the influence of green roofs to be incorporated in building envelope energy modeling. Dr. Bass discusses his conclusions about energy benefits in a variety of settings and addresses the challenges in conducting energy modeling of green roofs.

Interactive Site-Wide Stormwater Modeling (FEATURED SPEAKER) Dr. Erik Ristenpart, IFS-Hannover
IFS-Hannover has developed an interactive computer program that allows green roofs to be evaluated in combination with a wide range of related Best Management Practices, including infiltration measures, rainwater harvesting and reuse. This approach involves long-term simulations to generate statistical outputs using local rainfall data. Dr. Ristenpart demonstrates the program using rainfall data from Washington, D.C. He also describes how this type of modeling has been used by municipal authorities in Germany.
1:15
Role of Irrigation in Green Roof Design Charlie Miller, Roofscapes, Inc.
Irrigation plays an important role in many green roof projects, especially when energy benefits are an important design objective or where native plant assemblages are desired. Base-level irrigation techniques offer efficient, low-maintenance options. Mr. Miller presents a variety of applications of base-level irrigation.
2:00
Break
A chance to talk to the speakers and increase both your green roof IQ and blood sugar levels.
2:30
Living Walls Michael Furbish, Furbish Company
Living walls offer a sustainable solution for building climate control and air filtration. Mr. Furbish discusses the principles of interior living wall design and presents an exciting case study of a project his firm has installed in the Washington, D.C area.
2:50
What Lies Below Steven Gordon, PPSI
Mr. Gordon presents waterproofing solutions for a wide range of green roof situations.
3:10
Accountability in Green Roof Design and Implementation Charlie Miller, Roofscapes, Inc.
This session focuses on material testing and includes an overview of a valuable product certification program. Mr. Miller also presents field-tested solutions for projects facing challenges from high wind velocities and steep pitches.
3:30
Green Roof Policy and Regulation in our Region Melissa Muroff, Esq., Roofscapes, Inc.
Ms. Muroff addresses the practical side of implementing cost effective programs that foster the use of green roofs and other Best Management Practices in our region.
