Designing Green Roofs for Hurricane Impact

June 10, 2021  |  12:00 PM ET 


Green roofs are not yet approved for the Florida Building Code by the Florida Building Commission (FBC) because there is concern that they are vulnerable to high, speed wind velocity damage and transport. Through a grant from FEMA and  the FBC, two UF researchers in landscape architecture and engineering conducted full scale outdoor trials to research the effects of hurricane force winds on green roof assemblies. Built  in place and modular trays were planted with a variety of species and subjected to incremental winds up to 120 mph. Pull out tests were also performed to learn anchoring qualities of plants.

Learning Objectives:

  • To learn how hurricane force winds affect roofs and green roof assemblies
  • To learn about UF's full scale trials to research the impacts of wind uplift on green roof assemblies
  • To learn the results of plant material selections' performance in the research trials
  • To learn how design decisions can limit  the effects of high velocity wind uplift and the impacts upon green roofs
  • To provide for an opportunity for attendees to ask questions and share information

    This course is will provide 1.5 Continuing Education Credits

    Meet The Speaker:

    Glenn Acomb

    Senior Lecturer Emeritus

    Department of Landscape Architecture

    University of Florida

    Glenn Acomb, FASLA, split his career in professional practice and teaching at the University of Florida’s Department of Landscape Architecture.

    At UF, he taught extensively in design and construction studios, and focused on sustainable site design and stormwater-based green infrastructure research.  In 2009, he co-authored the Florida Field Guide for Low Impact Development (IFAS, 2009), as well as advising the preparation of national green design standards for the National Association of Home Builders, the U. S. EPA’s WaterSense program, and the Florida Green Building Coalition.  In 2012 and 2013 his student teams won back-to-back national EPA competitions for green infrastructure, the “Campus RainWorks Challenge”.

    Among his publications is LARE Review: Mastering Section C Site Design (PPI, 2007), the first book to aid in preparation for the LARE, and he has served as an instructor in FLASLA’s LARE Prep Courses for the past 20 years.

    In 2007, he co-designed one of the first green roofs in Florida, UF’s 2,600 square foot, extensive green roof which served as research laboratory for his classes.  He also conducted cutting-edge research in the effects of hurricane wind uplift on green roof assemblies for FEMA and the Florida Building Commission.

    He holds a BLA from Louisiana State University and an MLA from Harvard University's Graduate School of Design.

    Lead in promoting healthy and just communities through the design and stewardship of our natural and built environment.
