the timeline 

October 2011:
  • Hydrotech visits Chadwick Arboretum to show us their green roof system.  Stop in Howlett Hall rm 139, (the future site of the project) and check out the green roof model on display - courtesy of Hydrotech.  
  • Let's build a test plot!  Several of our students constructed green roof plots to compare two of the leading local media mixes as well as the success rate of sedums over the winter when planted as late in the season as October.  Check us out on Facebook for photos and updates.

July - August 2011:
  • Schematic and Development Phase, The Green Roof Team (compiled of the architect, engineer, OSU facilities, faculty and students) meets twice a month to complete the design for the green roof.  This detail includes several options, as the final outcome will be dependent on the funds we raise.  

May 2011: 

March  2011:
  • This past March, Ohio State interviewed 5 Architect/Engineer firms for the replacement of the roof and Green Roof design at Howlett Hall.  We are pleased to report that CTL Engineering with NBBJ Architects were hired for the job.   Congratulations Team! 

Summer  2010:
  • On  August 24, 2010, we received news from OSU Facilities Operations and Development: The Howlett Hall roof replacement has been approved for use of bond funds.  (Our blighted roof will be replaced!)
  • Electronic Leak Detection:  Friday, July 23rd, 2010 at 12pm, Howlett Hall rm 119;  Presentation by engineer Laura Kozel with Plant America Green, Boston, Massachusetts to discuss electronic leak detection options. 

Winter 2010:
  • Chadwick Arboretum has hosted several 'lunch and learn' programs with national green roof companies Garland, Live Roof, Derbigum, Sarnafil and Tremco to discuss various installation methods and materials.  In February 2010, we hosted a full-day design charrette with over 100 participants from regional architect and engineering firms, environmental professionals, students, faculty, landscape architects, etc.  As a result of the charrette, we have six basic design concepts.
  • Schematic Design:  Landscape Architects John Woods and Ed Michelson from NBBJ in collaboration with Landscape Architect Jerry Smith of Smith\GreenHealth Consulting, LLC participated in our design charrette and are continuing the schematic design development with OSU's Steve Volkmann and Rick Van-Deusen.  Graphics available upon request!   Michelson and Woods also designed the rain gardens at Jenning's Hall, and Grange Insurance office in Columbus, OH.   
  • Fund-raising  Our Green Roof Leadership Team is actively seeking funding opportunities to allow us to implement this green roof at Howlett Hall.  We have applied for several grants through the Ohio EPA.   Although the Arboretum is in the Department of Horticulture and Crop Science, it is funded only in part by The Ohio State University.  It is through the generous support of the community that ensures this project and many others come to fruition.  For donor information, please visit  http://giveto.osu.edu/greenroof or contact Mary Maloney at maloney.23@osu.edu
  • Research: Collaborating with students in the Construction Management and Horticulture departments to take part in a national pilot project that will compare the performance of native plant species on a green roof from various ecosystems around the country; California, Phoenix, Ohio and TX.   The Ohio Bioproducts Innovation Center, OSU Depts. of Geography, FABE, Civil Engineering, Entomology, and others have been engaged to include heir research on the Howlett Hall Green Roof.
