Mr. Toad doesn't care to reinvent the wheel.
Last Thursday and Friday Jorg and I subjected ourselves to the horrendous Baltimore - DC traffic and attended the The First Annual Mid-Atlantic Green Roof Science & Technology Symposium at the University of Maryland. The title of the symposium was "Redefining Green Roof Science" and the mission statement clearly states why:
Standards for green roof performance have not been established. The MGRST symposium is dedicated to disseminating results of scientific research that will lead to the establishment of green roof performance standards for the Mid-Atlantic region.
Year after year we attended similar academic conferences and each year we are confronted with the same experiments and the same conclusions, all of which we know have been done and confirmed a decade ago in Germany. For us, the researchers are only confirming what we believe to already be ‘common sense.’ We are certainly not disparaging the work of researchers who are attempting to better understand the green roof field they have recently entered. What we truly regret is the inability of academic researchers to acquire and process the information already available rather than attempting to reinvent the wheel.
What the green roof industry needs from its academic partners is a strict methodology and process to assess all the green roof components / complete systems available on the market. Nearly a decade ago, the Green Roof Media Testing Laboratory was successfully implemented at Penn State University and has undoubtedly beneficially impacted the green roof industry. A similar manufacture’s test for all other green roof components would best serve the entire green roof industry by setting minimum requirements and disabling inferior products from being dumped on the market.
