Portland State Greenroof Research

So there are many links that belong here pertaining to the subject of greenroof research at PSU, but I'll add those in a later post.
First, let me document some recent visits to some projects on campus, which I now consider current or future pilot sites:
On the SRTC, a study by David Sailor and Todd Rosenstiel about the interaction between greenroofs and photovoltaics (GRiPV)

We have already begun to repurpose some of these modules for a pilot investigating the potential of "urban epiphyte communities" as greenroof plants (ie mosses, liverworts, lichens? etc)

One more recent trip was to a site on top of Cramer Hall where the engineers without borders group has installed several very large modules with different planting depths and materials. It remains to be seen whether useful data can be gleaned from these sites due to some problems with the experimental design. Still, we are considering re-purposing these roofs for a study on greenroofs as habitat....

Last night I did some rooftop agriculture "research" at a place called Noble Rot. Of course I had to sample the menu as well...

I've moved!

I'm an asst. prof at portland state university now! I hold quite a unique position that entails both teaching very specialized courses as part of the urban honors program, mentoring undergraduate research projects, and continuing my studies on green roofs and urban ecology.  More info about the program can be found here:

Green roof temperature

This summer, Paul Ellis, of Montgomery Blair HS will be measuring the temperature above the experimental roofs at UMD in order to determine how different roof treatments might affect the air entering hvac systems and thus the energy demands of these systems...
Here he is installing several temperature sensors at different heights above a platform planted in S. kamtschaticum:

More UMD research

Here's a view of an experiment comparing solar panel function with and without green roof supplementation... ala Scott Tjaden et al.

Low Impact design tour (Baltimore style) ... no greenroofs but some 'interesting' demonstrations...

Data from the umbc greenroof can be found here

Can't wait until it grows in a little more...
