Today was our last day working on the roof for this semester. We began installing the rails for the new green wall system. It took a bit for us to get started, because we had to drill into the concrete walls on the roof. We mounted the rails vertically in 6 or so columns. This green wall system is very different from the others that are currently on the roof; this system has a bag inside each module that holds all of the soil and plants for each module, and each module has hooks that hang onto the rails. The location for this new green wall system will ensure that the water runoff does not affect the temperature monitors underneath the nearby green roof system, and it may also get a little less sun than the other walls have been getting.
