Could Sensors Help Green Roofs Grow?
Just as wireless sensor networks increasingly are helping building owners and tenants keep track on energy efficiency and water conservation inside, they are also at the center of several new research projects that aims to build a better understanding of their performance.
The main feature of a green roof is native vegetation that has three jobs to do other than look pretty: provide better insulation against the elements, absorb and collect rainwater, and mitigate the heat island effect often caused by dark roofs. They are usually with a foundation structure and different layers for drainage and protection from the sun.
Over the next two years, both sections will be wired up with dozens of sensors and a weather station as part of a two-year research project with the Portland State University Green Building Research Laboratory.
