  1. Fieldston Green Roof & Scientific Sensor Installation August 17th, 2007

  2. Overview • Two Green Roofs: 1 upper roof, not accessible to students, with sensors (~5600 sf); 1 lower roof accessible to students (~1500 sf) • Green roof installer: Town and Garden • Fieldston Educator in Charge: Peter Mott • Sensor Design Plan: S. Gaffin, C. Rosenzweig & L. Parshall (Columbia University) • Sensor Installation: Victor Cassella (Brookhaven Natl Labs), Stuart Gaffin (Columbia University), Reggie Blake (City Tech) • Lower Roof Native Plant Design Plan: Matt Palmer (E3B Columbia University)

  3. Upper roof before medium and sensor install ‘Geotextile’ cloth to prevent medium from moving downward Below geotextile is sequentially down: (1) drainage mat; (2) insulation; (3) root penetration barrier; (4) waterproof membrane

  4. 1 of 2 sensor stands: completed stands include 3 buried thermistors; soil moisture probe surface IR temperature sensor, near-surface air and RH sensors.

  5. Medium in sacks and crane to hoist to roof

  6. Hoisting medium onto roof

  7. Raking medium out to uniform 4-inch depth 4-inch depth pipes guide raking

  8. Shoveling and raking in rooftop summer heat … (Central Park high temp that day was 87o but higher up here … )

  9. Weather station tripod stand Surface canvas to ballast medium and plants later …

  10. Weather station mounting weight (~100 lbs on each foot of tripod)

  11. Weather station Albedometer Sensor mounting stands

  12. All sensors are wired to datalogger

  13. Albedometer Albedometer will measure real time albedo of green roof during all times of day and during different seasons (support for meter will be painted black …)

  14. Lower ‘teaching roof’ has an average depth of 8-inches & will be shaped into Intricate topography to study different micro-environments. Native plants will be installed on Sept 17 under Matt Palmer supervision

  15. Lower roof, boundary planting flags demarking different test plots for natives. Will include areas with same sedums as upper roof for comparison

  16. Completed upper roof on Sept 4 with sedum plants and canvas ballast installed Sedums are planted at low density. They will fill in greatly over time to create a true mat. Currently logging data which will be linked to classrooms and internet soon…

  17. Sensor stands
