Green Roof (GR) Research

gritlab is evaluating the City of Toronto's Green Roof Construction Standard with respect to four performance criteria: 1) Stormwater Retention, 2) Evaporative Cooling,
3) Biodiversity, 4) Life Cycle Cost.

33 test beds compare four parameters: 1) Growing Media Type (FLL/organic), 2) Depth (4"/6"), 3) Vegetation (sedum/biodiverse), Irrigation (none/timer/moisture sensor).
