Stormwater study in Nest at UBC Oct. 6th 2020
Sections show the stormwater collection system in Nest.
When I walked in the building, I found out the stormwater pipeline runs on the ceiling of the main floor. Also, the direction is from upstairs to two directions, West and East. One pipe is connected with downstairs from a pizza restaurant, another connects with the ceiling of RBC and directs to the exterior.
West exit with open lawn area 
East exit with stores
In class study of drainage system
The black points show the pipe areas which connect with the gutters.
