THESE THREE THINGS 885


I was lucky enough to go on a bts tour of the @calacademy today. I’ll be digesting all I learned for a while, but here are three kick ass things I learned about the living roof. 



1. The Academy does not have an active heating or cooling system. The roof is designed to collect sinking cool air by surrounding an open ventilation system in a valley between 7 hills. Visitors provide body heat to warm the building which is well insulated by denim within the walls. Warm air rises and is released through the roof via skylight pods that open to release the warm air.

2. A grid of volcanic rock on the roof absorbs and guides rain water through a grey water drainage system collection.

3. The living roof covers roughly 2 acres. That plus the immediate surrounding gardens of the Academy make up the largest native plant habitat in all of San Francisco.
