Air Supply:
Chevron Science Center has two air handling units,
Each supplies 140,000 cubic feet of air per minute each = air to cool 233 average single family homes in the summer.

Chevron labs and fume hoods require 8 Exhaust fans.
The 8 Fans producing a combined 320000 cubic feet per minute of exhaust air = 4,200 household bathroom exhaust fans.
