Image 1.) A notice was written by lab workers. They want exhaust to be available to them when they are working in their hoods.

The Department of Environmental Health and Safety is Responsible for the annual re-certification of chemical fume hoods.

422 fume hoods in Chevron Science Center and Eberly Hall.

A 50% halfway open fume hood is 10 – 12″ (28 cm.) vertically.

1 year of all unused hood sashes open 50% would cost the University just over $250,000 in wasted energy.  e left open approximately 50% for one full year?”

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.

Exhaust:

Chevron labs and fume hoods require 8 Exhaust fans.

The 8 Fans that produce a combined 320000 cubic feet per minute of exhaust air = 4,200 household bathroom exhaust fans.
