In every building, a ventilation system
It runs
all year round.
Existing air handling unit

Its motor is dated
It can only do
two things.
SlowlyFast
And nothing in between.

What changes,
what stays put.
What stays in place
The existing wiring
The distribution board
The building’s controls
What changes
The motor
