[Greenbuilding] fresh air in a library

[Ted Inoue]

Run a blower door test and prove that the natural ventilation rate exceeds
the ASHRAE specified levels. If called for, damper the fresh air intake,
measure again to ensure that there's still enough.

Make sure you talk to the code official to determine what level of
ventilation is required.
