Thanks Jim,

So your understanding is that a mixing box still exists, but the control that varies outdoor air rate doesn't exist. It is in effect a fixed outdoor air rate.

Many thanks

Chris,
More warm weather  = less available cooling from outdoor air = less justification for spending money to install economizer controls.
p.s., You must provide minimum outdoor air for ventilation, but need not also cool with outdoor air

Is it just me, or is does it seem terrifically wasteful that a climate 1 building doesn't require an economiser? Or am I missing something?
