Okay, so has anyone had time to scrutinize the just-released ASHRAE 62.2-2013 standard? How different is it from Addendum r?
I see it has finer increments in the Ventilation Air Requirements table 4.1. That's good.
Be sure to get the Errata sheet.
Qinf = may be no greater than 2/3 * Qtot. I read that as meaning even leaky houses may need mechanical ventilation.
Anyone have a -2013 spreadsheet…
