"Here is a more detailed article about the incident.  Rescuers measured 1,000 ppm in the bedroom! A picture of the concentric vent is shown and it looks like the intake is partially blocked with snow.   "

ASHRAE 62.2-2013 released

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 calculator yet?Will the $20…See More

"Paul Francisco's alternative method is just fine. He has simplified the math for the procedure. Even with Paul's simplification, a spreadsheet or calculation sheet is a good idea. Regarding ductwork, remember that the ASHRAE 62.2 Standard…"
