ASHRAE 62.2 Morsels – 2

I am often asked about the more difficult or contentious details of the 62.2 Standard. These questions range from replacing kitchen wall fans and the pros and cons of double-duty fans, to tuning in the dwelling-unit ventilation at the final inspection. This is the second  of two articles including a collection of these questions from users of the 62.2 Standard and the RED Calc 62.2 tools, along with my best answers.

ASHRAE 62.2 Morsels – 1

As a fifteen-year member of the ASHRAE 62.2 committee, I am often asked about the more difficult or contentious details of the 62.2 standard. These questions range from how to measure dwelling height, should the basement be included in the floor area, or how to determine the airflow rate of balanced ventilation. This is the first of two articles including a collection of these questions from users of the 62.2 Standard and the RED Calc 62.2 tools, along with my best answers.

Best Practices for Residential Ventilation

Ventilation installation practices are usually based on ASHRAE 62.2 in the U.S., the only question being which version of this standard is used by the relevant program.

Major Study Shows ASHRAE 62.2 Ventilation Works!

A significant research report published in April of this year by the National Center for Healthy Housing (NCHH) found that subsidized multifamily housing with ASHRAE 62.2-compliant ventilation had better indoor air quality than housing without 62.2-compliant ventilation. This important research states: “Levels of four of the five indoor contaminants improved substantially with [continuous] mechanical ventilation."

It is difficult to assign a cost to a bad night’s rest, but I think most of us agree that it’s a cost we would rather avoid.
