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.
