This standard has undergone quite a few updates and revisions. In fact, the 1999 version of the standard has been under continuous maintenance for the last three years. The ASHRAE committee in charge of revising the standard has been looking for ways to make the guidelines clearer and more precise, while at the same time trying to adopt criteria that would make indoor environments healthier and more comfortable.
According to Andrew Persily, Ph.D., chairman of the Standard 62 committee, several addenda have been approved for publication in the standard. If all goes as planned, ASHRAE may be able to unveil its revised version of Standard 62 at its Winter Meeting in Atlantic City, NJ, Jan. 14-16, 2002.
