Education & Certification

Renewal Recertification Requirements

Each Certificant is required to renew his/her certification every three years. The renewal process includes submittal of a renewal fee ($125 for members, $195 for non‐members) and evidence of earning 45 ASHRAE Continuing Education (ACE) units during each three‐year renewal period.* The three‐year renewal period starts on December 31 of the year in which the Certificant earns the certification. For example, a Certificant who earned the certification anytime in 2008 will have a renewal deadline of December 31, 2011. Individuals who fail to submit renewal fees and evidence of the required ACEs by the December 31 deadline will be considered as 'non‐renewing,' notified accordingly, and advised to cease using the specific certification designation after their names. The names of non‐renewing Certificants will be removed from the list of Certificants on ASHRAE’s website. To be reinstated, non-renewing Certificants must submit the renewal fee, a reinstatement fee ($60), and evidence of the required ACEs by December 31 of the year following their active status. After that date, non‐renewing Certificants must follow the same process as that for the initial application. Extenuating circumstances will be reviewed on a case-by-case basis by the Committee.

*Certificants are not required to submit a report of Professional Development activities as part of certification renewal. A percentage of Certificants are randomly chosen for audit each year. If audited, a report of continuing professional development with documentation must be submitted for review.

Activities that qualify for ASHRAE’s Continuing Education units might also qualify for continuing education credits (e.g., PDHs, CEUs, or LUs) from other credentialing bodies or organizations. The individual is responsible for contacting the relevant governing body to determine whether an activity qualifies for that body’s continuing education credit.
