Use of the GBE™ Designation
A Certified Green Building Engineer (GBE™) may use the designation with his/her name on organization letterhead or business cards. Certification is for individuals only. The GBE™ designation may not be used to imply that an organization is certified.

GBE certification is only valid withthe maintenance of current status of Certified Energy Manager (CEM) and a U.S.-issued Professional Engineers (PE) license. Once you have attained GBE status, renewal of your GBE certification will take place at the same time your CEM is renewed.


When CEM® certification is renewed every three years at the regular CEM® renewal rate of $300.00 and documentation is provided confirming P.E. licence remains current, the GBE™ certification will also be renewed for a discounted fee of $125.00 (except for grandfather clause participants, who will not pay GBE renewal fees). No refunds allowed.
