ASHRAE certification designations should be listed after certificant names in ASHRAE print and electronic media pieces which also cite the P.E., P.Eng. and Ph.D. designations.

Please find the following related guidance:

  • If a certficant also holds the P.E., P. Eng. or Ph.D. designation, then the ASHRAE certification designation should follow. 

Example:  Jane Doe, P.E., BEMP

  • Multiple certification designations should be ordered alphabetically.         

Example:  John Doe, BEAP, BEMP

  • If a certificant has numerous ASHRAE certifications and space is limited, then cite the certification(s) most relevant to the media piece in question 

Example: “Energy Modeling in the 22nd Century” John Doe, BEMP

Degrees, Member Grades, Designations and Certifications in Bylines

  • Degrees, member grades, designations and certifications can be used in author and instructor bylines.

Example: “John Smith is a certified ASHRAE Building Energy Modeling Professional (BEMP).”

  • ASHRAE lists Ph.D., D.Sc., or other equivalent doctoral-level degree (some Europeans use Dr.lng.).
  • ASHRAE does not list degrees at the bachelor or master's degree level in printed materials.



BACnet referenced with the ASHRAE logo should always carry ® mark. BACnet referenced alone should only carry ™ mark on first use within a written document.

  • In trademark notices, the word “registered” should not be included.

Example: BACnetTM is a trademark of American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
