The applicant needs to pay registration and certification fee to GBCI according to the predetermined fee structure, but no fee is required to pay to GBJ. If an applicant needs someone to help the process, it costs additional money to hire a consultant firm but GBJ doesn’t know about its market rate since it doesn’t have a direct access to LEED consulting market itself.
