Most projects rely on accredited professionals:
BREEAM Assessors and APs (Accredited Professionals) for BREEAM
LEED Green Associates and LEED APs for LEED
These specialists guide the design team, coordinate evidence, advise on achievable credits, and make sure decisions align with certification goals. Environmental consultants, energy modellers and IAQ specialists often support the process too, depending on the credit requirements.
Having an expert involved early typically prevents issues later and makes the whole certification journey more efficient.
