BREEAM Projects Online

BREEAM Projects online can be used by clients and assessors for building and managing your portfolio of assessed projects under the Communities, New Construction, HQM, Infrastructure and Refurbishment schemes.

BREEAM Assessors can log-in and manage their registered assessments and seamlessly submit reports for certification decisions. If you’re not an assessor you can register for a free account, which gives you access to pre-assessment tools so you can get an early indication how your project might perform when assessed against BREEAM standards.

It provides assessment scenario and issue-specific principles and guidance for the application of scheme criteria.
