Ace the LEED Green Associate Exam 2025 – Go Green, Go Great!

The correct answer is that a project must recertify every 5 years under the LEED for Operations and Maintenance (O+M) Existing Buildings rating system. This recertification frequency allows projects to demonstrate ongoing compliance with LEED standards and showcase improvements in sustainable operations over time.

This timeline is significant as it ensures that buildings maintain their performance and sustainability goals, adapting to any changes in regulations or standards while promoting continued excellence in building operations. Frequent recertification helps reinforce the commitment to sustainability, but extending the period to every 5 years balances the effort required with practical considerations of building management.

In the context of LEED O+M, this recertification process encourages long-term sustainable practices rather than placing an excessive burden on building managers or operators. The other frequencies mentioned do not align with LEED guidelines and would not effectively incentivize the maintenance of sustainable practices over the lifespan of the building.
