Issued by: Green Building Certification Institute (GBCI) / USGBC
The leading credential for optimizing the energy performance and sustainability of existing commercial buildings. Required by major property management firms and increasingly demanded by ESG-focused real estate owners.
LEED AP Operations + Maintenance (O+M) is a GBCI credential that certifies expertise in applying the LEED O+M rating system to existing commercial buildings. Unlike LEED BD+C (which focuses on construction of new buildings), O+M focuses on optimizing energy performance, water efficiency, occupant health, and sustainability of buildings already in operation.
The credential is well-suited for facility managers, property managers, energy managers, and sustainability consultants working with existing commercial building portfolios. LEED O+M uses a performance-based approach — buildings must demonstrate actual operational performance improvements, not just design intent.
Market context: Approximately 80% of the buildings that will exist in 2050 are already built today. This makes existing building performance optimization the largest commercial opportunity in the sustainability sector — and LEED AP O+M is the credential that signals expertise in exactly this space.
As ESG reporting requirements tighten — SEC climate disclosure rules, GRESB (Global Real Estate Sustainability Benchmark) benchmarking, and investor ESG questionnaires — commercial real estate owners need professionals who can optimize existing building performance and document improvements systematically.
LEED O+M certification of existing buildings requires a LEED AP O+M on the team. Corporate sustainability teams managing large building portfolios increasingly require this credential for in-house or contracted sustainability managers. The IRA's 179D Commercial Buildings Energy Efficiency Tax Deduction creates additional demand for O+M-knowledgeable professionals who understand what improvements qualify.
Major property management firms including JLL, CBRE, and Cushman & Wakefield specify LEED AP O+M for sustainability roles because their institutional and REIT clients are asking for measurable building performance improvements that can be reported to investors and regulators.
Commercial signal: LEED AP O+M tells property owners, asset managers, and investors that the professional understands how to measure, improve, and certify the operational sustainability performance of existing commercial buildings — the skill set that ESG reporting demands.

LEED AP O+M follows a 2-year renewal cycle. Credential holders must earn 30 continuing education (CE) hours per cycle, with at least 6 hours specifically related to O+M topics. GBCI accepts diverse approved providers including ASHRAE, AEE, BOMA (Building Owners and Managers Association), IFMA (International Facility Management Association), and USGBC education programs.
Given the evolving nature of ESG reporting requirements and building performance standards, active O+M credential holders benefit from staying current with ENERGY STAR updates, building benchmarking regulations (such as local benchmarking ordinances), and emerging LEED rating system updates.
LEED AP O+M is required or strongly preferred by the organizations that own and manage commercial real estate at scale:
Recognized by the GRESB assessment framework, which is used by over 900 institutional investors to benchmark real estate portfolios. Preferred by REITs and institutional building owners managing large portfolios of existing commercial buildings.
LEED AP O+M is administered by the Green Building Certification Institute (GBCI). Applications, exam scheduling, and renewals are managed through the GBCI portal.
