Green Globes Assessor

1. Review eligibility requirements: Confirm you meet GBI's professional experience requirements — typically a background in architecture, engineering, construction management, or sustainability consulting is expected before applying.

1. Register with GBI: Create an account on the GBI website (thegbi.org) and submit your application for the Green Globes Assessor credential, including any required documentation of professional experience.

1. Complete required training: Enroll in and complete GBI's official Green Globes Assessor training course, which covers the Green Globes rating system, assessment methodology, energy and water criteria, and the third-party verification process. This is typically available online and self-paced.

1. Study the Green Globes rating system: Supplement your training by reviewing the Green Globes technical reference manuals, ANSI/GBI standards, and sample assessment questionnaires available through the GBI portal.

1. Schedule and sit for the exam: Register for the proctored Green Globes Assessor examination through GBI. The exam is delivered online with proctoring and covers all major domains of the Green Globes system.

1. Pass the exam and receive your credential: Upon passing, GBI will issue your Green Globes Assessor credential, authorizing you to conduct third-party assessments for building projects seeking Green Globes certification.

1. Maintain your credential: Complete continuing education requirements and pay the renewal fee every two years to keep your Assessor credential active and in good standing with GBI.

The Green Globes Assessor exam evaluates a candidate's knowledge of the Green Globes rating system and their ability to apply it in real-world building assessment scenarios. The exam covers the full range of Green Globes assessment categories used to evaluate commercial buildings, including: Energy (typically the highest-weighted category, covering energy modeling, efficiency measures, and ASHRAE compliance), Water (conservation strategies, fixture efficiency, and site water management), Indoor Environment (air quality, thermal comfort, lighting, and acoustics), Site (land use, ecology, transportation, and stormwater), Materials (product selection, waste reduction, and life-cycle considerations), Emissions (greenhouse gas, refrigerants, and pollution prevention), and Project/Environmental Management (commissioning, operations planning, and stakeholder engagement).

Candidates are also assessed on their understanding of the third-party assessor role — including how to conduct site visits, review documentation submitted by project teams, score questionnaire responses, and produce assessment reports. Knowledge of relevant standards such as ASHRAE 90.1, ASHRAE 62.1, and the ANSI/GBI 01 standard is expected.

The exam uses multiple-choice questions designed to test both conceptual understanding and applied judgment, requiring candidates to interpret project scenarios and determine appropriate Green Globes scores or recommendations.

Green Globes occupies a distinct niche in the U.S. green building certification market as one of only two federally recognized whole-building rating systems — the other being LEED. This federal recognition, established through the Energy Policy Act and reinforced by GSA and Department of Defense adoption, gives Green Globes a meaningful foothold in government and institutional construction that many competing programs lack. However, LEED remains the dominant credential in the broader market, with significantly more certified buildings, credentialed professionals, and employer demand globally.

Green Globes has found particular traction in commercial office, healthcare, and government facility sectors, where its web-based, questionnaire-driven approach is seen as more accessible and less documentation-intensive than LEED. The program has over 1,600 certified buildings in the U.S. and a growing presence in Canada, where it originated. The Green Globes Assessor credential is relatively niche compared to LEED AP, with a smaller but dedicated professional community. For professionals working primarily in U.S. federal or state government projects, or in markets where clients seek a LEED alternative, the GGA credential carries real practical value.

The broader green building credentials market is growing as ESG reporting requirements, building performance standards, and energy codes tighten. Green Globes benefits from this trend, particularly as building owners seek flexible, cost-effective paths to demonstrating sustainability performance. The ANSI/GBI standard underpinning Green Globes also lends it credibility with technically oriented clients. That said, international recognition remains limited compared to LEED or BREEAM, and professionals seeking global mobility should weigh this carefully.

Green Globes originated in Canada in the late 1990s as an online environmental assessment tool developed by BREEAM Canada (a derivative of the UK's BREEAM system) and later adapted by ECD Energy and Environment Canada. It was designed to provide a practical, web-based alternative to more documentation-heavy rating systems, with a particular focus on usability for smaller project teams and budget-conscious owners.

In 2004, the Green Building Initiative (GBI) — a nonprofit organization — licensed the Green Globes system for use in the United States and began adapting it to the U.S. market. GBI subsequently developed the ANSI/GBI 01 standard, which formalized the Green Globes criteria as an American National Standard, lending the program additional technical credibility. A key milestone came when the U.S. federal government recognized Green Globes as an approved green building rating system for federal facilities, placing it alongside LEED as one of only two federally sanctioned options. GBI has continued to update the rating system and expand its professional credentialing program, including the Green Globes Assessor (GGA) and Green Globes Professional (GGP) designations, to support the growing ecosystem of professionals working with the system.
