About GBI

What We Do

We deliver education, credentialing, standards, assessments, and certifications developed by an inclusive and collaborative global network. GBI makes aspirational goals achievable through user-friendly tools built upon comprehensive standards and supported by dedicated staff and expert assessors. As a nonprofit community, we are educators and coaches first, supporting performance improvement of all buildings.

How We Do It

GBI promotes the use of our standards, assessments, and tools that act as roadmaps, helping teams make impactful decisions that support our vision. Our initiatives are designed to meet the evolving needs of organizations seeking meaningful, measurable performance improvements throughout their buildings and sustainability strategies.

GBI’s Third-Party Assessments

Our programs are designed to align with both international and local regulatory frameworks, while also addressing owner, investor, and stakeholder expectations for cost optimization, social responsibility, and transparency in reporting.

We offer organizations a flexible and forward-thinking ecosystem that supports measurable progress for individual assets, full portfolios, and enterprise-wide strategies.

We are passionate about third-party certification as it lowers risk for owners while ensuring that buildings and the teams who build and operate them are better able to achieve desired performance outcomes. There is education embedded in each program means every person, team, and building we touch has a positive downstream impact on our global built environment and society.

Green Globes® is our science-based, whole building certification that evaluates the sustainability, health & wellness, and resilience of all commercial real estate.
