Green Globes for Existing Buildings (EB)

Sensible Solutions to Reach Your Building’s Potential

Improving the sustainability of existing buildings is critical to forging a better built environment. At the Green Building Initiative® (GBI), we realize it needs to be a manageable process that combines professional knowledge with proven science and offers education along the way. That’s why we created the Green Globes® for Existing Buildings (EB) tool as a user-friendly, web-based application with options for attaining your building’s highest potential. If you have a multifamily project, check out the  Green Globes Multifamily EB tool too! 

Using the EB assessment process enables building teams to focus on sustainability, and gives them choices when considering capital improvements or implementing of best practices.


  • Comprehensive environmental assessment road map
  • Benchmark your facility and rate the benefits of various building attributes
  • Personalized guidance for green construction and building operations’ best practices
  • Online software tools that speed and simplify the assessment process
  • Qualified assessors with green building expertise verifying project achievements on site

Standards by which to benchmark your facility and rate the benefits of various building attributes

After your team completes a survey, Green Globes generates a report to help you evaluate green building best practices opportunities to save energy, reduce environmental impacts, integrate corporate goals and practices, and lower maintenance. Once you choose features and practices that make sense and you're ready for external evaluation, an expert third-party assessor visits your facility, provides guidance, recommends ways to streamline operations, and offers quality assurance throughout the process. In addition, the Green Globes Assessor can offer suggestions for future improvements as capital funds become available. This interactive approach provides the quickest and most affordable way to advance the sustainability of your existing building.

Green Globes EB covers six different environmental assessment areas, with each area using weighted criteria and an assigned number of points that are used to quantify overall building performance and use of best practices.

The building must attain a minimum overall score of 35% to be certified.
