Green Globes for Existing Buildings


Improving the sustainability of existing buildings is critical to forging a better built environment. Green Globes for Existing Buildings 2021 is a science-based, user-friendly benchmarking and certification program evaluating the environmental sustainability, health and wellness, and resilience of an individual building or entire portfolio.

The user-friendly online questionnaire and integrated Green Globes assessment process enable project teams to:

  • Establish a baseline and guide for improvement
  • Assess opportunities for energy savings, reduce environmental impacts, and lower maintenance costs
  • Establish baselines by importing energy, water, emissions, and waste data to measure progress and compare performance
  • Compare Green Globes and utility consumption performance among portfolio properties
  • Clone questionnaires to use for subsequent certifications within a portfolio for efficiency

Developed using applicable content from ANSI/GBI 01-2019 Green Globes Assessment Protocol for Commercial Buildings (Green Globes NC 2019), Green Globes EB 2021 provides a comprehensive roadmap for practitioners who are implementing sustainability programs or who wish to expand existing sustainability programs. Criteria evaluated within Green Globes EB 2021 support environmental, social, and governance (ESG) goals and corporate sustainability reporting (CSR).


“The fact that Green Globes, even with its enhanced rigor, can be used for almost any property type should be important for the overall real estate market.”

– Brenna Walraven, CEO, Corporate Sustainability Strategies
