A Second Look at Green Buildings: The Rise of Certifications around the World

Share this Post:
Green building is on the rise around the world, through a mix of voluntary certification and mandatory requirements. Once an area dominated by the prevalence of new construction, the green building landscape is looking increasingly familiar: in existing buildings.

In 2008 the United States Green Building Council redefined its existing buildings approach to focus on whole building energy performance.  That year, a repositioned standard, LEED for Existing Buildings: Operations and Maintenance (EBOM), was released - requiring whole-building energy metering and one year of energy performance reporting. Since then, the existing buildings category of LEED-certified buildings has experienced an explosion. The overall LEED rating system has expanded its international presence at an unprecedented level – approximately 40 percent of LEED-registered projects and half of LEED-EBOM projects are located outside of the United States.  Read our article and learn about who are the drivers of the global greening of existing buildings, in Europe and worldwide.
