Final answer:
The USGBC has developed the LEED system to evaluate and certify sustainable buildings based on a variety of environmental and energy-efficient criteria. LEED is a globally recognized symbol of excellence in green building.
Step-by-step explanation:
The USGBC (U.S. Green Building Council) has established metrics and rating systems known as LEED (Leadership in Energy and Environmental Design) to measure building performance. LEED provides a framework for healthy, highly efficient, and cost-saving green buildings. Through its comprehensive system, buildings are evaluated across several categories including energy usage, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources. Buildings that meet certain criteria receive LEED certification, which is internationally recognized as a symbol of sustainability achievement and leadership.
Another metric USGBC has adopted is the Energy Star certification, which assesses a building's energy efficiency. Buildings that meet Energy Star's performance standards are recognized for their energy savings and environmental benefits.
Additionally, USGBC has implemented the Building Performance Partnership, a program that focuses on measuring and improving the actual performance of buildings. Through this program, building owners can track their energy and water consumption, compare their performance against similar buildings, and identify areas for improvement.
