Final answer:
The LEED rating systems are made up of a combination of credit categories, each with its own prerequisites and credits. The USGBC developed these systems to provide a comprehensive framework for sustainable building practices.
Step-by-step explanation:
The LEED rating systems, developed by the U.S. Green Building Council (USGBC), are made up of a combination of credit categories. These categories include Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, Indoor Environmental Quality, and Innovation in Design. Each category consists of specific prerequisites and credits that a building project can achieve.
For example, under the Sustainable Sites category, credits can be earned for things like selecting a site that reduces heat island effect or providing access to public transportation. Each credit has a specific point value, and projects can earn different levels of certification based on the total points achieved.
The LEED rating systems are not made up of interpretations, 3rd party standards, or impact categories. While the LEED rating systems are influenced by various standards and regulations, they are primarily developed by the USGBC to provide a comprehensive framework for sustainable building practices.
