Review the full suite of LEED v4.1 rating systems to determine which is right for your project.

The full suite of LEED v4.1 rating systems is now open for registration. How do you know what to choose? Use the list below to point you in the right direction.

Building Design and Construction (BD+C)

This rating system is for buildings that are new construction or major renovations. At least 60% of the project’s gross floor area must be complete by the time of certification (except for LEED BD+C: Core and Shell). You must include the entire building’s gross floor area in the project.

  • New Construction and Major Renovation. New construction or major renovation of buildings that do not primarily serve residential, K–12 educational, retail, data centers, warehouses and distribution centers, hospitality or health care uses.
  • Core and Shell Development. Buildings that are new construction or major renovation for the exterior shell and core mechanical, electrical, and plumbing units, but not a complete interior fit-out. LEED BD+C: Core and Shell is the appropriate rating system to use if more than 40% of the gross floor area is incomplete at the time of certification.
  • Schools. Buildings made up of core and ancillary learning spaces on K–12 school grounds. LEED BD+C: Schools may be used for higher education and nonacademic buildings on school campuses.
  • Retail. Buildings used to conduct the retail sale of consumer product goods. Includes both direct customer service areas (showroom) and preparation or storage areas that support customer service.
  • Data Centers. Buildings specifically designed and equipped to meet the needs of high-density computing equipment such as server racks, used for data storage and processing. LEED BD+C: Data Centers only addresses whole-building data centers (greater than 60%).
  • Warehouses and Distribution Centers. Buildings used to store goods, manufactured products, merchandise, raw materials or personal belongings, such as self-storage.
  • Hospitality. Buildings dedicated to hotels, motels, inns or other businesses within the service industry that provide transitional or short-term lodging, with or without food.
  • Healthcare. Hospitals that operate 24 hours a day, seven days a week and provide inpatient medical treatment, including acute and long-term care.

Interior Design and Construction (ID+C)

This rating system is for interior spaces that are a complete interior fit-out. In addition, at least 60% of the project’s gross floor area must be complete by the time of certification.

  • Commercial interiors. Interior spaces dedicated to functions other than retail or hospitality.
  • Retail. Interior spaces used to conduct the retail sale of consumer product goods. Includes both direct customer service areas (showroom) and preparation or storage areas that support customer service.
  • Hospitality. Interior spaces dedicated to hotels, motels, inns or other businesses within the service industry that provide transitional or short-term lodging, with or without food.

Residential BD+C

Part of the BD+C rating system, Residential BD+C addresses residential buildings that are new construction or major renovation. At least 60% of the project’s gross floor area must be complete by the time of certification (except for LEED Residential BD+C: Multifamily Core and Shell Homes). Must include the entire building’s gross floor area in the project.

  • Single Family Homes. New single-family homes that are attached or detached, and multifamily buildings with up to four units.
  • Multifamily Homes. Applicable to any predominantly multifamily building with two or more units and any number of stories.
  • Multifamily Homes Core and Shell. Multifamily buildings that are new construction or major renovation for the exterior shell and core mechanical, electrical and plumbing units, but not a complete interior fit-out. It is the appropriate rating system to use if more than 40% of the gross floor area is incomplete at the time of certification.

More about LEED v4.1 residential:

  • LEED v4.1 Residential BD+C Multifamily Homes and Multifamily Homes Core and Shell are now available for registration in LEED Online for all countries except the United States and Canada. Projects in the United States and Canada can continue to use the LEED v4 rating systems available to residential projects and substitute credits from LEED v4.1 Residential.
  • With the release of the new multifamily options in LEED v4.1, Residential BD+C becomes the required rating system for all single family and multifamily projects. Residential projects using LEED v4.1 may not use LEED BD+C.

Cities and Communities

Cities are political jurisdictions or places defined by their municipal public sector governance (e.g., mayors or town managers) except in regions (especially Asia) where the term "city" is culturally understood as encompassing some places with private sector governance. 

Communities are defined as every urbanized location that is not a "city," including sub-city locations (such as districts), and meta-city regions (such as counties).  In addition, privately developed or owned urban areas (for example, Songdo District or Rockefeller Center) generally fit within the definition of "Community," except where they are self-identified (per definition of "city" above) as cities.

There are two options available for both cities and communities:

  • Plan and Design. New cities and communities that are in the planning/designing stage.
  • Existing.Cities and communities that are more than 75% built out.

Building Operations and Maintenance (O+M)

This rating system is for buildings that are fully operational and occupied for at least one year. The project may be undergoing improvement work or little to no construction. Must include the entire building’s gross floor area in the project.

  • Existing Buildings. Existing whole buildings.
  • Existing Interiors. Existing interior spaces that are contained within a portion of an existing building. Interior spaces may serve commercial, retail or hospitality purposes.
