LEED v4.1 AGÕæÈË°Ù¼ÒÀÖ¹ÙÍøÈë¿Ú Design and Construction

The LEED v4.1 evolution for the design and construction of full buildings focuses on accessibility, the most current standards and real-world project experiences. 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, Kâ€�12 educational, retail, data centers, warehouses and distribution centers, hospitality or health care uses.
• Core and Shell Development. AGÕæÈË°Ù¼ÒÀÖ¹ÙÍøÈë¿Ús 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. AGÕæÈË°Ù¼ÒÀÖ¹ÙÍøÈë¿Ús made up of core and ancillary learning spaces on Kâ€�12 school grounds. LEED BD+C: Schools may be used for higher education and non-academic buildings on school campuses.
• Retail. AGÕæÈË°Ù¼ÒÀÖ¹ÙÍøÈë¿Ús 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. AGÕæÈË°Ù¼ÒÀÖ¹ÙÍøÈë¿Ús 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 address whole-building data centers (greater than 60%).
• Warehouses and Distribution Centers. AGÕæÈË°Ù¼ÒÀÖ¹ÙÍøÈë¿Ús used to store goods, manufactured products, merchandise, raw materials or personal belongings, such as self-storage.
• Hospitality. AGÕæÈË°Ù¼ÒÀÖ¹ÙÍøÈë¿Ús 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.

Updates

• Energy metrics include both cost and greenhouse gas emissions (a first for LEED)
• Upgrade to ASHRAE 90.1-2016
• Applicable and achievable credit requirements throughout the rating system
  • For example, updated Rainwater Management requirements with a lower minimum percentile storm events and added guidance for zero-lot-line projects
  • A new Renewable Energy credit addresses diverse methods of renewables procurement and evolving global renewables markets
  • Restructured Materials and Resources credits that include options acknowledging efforts at varying levels, bridging the gap from where the market is currently to the goals identified in LEED v4 and carried into LEED v4.1

LEED v4.1 Operations and Maintenance

The first step in launching LEED v4.1 included a version of the LEED rating system for existing buildings. This rating system is for buildings that have been fully operational and occupied for at least one year. The project may be undergoing improvement work or little to no construction. The project must include the entire building’s gross floor area.

• Existing AGÕæÈË°Ù¼ÒÀÖ¹ÙÍøÈë¿Ús. 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.

Updates

• A shift from documents for documentation to data for documentation by tracking performance in energy, water, waste, transportation, indoor air quality, toxin-free environment and occupant satisfaction
• Get certified and stay certified with data-driven recertification guidance that aligns with certification requirements
• LEED points are based on performance (score)
• For the first time applies to buildings and interior spaces

LEED v4.1 Cities and Communities

LEED for Cities and LEED for Communities provide cities and communities with a globally consistent way to measure and communicate performance. LEED v4.1 expands the solutions for LEED for Cities and LEED for Communities to include two new project types, those in the planning and design phase and existing cities. .

• 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).â€� 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 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.

Updates

• Expanded rating system now includes standards from the STAR Community Rating System and elements of key GBCI green energy and infrastructure rating systems like PEER and SITES
• Triple bottom line approach with scalable metrics that work at the city, county and regional scale
• Flexible pathways to measure and advance local progress, including performance standards and proven strategies and best practices for improvement
• Greater focus on improved social equity, quality of life and standard of living
