You can now review the drafts for all LEED v4.1 rating systems.

LEED v4.1 is the newest update to the LEED rating systems. Focused on implementation, it is designed to be accessible, user-friendly and agile. Now, the drafts for all LEED v4.1 rating systems are available for you to download and review. Over the coming months, we’ll open registration for the LEED v4.1 betas that correspond to each draft. The timeline below outlines important dates to come, as well as what we have already done.

LEED v4.1 timeline

LEED v4.1 BD+C highlights

  • LEED v4.1 BD+C represents a series of upgrades that will update the referenced standards to encourage leadership, respond to market feedback and make our rating system more accessible than ever before.
  • To directly address the carbon impact of a building, for the first time, the energy metric is now both cost and greenhouse gas emissions.
  • In addition, to ensure leadership in building efficiency, the referenced standard for energy performance is ASHRAE 90.1-2016.
  • The Materials and Resources credits have been restructured to include options that acknowledge 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.
  • Other credits have adjusted thresholds based on market feedback, such as Rainwater Management requirements that now include a lowered minimum percentile for rainfall events and more guidance for zero-lot-line projects.
  • There is a new credit, Renewable Energy, that better addresses diverse methods of renewables procurement and evolving global renewables markets.
  • The compliance methodology in the Low-Emitting Materials credit is restructured to be more straightforward, while still promoting holistic consideration of the wide range of products installed in the building and how they impact indoor air quality.
  • The Daylight and Acoustic Performance credits are restructured to encourage more projects to consider daylight and acoustic performance during design and to give more flexibility to the designer to appropriately address important design considerations, including:

—excessive sunlight (for daylight), and
—sound transmission between spaces (for acoustics).

LEED v4.1 ID+C highlights

  • LEED v4.1 ID+C is a refinement that addresses market feedback for scenarios and processes specific to interior spaces, including challenges that projects face as they interact with their base building.
  • Many of the updates made to BD+C also apply to ID+C, including:

—the addition of a new greenhouse gas metric, and
—restructured materials credits that acknowledge 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.

  • Projects located in a LEED-certified building can now earn an additional point.
  • For naturally ventilated spaces, a new option is available for all ID+C projects located in an existing building, and the building does not have to be historic to qualify.
  • A new option in the Environmental Tobacco Smoke Control prerequisite acknowledges potential limitations with addressing smoking in areas outside of the interior project’s control. Smoking is still prohibited in the entire LEED project space.

LEED v4.1 O+M highlights

  • The rating system is simplified—the scorecard and requirements are streamlined, and new methodologies for tracking and rating performance are integrated directly into the rating system, providing a clear framework for achieving LEED certification—not just for entire buildings, but for spaces within buildings as well.
  • The rating system tracks performance in energy, water, waste, transportation, indoor air quality, toxin-free environment and occupant satisfaction.
  • To directly address the carbon impact of a building, for the first time, the energy metric is now both source energy use reduction and greenhouse gas emissions.
  • With LEED v4.1 O+M, an initial certification will be awarded to projects based on the implementation of sustainable operational strategies and performance score achievement in LEED Online for the areas below:

—Transportation: Administer at least one survey.
—Energy: Provide 12 consecutive months of total energy use.
—Water: Provide 12 consecutive months of total potable water use.
—Waste: Provide weight of waste generated and diverted over a 12-month period.
—Indoor Air Quality: Conduct at least one indoor air quality evaluation for total volatile organic compounds and interior carbon dioxide (CO2) level.
—Occupant Survey: Administer at least one occupant survey.

  • The resulting points for performance will translate into a LEED certification level.

LEED Residential highlights

  • LEED Residential features a single program, LEED for Residential v4.1, which includes Multifamily and a Core and Shell adaptation, as well as a Single Family Homes option.
  • The Core and Shell adaptation was developed to address a project type common in global markets.
  • Credits that have the highest value to consumers, such as energy and water savings; improved comfort, durability and health; and green materials have been prioritized.
  • The single-family rating system was streamlined to better focus on specific features of single-family construction.
  • The multifamily options incorporate the best aspects from our existing rating systems for Low-rise Homes, Midrise Homes and New Construction, merged into a single multifamily rating system.

LEED Cities and Communities highlights

  • The rating system has offerings for the plan and design of new cities and communities, as well as recognition for advances and the implementation of best practices in existing cities and communities.
  • Credits use a triple-bottom-line approach with scalable metrics that work for neighborhood developments, sustainable districts and mega-urban projects, all the way through the city, county and regional levels.
  • It provides verification of strategies and current levels of performance at both the planning and mature build-out/operational phases of all cities and communities’ evolution.
  • There is a greater focus on improved social equity, quality of life and standard of living.
  • The rating system includes flexible pathways to measure and advance local progress, including performance standards and proven strategies and best practices for improvement.
  • The expanded rating system for existing cities incorporates the high-performance metrics from the LEED for Cities pilot, standards from the STAR Community rating system and elements of key GBCI green energy and infrastructure rating systems like PEER and SITES.

Get started

The LEED v4.1 O+M beta is available now for all projects. Before we open registration for the remaining LEED v4.1 betas, we are giving teams the opportunity to preview the drafts and ask questions.
