LEED v4.1

Start a project

Who knew “.1” could deliver so much

In a world that is constantly evolving, one of the hallmarks of LEED is “continuous improvement.” With each new version, LEED raises the bar on the green building industry. From improving energy performance to emphasizing human health and integrative building design, LEED is encouraging project teams to operate beyond the status quo.

Enter LEED v4.1: LEED v4.1 will be our most inclusive and transparent platform to date. That’s because our most important requirement for adoption will come from our most valuable resource of all—you!

LEED v4.1 is bigger, stronger, bolder

  • Bigger: LEED v4.1 is for all – it is more inclusive with updated referenced standards and allows projects to earn LEED points through building performance monitoring.
  • Stronger: LEED v4.1 continues to drive performance, fully integrating performance outcomes supported by new methodologies and a simple data-driven path so that you can measure performance on an ongoing basis.
  • Bolder: Lessons learned from those in the market using LEED v4 and over the last twenty years have led us to take a deeper look at existing buildings, residential projects and cities to develop unique solutions that address unique markets.

LEED v4.1 Cities and Communities


LEED v4.1 BD+C

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.

  • 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
    • And a new Renewable Energy credit better that 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 O+M

The first step in launching LEED v4.1 included a version of the LEED rating system for existing buildings.

  • 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 ID+C

LEED v4.1 for Interior Design and Construction includes many of the updates made in LEED v4.1 BD+C as well as several that focus on the realities of interior spaces.

  • A new option within the Environmental Tobacco Smoke Control prerequisite that 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
  • Acknowledgment for projects located within a LEED-certified building
  • Lower entry points for both the Daylight and Acoustic Performance credits to encourage more projects to consider daylight and acoustic performance during design
  • Greater focus on improving indoor air quality through more approachable air testing options and use of the latest standards for ventilation
  • Learn more

LEED v4.1 Residential

LEED v4.1 presents a new approach to residential projects, that pulls the most relevant language from the BD+C and all residential focused rating systems and merges it with the priorities of the residential market.

  • One single program that consolidates all residential rating systems and guidance into three categories: Single Family Homes, Multifamily Core and Shell and Multifamily
  • Credits that have the highest value to consumers, such as energy and water savings; improved comfort, durability and health; and green materials are prioritized
  • Options added to existing credits lower both hard and soft costs to achieve certification
  • Multiple approaches for credit compliance are available as appropriate
  • Learn more

LEED v4.1 Cities and Communities

A new way forward for resilient, green, inclusive and smart cities, LEED for Cities and LEED for Communities provides 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.

  • 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 scaleable 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
  • Learn more

LEED recertification

LEED recertification is an important step in protecting your building asset. Recertification helps you maintain and improve your building, while keeping your sustainability investment in place. Recertification is available to all occupied and in-use projects that have previously achieved certification under LEED — including BD+C and ID+C, regardless of their initial rating system or version.

This new guidance presents a simple and data-driven pathway, reassuring projects that they are meeting ever-changing goals and staying on the cutting edge.

Step 1: Review the Recertification Guide, which details the requirements and process.
Step 2: Contact us to activate your project’s recertification.

Once you’ve successfully competed recertification, your project will earn LEED for Operations and Maintenance (LEED O+M) certification under the newest available version of the rating system. Currently that is LEED v4.1.
