LEED v5, the next version of the rating system from USGBC, represents a significant advancement in green building standards, pushing beyond local code requirements to address critical sustainability challenges.

With several new, merged and expanded credits, LEED v5 will transform the certification landscape, driving change across multiple rating systems within the LEED family. While this article doesn't delve into specific differences between LEED rating systems, it is important to note that the existing building rating system (LEED for Operations and Maintenance) stands apart due to its unique focus on operational performance.

As sustainability consultants, we at Stok are particularly stoked about these five major categories and the new credits associated with them:

Platinum: Building Design and Construction: New Construction—various credits are now required to achieve LEED Platinum.
Carbon: Carbon Assessment (Prerequisite)
Transportation: Transportation Demand Management (TDM) (Credit), Active Travel Facilities (C), Electric Vehicles (C)
Passive design: Reduce Peak Thermal Loads (C), Water Reuse (C)
Waste: Planning for Zero Waste Operations (P)

The new Platinum standard

USGBC has raised the bar in terms of certification levels by adding specific required credits to advance decarbonization goals to achieve Platinum certification. Achieving LEED Gold will be challenging, and Platinum will be an even more prestigious goal! LEED v5 guides the industry toward decarbonization through these Platinum-required credits:

Energy and Atmosphere (EA) credit Electrification
EA credit Enhanced Energy Efficiency
EA credit Renewable Energy
Materials and Resources (MR) credit Reduce Embodied Carbon

All the above-required credits are linked to decarbonization strategies, reflecting comprehensive decarbonization strategy as fundamental to realizing high performance. The Electrification credit future-proofs projects in anticipation of a clean grid and gets combustion out of buildings. Enhanced Energy Efficiency optimizes system design to support net zero energy and carbon goals. The Renewable Energy credit incentivizes addressing both on-site and off-site energy needs with clean energy solutions. Finally, Reduce Embodied Carbon focuses on minimizing embodied carbon through the selection of materials with low global warming potential for structure, enclosure and hardscaping through a whole building life cycle assessment.

Carbon reduction moves to the forefront

The Carbon Assessment prerequisite shines a spotlight on the importance of operational carbon and decarbonization by requiring the design team to develop a 25-year Operational Carbon Projection and Decarbonization Plan. Project teams will need to take a holistic look at emissions reduction, sparking additional analysis to determine how their projects are affecting the environment.

Rewarding holistic sustainable transportation solutions

LEED v5 has enhanced its approach to sustainable transportation, building on the Location and Transportation category from LEED v4. The new version introduces strategic mobility solutions, including transportation demand management, micromobility options and expanded electric vehicle charging requirements.

By focusing on comprehensive mobility solutions, LEED v5 aims to reduce transportation-related environmental impacts and lower Scope 3 emissions (indirect emissions from a company’s value chain, such as employee commuting). These updates reflect a growing recognition of the importance of mobility in buildings and communities, aligning with urban planning trends that promote multimodal transportation and reduced reliance on single-occupancy, fossil fuel–dependent vehicles.

Passive design rises

The Energy category in LEED v5 is crucial for advancing decarbonization in the built environment. A welcome addition is the Reduce Peak Thermal Loads credit, which aligns with Passive House Institute U.S. (PHIUS) standards. This credit includes compliance with the ASHRAE 90.1 Building Envelope Trade-off modeling path and the use of passive design tools, such as PHIUS's WUFI Passive Design Tool.

By focusing on reducing peak thermal loads, this credit promotes energy savings and enhances building performance. Its emphasis on passive design strategies and detailed envelope modeling, particularly regarding thermal bridging, encourages a closer look at an often overlooked element of building design.

A renewed effort to address water scarcity can be seen in the Water Reuse credit. Previously this strategy was buried within the Indoor Water Use Reduction credit; it now sits center stage as its own credit promoting the reuse of water in urinals, water closets and make-up water systems. Integrating water reuse systems reduces reliance on municipal water supply, easing pressure on local resources and ensuring greater water resilience through a closed-loop system. USGBC also highlights and rewards reductions in whole project water use by adding an option for a credit that was previously in the Innovation Category. It is now Option 1, Whole Project Water Use, under the Enhanced Water Efficiency credit.

Circular economy principles for zero waste operations

LEED v5 emphasizes zero waste through the new Planning for Zero Waste Operations prerequisite, which adapts the LEED v4 Storage and Collection of Recyclables prerequisite and demands a more proactive approach to waste management. This prerequisite challenges project teams to thoroughly plan and understand future waste streams, requiring due diligence on local waste laws, manufacturer take-back programs, recycling options, composting processes, and repair and reuse initiatives.

We're seeing growing momentum around waste reduction, with corporate clients increasingly pursuing impactful strategies like TRUE certification for zero waste. This shift reflects a strong commitment to minimizing landfill use and optimizing resource recovery both upstream and downstream. By formalizing these requirements, USGBC is promoting circular economy principles and driving the industry toward operations that are truly zero waste.

Are you stoked for v5?

LEED remains a cornerstone in the sustainable building industry, providing a comprehensive framework for environmentally responsible design and construction practices. The introduction of LEED v5 marks a significant evolution, emphasizing critical areas such as decarbonization, ecosystem conservation and equity. This latest version reinforces LEED's relevance by addressing the urgent need for climate action and social responsibility, while raising the bar for design, construction and operations within the built environment.
