LEED v5 Implementation Timeline and Requirements

When Will LEED v5 Be Implemented?

LEED v5, the latest version of the Leadership in Energy and Environmental Design (LEED) rating system, is scheduled for implementation in early 2024. This update aims to further integrate decarbonization, improve quality of life, and enhance ecological conservation and restoration efforts within the built environment.

Key Features of LEED v5

LEED v5 builds upon the foundational goals of previous versions but introduces several key enhancements:

• Decarbonization: LEED v5 focuses heavily on reducing carbon emissions through advanced energy efficiency measures and the promotion of renewable energy sources. Projects aiming for LEED v5 Platinum must achieve industry-best practices for energy efficiency, eliminate on-site combustion except for emergencies, and utilize 100% renewable energy.
• Quality of Life: Enhancements include strategies to reduce air leakage and incentivize energy storage, leading to more resilient and reliable buildings that contribute positively to community well-being.
• Ecological Conservation and Restoration: Credits and prerequisites are designed to support biodiversity and ecosystem function, ensuring that projects not only minimize harm but also actively restore natural habitats.

Practical Guidance from Real Project Experience

From our experience at ISG, transitioning to LEED v5 requires a thorough understanding of the new criteria and a proactive approach to project planning. Here are some practical tips:

• Energy Modeling: Ensure your project's energy model is comprehensive and includes all energy types used within the project. This is crucial for compliance with the Estimated Energy Use and Operational Carbon Projection prerequisite (EAp1).
• Renewable Energy Integration: Explore opportunities for integrating renewable energy sources like solar panels or wind turbines to meet the stringent energy efficiency standards required for higher LEED ratings.
• Electrification: Transition to electrified operations to reduce reliance on fossil fuels and align with the decarbonization goals of LEED v5.

Specific Requirements and Credit Points

LEED v5 introduces several new credits and prerequisites that project teams must consider:

Credit/Prerequisite	Description	Points
EAp1: Estimated Energy Use and Operational Carbon Projection	Requires providing data on the project and annual energy use to visualize the impact of design decisions on operational carbon emissions.	N/A
EAc2: Enhanced Energy Efficiency	Offers an updated prescriptive option for achieving points through advanced energy efficiency measures.	Varies
EAc4: Enhanced Commissioning	Involves rigorous commissioning processes to ensure systems operate as intended, contributing to energy savings and performance.	Varies
EAc5: Grid-Interactive	Promotes energy storage and grid interaction to enhance building resilience and reliability.	Varies
