LEED v5 Changes Summary

LEED Operations + Maintenance: Transition from v4 to v5

  • Overview of LEED v5

    • Focuses on low carbon features and sustainability.

    • Centers on three areas: decarbonization, quality of life, ecological conservation.

  • Credits and Prerequisites

    • Every credit/prerequisite ties into the three main areas.

    • New requirements for LEED Platinum include thresholds for:

    • Energy efficiency

    • Greenhouse gas emissions reduction

    • Future operational emissions plans

    • Introduction of the Integrative Process (IP) credit focusing on holistic sustainable assessments.

  • Client Resilience and Human Impact

    • New prerequisites added related to client resilience, human impact, social equity, and operational assessments.

  • Location and Transportation

    • Promotes sustainable mobility and reduces emissions through alternative transport.

    • Shifted from single-occupancy vehicles to active/shared transport modes.

    • New credits in this category include Sustainable Transportation Performance and Transportation Demand Management.

  • Sustainable Sites

    • Focus on managing relationships between buildings and the environment.

    • Strategies to mitigate temperatures, reduce wildlife impact, and enhance resilience.

    • Important requirements targeting light pollution and bird collisions have been set.

  • Water Efficiency

    • Emphasis on conserving water resources and enhancing resilience.

    • New prerequisites focus on water efficiency, with updated requirements for metering.

    • Introduction of metrics for whole building water use efficiency.

  • Energy and Atmosphere

    • Aims for net zero carbon operations through efficiency and renewable energy.

    • Prerequisites for energy monitoring and comprehensive refrigerant management updated.

    • New credits include monitoring greenhouse gas emissions and decarbonization approaches.

  • Materials and Resources

    • Focus on waste reduction and circular economy principles.

    • Emphasizes tracking waste streams to minimize landfill impact.

    • New Waste Reduction Performance credit introduced, promoting resource preservation and sustainability.

  • Indoor Environmental Quality

    • Strategies to enhance human health and minimize pollutants through air quality and comfort practices.

    • New prerequisites for verification of ventilation, and air filtration systems introduced.

    • Emphasis on occupant feedback and comfort improvement strategies.

  • Project Priority and Innovation

    • Focuses on regional sustainability practices and health priorities.

    • Innovation credit merged with project priorities to include regional priority points.

    • At least one LEED Accredited Professional is required on project teams.

In LEED v5, the new prerequisites and credits are systematically aligned with the three main impact areas to ensure a holistic approach to sustainability. Here is how they correspond:

  1. Decarbonization

    • Energy and Atmosphere: This category is the primary driver for carbon reduction, featuring prerequisites for energy monitoring and new credits for monitoring greenhouse gas (GHG) emissions. It aims for net-zero carbon operations through efficiency and renewable energy.

    • Location and Transportation: Redesigned to reduce emissions by incentivizing a shift from single-occupancy vehicles to active and shared transport modes.

    • LEED Platinum Requirements: New thresholds specifically target energy efficiency and GHG emissions reduction.

  2. Quality of Life

    • Indoor Environmental Quality: Focuses on human health through air filtration systems, ventilation verification, and strategies for occupant feedback and comfort.

    • Human Impact and Social Equity: New prerequisites under Client Resilience and Human Impact specifically address social equity and operational assessments to improve the experience of building occupants.

    • Innovation: Merged with project priorities to address regional health and sustainability priorities.

  3. Ecological Restoration

    • Sustainable Sites: Directly addresses the relationship between the building and its environment by mitigating temperatures and protecting wildlife through light pollution and bird collision requirements.

    • Water Efficiency: Emphasizes the conservation of water resources and introduces metrics for whole-building efficiency to preserve water ecosystems.

    • Materials and Resources: Aligns with ecological restoration by promoting circular economy principles and tracking waste streams to minimize landfill impact and preserve raw resources.
