LEED v5 Prerequisites List - ISG Guide

LEED v5 Prerequisites List

The Leadership in Energy and Environmental Design (LEED) v5 rating system includes a set of prerequisites that every project must meet to achieve certification. These prerequisites cover essential aspects of sustainable design and construction, ranging from site selection to indoor environmental quality. Fulfilling these prerequisites is mandatory for any project aiming to secure LEED certification.

Understanding LEED v5 Prerequisites

To navigate the LEED v5 prerequisites effectively, it's crucial to understand their role within the broader framework of the LEED rating system. Each prerequisite addresses a fundamental aspect of sustainable, high-performance design and construction practices. They are organized into eight categories: Integrative Process, Planning, and Assessments (IP); Location and Transportation (LT); Sustainable Sites (SS); Water Efficiency (WE); Energy and Atmosphere (EA); Materials and Resources (MR); Indoor Environmental Quality (EQ); and Project Priorities (PR).

List of LEED v5 Prerequisites

• Integrative Process, Planning, and Assessments (IP): Includes prerequisites related to the integrative process and project planning.
• Location and Transportation (LT): Focuses on site selection and transportation strategies.
• Sustainable Sites (SS): Covers site development and management practices.
• Water Efficiency (WE): Addresses water conservation measures.
• Energy and Atmosphere (EA): Involves energy efficiency and renewable energy sources.
• Materials and Resources (MR): Deals with sustainable sourcing and waste management.
• Indoor Environmental Quality (EQ): Ensures a healthy and comfortable indoor environment.
• Project Priorities (PR): Highlights specific project goals and priorities.

Practical Guidance from Real Project Experience

From our experience at ISG, we've found that early engagement with the LEED prerequisites is key to a successful certification process. Teams should carefully evaluate the prerequisites against the project's specific goals, constraints, and characteristics. For instance, in the Energy and Atmosphere category, achieving the prerequisite often involves rigorous energy modeling and analysis to demonstrate compliance with the required performance metrics.

Specific LEED v5 Requirements, Thresholds, or Credit Points

Each prerequisite comes with specific requirements and thresholds. For example, in the Energy and Atmosphere category, projects must achieve a certain percentage improvement over baseline energy performance to meet the prerequisite. Similarly, in the Water Efficiency category, projects must reduce potable water consumption by a specified percentage compared to a baseline scenario.

Documentation Requirements

When preparing documentation for LEED v5 prerequisites, project teams should gather a variety of materials such as contract documents, calculations, reports, manufacturer product information, photographs, and descriptive narratives. For ongoing operations and maintenance (O+M) projects, additional documentation might include maintenance logs, energy and water bills, data from field or lab verified testing, and survey results.
