LEED v5 Checklist for New Construction

LEED Checklist for New Construction

When embarking on a new construction project aiming for LEED certification, it's crucial to understand the LEED v5 rating system and its prerequisites and credits. This guide breaks down the essential elements of the LEED v5 checklist for new construction, focusing on the eight main 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). Each category includes specific prerequisites and credits that projects must meet to achieve certification.

Understanding LEED v5 Requirements

The LEED v5 rating system for Building Design and Construction (BD+C) is designed for projects that are either new constructions or major renovations where at least 60% of the gross floor area is complete. These projects must register under the most appropriate LEED rating system and prepare documentation that includes plans, specifications, elevations, sections, construction details, calculations, reports, manufacturer product information, photographs, and descriptive narratives.

Credit Categories Explained

• Integrative Process, Planning, and Assessments (IP): Focuses on the collaborative process among design professionals, contractors, and owners to integrate sustainable strategies throughout the project lifecycle.
• Location and Transportation (LT): Encourages the selection of sites that minimize environmental impact and promote sustainable transportation methods.
• Sustainable Sites (SS): Aims to protect and restore the site’s natural features and reduce the environmental impact of development.
• Water Efficiency (WE): Seeks to minimize water usage through efficient fixtures and landscaping.
• Energy and Atmosphere (EA): Promotes energy efficiency and the use of renewable energy sources to reduce greenhouse gas emissions.
• Materials and Resources (MR): Encourages the use of sustainable materials and waste reduction strategies.
• Indoor Environmental Quality (EQ): Ensures a healthy and comfortable indoor environment for occupants.
• Project Priorities (PR): Allows project teams to focus on specific sustainability goals that align with their project's unique context and objectives.

Practical Guidance from Real Project Experience

In our experience at ISG, one of the key challenges in achieving LEED certification is aligning the project's goals with the LEED requirements. For instance, in the Energy and Atmosphere category, projects often struggle with meeting the stringent energy performance targets. However, by integrating advanced HVAC systems and optimizing building orientation, we have seen significant improvements in energy efficiency.

Specific LEED v5 Requirements and Thresholds

To illustrate, let's look at some specific requirements within the LEED v5 system:

• Water Efficiency (WE): Projects must achieve a 20% reduction in potable water use compared to a baseline scenario.
• Energy and Atmosphere (EA): Projects must demonstrate a 20% improvement in energy performance over a standard building as defined by ASHRAE 90.1.
• Materials and Resources (MR): At least 10% of the total value of the project's materials must be sourced regionally, within 500 miles of the project site.
