LEED v5 New Construction & Major Renovations Guide

Understanding LEED v5 for New Construction and Major Renovations

LEED v5 for Building Design and Construction (BD+C): New Construction and Major Renovations is tailored for projects that involve the creation of entirely new buildings or significant overhauls of existing structures. This rating system applies to projects where at least 60% of the gross floor area is complete, encompassing both new constructions and major renovations that include substantial interior alterations, exterior shell modifications, and core and peripheral MEP (mechanical, electrical, plumbing) and service systems upgrades. These projects often require a new certificate of occupancy upon completion.

Eligibility Criteria and Scope

New Construction Projects

New construction projects under LEED BD+C: New Construction must cover the entire gross floor area of the building. The project must adhere to all prerequisites and credits outlined in the rating system, ensuring that the building meets stringent environmental standards from the ground up.

Major Renovations

For major renovations, the project must involve extensive interior and exterior work, including the building's primary structural components and core systems. Such projects typically render the primary function space unusable during construction, necessitating a new certificate of occupancy post-renovation.

Practical Guidance from Real Project Experience

Project Planning and Execution

From our experience at ISG, planning is key. Early engagement with LEED consultants can help streamline the process, ensuring compliance with all prerequisites and credits. For instance, integrating sustainable materials early in the design phase can significantly reduce waste and improve energy efficiency.

Meeting Specific Requirements

Projects must meet specific requirements based on their predominant use type. If a project is 60% or more residential, it must comply with residential-specific requirements. Similarly, schools, warehouses, healthcare facilities, and other specialized buildings have unique criteria to consider.

LEED v5 Requirements and Credit Points

Credits and Prerequisites

LEED v5 focuses on three main areas: decarbonization, quality of life, and ecological conservation and restoration. Each credit and prerequisite is linked to these areas, allowing project teams to clearly communicate their sustainability efforts. Credits range from energy efficiency and water conservation to indoor environmental quality and sustainable sites.

Thresholds and Benchmarks

To achieve certification, projects must meet certain thresholds for credits and prerequisites. For example, achieving a minimum number of points in energy efficiency and water conservation is crucial. Specific thresholds vary depending on the project type and scope.
