LEED Existing Building Scorecard Guide

Understanding the LEED Existing Building Scorecard

The LEED Existing Building Scorecard is a tool designed to assess and improve the sustainability performance of existing buildings. It evaluates various aspects of a building's operation and maintenance, focusing on energy efficiency, water usage, indoor environmental quality, and more. This scorecard helps building owners and managers identify areas for improvement and track progress over time. By adhering to the LEED v5 guidelines, projects can achieve certification levels that reflect their commitment to sustainable practices.

Key Components of the LEED Existing Building Scorecard

Location and Transportation (LT)

One critical aspect of the scorecard is the Location and Transportation category, which emphasizes the importance of a building's location in relation to public transit and walkable amenities. For instance, a building must offer access to a minimum number of daily public transit trips to qualify for points. According to LEED v5, a building must provide at least 72 weekday trips and 30 weekend trips to earn 2 points, with higher thresholds leading to more points.

Walkable Location

Another important criterion is the Walkable Location option, which requires the building to be situated in an area with a high Walk Score or within walking distance of a variety of services. The scorecard awards points based on the Walk Score and the number of different uses within a quarter-mile radius. For example, a Walk Score between 60 and 69 with 4 to 7 different uses earns 1 point, while a score of 80 or more with at least 11 different uses earns 3 points.

Practical Guidance from Real Project Experience

In our experience at ISG, we've seen that successful projects often start by conducting a thorough assessment of the building's current state. This includes evaluating the accessibility of public transit and the availability of nearby amenities. We recommend engaging with local transit authorities and using tools like Walk Score to gather accurate data.

Specific LEED v5 Requirements and Thresholds

Base Building Certification

For projects pursuing LEED ID+C: Commercial Interiors certification, locating in a building that is already certified under LEED BD+C (versions v4, v4.1, or v5) can significantly streamline the process. The base building must have earned points for either the Surrounding Density and Diverse Uses or Access to Quality Transit credits, depending on the version of LEED BD+C it was certified under.

Project Priorities

The Proj­ect Priorities credit allows teams to tailor their sustainability efforts to the unique needs of their project. This flexibility is crucial for addressing specific challenges, such as water conservation in arid climates or energy efficiency in data centers. Teams can earn up to 10 points by incorporating a variety of credits, including exemplary performance, regional priorities, and innovation strategies.
