LEED Building Search Guide

Understanding LEED Building Search

When searching for LEED-certified buildings, particularly for Commercial Interior projects, it's crucial to verify the base building's certification status under LEED v4, v4.1, or v5 BD+C rating systems. The U.S. Green Building Council (USGBC) maintains an online directory of certified projects, providing details such as the rating system version, certification level, final scorecard, and unique LEED identification number. For projects not listed, direct validation from the building owner or property manager is necessary.

Base Building Certification Verification

To ensure compliance with LEED ID+C: Commercial Interiors standards, the base building must have achieved certification under LEED v4, v4.1, or v5 BD+C. This ensures that sustainable practices are already integrated into the building's foundation, allowing tenants to leverage these initiatives for their interior spaces. The USGBC's online directory is a valuable resource for checking certification details and verifying that the base building has earned points for the relevant credits.

Steps to Verify Base Building Certification

• Access the USGBC's online project directory.
• Search for the building using its name, address, or LEED ID.
• Review the project's certification level and the credits it has earned.
• Contact the building owner or property manager if the project is not listed.

Surrounding Density and Diverse Uses

Projects in high-density areas benefit from better walkability and access to amenities. High-density neighborhoods promote efficient land use and sustainable growth patterns, protecting natural habitats and open spaces. To qualify under this criterion, the project site must meet specific residential and non-residential density thresholds, such as 7 or 12 dwelling units per acre and a non-residential density of 0.5 or 0.8 floor area ratio (FAR).

Density Requirements

Residential Density	7 or 12 dwelling units/acre
Non-Residential Density (FAR)	0.5 or 0.8
Total Combined Density	22,000 or 35,000 sq ft/acre

Access to Transit

Locating a project in a densely built environment with robust public transit options reduces environmental impact and enhances quality of life. Buildings near public transportation reduce vehicle miles traveled (VMT) and associated greenhouse gas emissions. Projects must meet minimum daily public transit service thresholds, such as 72 weekday trips and 30 weekend trips for 2 points, up to 360 weekday trips and 216 weekend trips for 5 points.

Public Transit Service Thresholds

Weekday Trips	Weekend Trips	Points
72	30	2
132	78	3
160	120	4
360	216	5

Walkable Location

A walkable location is defined by its proximity to essential services and amenities within a 0.25-mile radius. Projects can earn points based on their Walk Score® or the number of diverse uses within walking distance. For example, a Walk Score of 60-69 with 4-7 uses earns 1 point, while a score of 80 or more with 11 or more uses earns 3 points.

Walk Score and Proximity to Uses

Walk Score	Uses	Points
60-69	4-7	1
70-79	8-10	2
80+	≥11	3
