Kawneer LEED Recycled Content Guide

Understanding Kawneer's Contribution to LEED Recycled Content

Kawneer, a leading manufacturer of architectural aluminum systems, plays a significant role in helping projects achieve LEED certification, particularly in the area of recycled content. By integrating high-quality, sustainable materials into their products, Kawneer supports projects aiming to meet LEED v5 standards, specifically under the Materials and Resources (MR) category. This article delves into how Kawneer's offerings align with LEED requirements, focusing on the recycled content aspect.

LEED v5 Requirements for Recycled Content

Option 1: Reuse Existing Interior and Minimize Renovation

Under LEED v5, projects can earn up to 4 points by maintaining existing interior nonstructural elements and minimizing renovation. This includes furniture and interior nonstructural elements that are reused on-site. Projects must compile the total cost for these elements, pricing reused items as if they were new, and calculate the percentage of the total value that is reused. Points are awarded based on the percentage of furniture and interior systems reused on-site, ranging from 10% to 40%, earning 1 to 4 points respectively.

Option 2: Materials Reuse

Projects can also earn up to 3 points by demonstrating reduced environmental impacts through the reuse of existing building resources and incorporation of off-site reused materials. This involves conducting a salvage assessment before demolition or deconstruction to identify materials that can be retained on-site or diverted off-site to reuse markets. Materials sent for off-site reuse contribute to waste diversion under MRc5: Construction and Demolition Waste Diversion.

Practical Guidance from Real Project Experience

Incorporating Kawneer products into a LEED project can significantly boost recycled content scores. For instance, Kawneer's aluminum systems often contain a high percentage of recycled content, which can be documented and used to meet LEED criteria. It's crucial to maintain detailed records of the materials used, including weight or volume, and ensure that receipts and estimates are kept for verification purposes.

Specific LEED v5 Requirements and Thresholds

• On-Site Reuse: Projects must calculate the percentage of reused materials by cost, with thresholds set at 10%, 20%, 30%, and 40% for 1 to 4 points respectively.
• Off-Site Reuse: Materials salvaged on-site and sent for off-site reuse are valued at 200% of their weight for credit calculations.
• Recovered Materials: These are C&D waste materials that are diverted from landfills or incineration. Materials recovered through salvage and reused off-site are weighted at 200%.
