LEED Point Rating System

Local, Regional Materials


Materials Credit 5


The requirements of this credit state: "Use a minimum of 20% of building materials that are manufactured regionally within a radius of 800 km (500 miles)."

This means that a ready-mix or precast plant within 800 km (500 miles) of the building would qualify. Concrete will usually qualify since ready-mix plants are generally within 80 km (50 miles) of a job site. The percentage of materials is calculated on a cost basis. This credit is worth 1 point.

An additional point is earned if 50% of the regionally manufactured materials are extracted, harvested, or recovered within 800 km (500 miles). Ready-mix and precast plants generally use aggregates that are extracted within 80 km (50 miles) of the plant. Cement and supplementary cementitious materials are also primarily manufactured within 800 km (500 miles) of a job site.
