Several Materials and Resources credits give a bonus location valuation factor, which allows products extracted, manufactured and produced within 100 mi. (161 km) of the project to take double valuation in credit calculations. The intent of this bonus is

B . to avoid spreading products with potentially invasive non-native pests
C . to incentivize the purchase of products that support the local economy
D . to promote design with indigenous materials in order to maintain local aesthetic quality

Answer: C

Explanation:

The bonus location valuation factor in several Materials and Resources credits under LEED AP BD+C V4 is intended to incentivize the purchase of products that support the local economy. Products extracted, manufactured, and produced within 100 miles (161 km) of the project are valued at 200% of their cost within the calculations1.This adds value to locally produced products and materials2.
