The LEED V4 EP Products & Materials language is "no antimicrobial agents (other than as a preservative) except where required by health codes and other regulations (e.g., food service and health care requirements)". Question is, where antimicrobial hand care products are used based on food service and health care codes, how is the purchase of these products handled? Is it basically invisible to the calculation (not in either the numerator or denominator used to calculate the %)?
