Is green a good public policy? Should all water-saving practices be added to the plumbing codes?

摘要

I recently attended a committee meeting on the IAPMO Green Plumbing and Mechanical Supplement, otherwise known as the Green Code. This is a group of fine professionals dedicated to helping the plumbing industry continue its move toward green construction practices. Both the IAPMO and ICC green codes are voluntary. You can use them if you want, but nothing in the code is mandatory.
