2010 Green Plumbing and Mechanical Code Supplement (09-PMGRN) is the first and only one publication that spells out the best sustainable plumbing and mechanical building practices in simple, straightforward code language. This publication is not a "greener" version of the Uniform Codes, but rather a separate document establishing requirements for green building and water efficiency applicable to plumbing and mechanical systems. This document covers:

• Water efficiency and conservation including: 
  • High efficiency fixtures, fixture fittings and appliances 
  • High efficiency plumbing fittings, fixtures and appliances 
  • Water softening equipment 
  • Cooling towers and evaporative coolers
  • Alternate water source usage, including gray water, rainwater and recycled water 
  • Water heating system, including equipment efficiency, insulation, recirculation, design and system controls 
• Energy efficiency for HVAC systems based on ASHRAE 90.1 and 90.2 
• Enhanced environmental quality for buildings based on ASHRAE 62.1 and 62.2.
