Water-related code and standard requirements will help communities conserve water.  

The International Code Council (ICC) and ASHRAE have partnered to publish 2015 WEP: Water Efficiency Provisions of the International Green Construction Code (IgCC). The publication is the most complete code resource on water conservation and efficiency. It includes water-related IgCC provisions to support jurisdictions facing critical water challenges and drought.

This compact, easy-to-use reference includes indoor and outdoor water efficiency and conservation provisions from the 2015 IgCC, as well as 2015 International Plumbing Code, Chapter 13 on Nonpotable Water Systems and water use provisions from ANSI/ASHRAE/USGBC/IES 189.1-2014 Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings.

2015 WEP: Water Efficiency Provisions of the IgCC covers:

  • water efficient plumbing
  • appliances
  • landscape irrigation
  • mechanical systems. 

The resource features the latest provisions for alternate water sources like rainwater, graywater and reclaimed water. It promotes water conservation associated with both the building and the building site, addressing numerous systems and components. It can be purchased online in soft cover format or PDF download.

“The updated WEP provides the most contemporary requirements for designers, policy makers and the construction community who are looking for ways to deal with severe droughts and the need to better conserve one of life’s most precious resources—water,” says Dominic Sims, CBO, Chief Executive Officer of the ICC. “The WEP provides a concise and comprehensive resource to address the challenges associated with water scarcity.”
